All of the reactions that you see are uncut and play at the original speed. This is a classic chemical reaction. It's called the iodine clock reaction. There are several variations of how this chemical reaction can be performed using different chemicals than the ones I used in the video. You can order clock reaction kits from several science related websites. You can also use simple store bought chemicals like vitamin C, iodine, hydrogen peroxide and starch. A quick internet search will turn up multiple ways of performing the experiment. Even though I've played around with the clock reaction experiment before I've always wanted to capture the reaction as the liquid was being poured. To me, this is the most stunning way of demonstrating the reaction. Here's the other version of the clock reaction I made several years ago http://www.youtube.com/watch?v=qeDhaWEEvfg

Precipitation Reactions: Crash Course Chemistry #9
 
11:31
A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this episode of Crash Course Chemistry, we learn about precipitation, precipitates, anions, cations, and how to describe and discuss ionic reactions.

Determining States of Matter in Chemical Reactions
 
05:28
How to predict states of matter for synthesis, decomposition, single replacement, double replacement and combustion reactions. Many of these are highly variable where alternate states of matter could be achieved, these are some guidelines for starting in order to simplify for a high school level chemistry class. Single replacement and double replacement should be assumed to be taking place in water unless otherwise stated. A solubility chart can be used to determine if the salts will be solid (insoluble) or aqueous (soluble). Synthesis and decomposition should be assumed not to be in water unless guided in that direction. Salts will be solid although can be in the liquid state for intense heating or for electrolysis. Combustion fuels are typically burned in the gaseous state but can start initially in the gas, liquid or solid state.

Determining states of matter for chemical reactions
 
04:36
common states of matter for chemicals in the common introductory chemical reactions (synthesis, decomposition, single displacement/replacement, double displacement, combustion, neutralization) are discussed. For single and double displacement reactions you should assume that the reactions are all in water therefore the salts should be solid or aqueous. For synthesis reactions where water is added, the products can also be aqueous. Decomposition reactions where heating is going on are usually not in water, but electricity run through a binary salt usually are aqueous. Acids and bases are typically aqueous. Typical liquids are bromine, water (sometimes a gas, steam), and mercury. Typical gases include many diatomics N2, O2, F2, Cl2, H2 and CO2, H2O, and other nonmetal oxides such as SO2, NO2 etc. Find more chemistry help here: https://sites.google.com/site/thechemistrytranslator/chemistry---milam-plymouth

What are endothermic and exothermic reactions | Chemistry for All | FuseSchool
 
04:17
An exothermic reaction gives off energy to the surroundings; like a fire giving off heat. An endothermic reaction takes in energy from the surroundings; like a snowman melting. Exothermic reactions transfer energy to the surroundings, and this energy is usually heat energy, they cause the surroundings to heat up. Just like a bonfire keeping everyone warm. As well as combustion (burning), other examples of exothermic reactions are: - Neutralisation reactions between acids and alkalis - The reaction between water and calcium oxide - Respiration. It is easy to detect an exothermic reaction - just get your thermometer and see if the temperature increases. Most chemical reactions are exothermic, because heat is given out. Physical processes can also be endothermic or exothermic. When something freezes, it goes from liquid to solid. Bonds need to be made for this to happen, and to make bonds you need to do some work, thus energy is given out and freezing is exothermic. Similarly, when condensation happens - because a gas is going to liquid, again bonds need to be made and so energy is given out. So freezing and condensation are exothermic. Because in exothermic reactions, energy is given out to the surroundings. This means that the energy of the reactants is higher than the energy of the products. Endothermic reactions are less common. They take in energy from the surroundings. The energy being transferred is usually heat. So in endothermic reactions, the surroundings usually get colder. Some examples of endothermic reactions are: - Electrolysis - The reaction between sodium carbonate and ethanoic acid - Photosynthesis. Endothermic reactions can also be seen in physical processes. When something melts it goes from a solid to a liquid. For this to happen, bonds need to be broken. And to break bonds, energy needs to be put in. Boiling is also endothermic because energy needs to be put in to break the bonds for the liquid to turn to gas. Because in endothermic reactions, energy is added to the reaction, the energy of the products is higher than the energy of the reactants. And again, we can detect endothermic reactions with a thermometer because the temperature would get colder. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

Supersonic detonation of hydrogen and oxygen gas
 
04:18
Chief Scientist Carl Nelson demonstrates how the combustion of hydrogen gas depends on the amount of oxygen present. A balloon filled with 100% hydrogen is ignited with a small flame. As the flame ignites the hydrogen gas, it combines with oxygen in the surrounding air. A large, but relatively slowly moving ball of fire is created. This is called a deflagration. Next, a mixture of two parts hydrogen and one part oxygen gas is used to create a foam of soap bubbles. The amount of oxygen available here makes a significant difference in the size and sound of the reaction. 2 H2(g) + O2(g) → 2 H2O(g) + Energy This reaction proceeds so quickly (a detonation) that a supersonic shock wave is generated. The sound level is significantly louder and the ball of flame generated is much smaller. Note that the final product of the reaction is water and energy.

The equilibrium constant is a ratio of the concentration of the products to the concentration of the reactants. If the K value is less than one the reaction will move to the left and if the K value is greater than one the reaction will move to the right. Do you speak another language?

Metals react with acids to produce salt and Hydrogen | Acid & Bases | Chemistry
 
01:50
This activity studies the reaction between metals and acids by dropping some zinc granules into dilute hydrochloric acid and dilute sulphuric acid. In each case, a gas is released and when this gas is tested with a matchstick flame, we get a characteristic popping sound and see that the matchstick burns more brightly. This indicates that the gas produced is hydrogen. Zinc forms the salt zinc sulphate with sulphuric acid and zinc chloride with hydrochloric acid and releases hydrogen gas in both cases. In general, a metal reacts with an acid to form a salt and releases hydrogen gas.

√ Le Chatelier’s principal | Chemical Monitoring and Management | Chemistry
 
20:29
#iitutor #Chemistry #ChemicalMonitoringAndManagement https://www.iitutor.com/ For any given chemical process, the correct raw materials need to be brought together in the right place, at the right time, and under the right conditions. Chemists need to carefully monitor processes to ensure optimum conditions. Important conditions include: • concentration of reactants and products • presence of a catalyst • temperature • pressure (only if gases are involved) If a system is in equilibrium and a change is made that upsets the equilibrium, then the system alters in such a way as to counteract the change and a new equilibrium is established. The Haber process involves an equilibrium reaction, and knowledge of Le Chatelier’s principle is needed in order to predict how reaction conditions will impact on the production of ammonia by this process Rules of Le Chatelier’s Principle Rule 1: Temperature If the forward reaction is endothermic, increasing the temperature favours the formation of the product.The yield of product will be increased. If the forward reaction is exothermic, reducing the temperature favours the formation of the product. The yield of the product will be increased. These rules apply to all reactions. Rule 2:Pressure applies only to reactions with one or more gaseous reactants or products. Increasing the system pressure (by reducing the volume) causes the equilibrium to shift to the side of the equation with the least number of gaseous molecules. Decreasing the system pressure (by increasing the volume) causes the equilibrium to shift to the side of the equation with the most number of gaseous molecules. Where there are equal numbers of molecules on the reactant and product sides, pressure has no effect on the position of the equilibrium. Rule 3:Concentration Increasing the reactant concentration shifts the equilibrium to the right to make more products and to reduce the concentration of the added reactant. Decreasing the concentration of a reactant shifts the equilibrium to the left to make more of that reactant. Consequently the concentration of products decreases. Rule 4:Catalysts Catalysts make reactions go faster. They do not affect the position of equilibrium. Catalysts cause the forward and reverse reactions to speed up by equal amounts. Catalysts are useful because they lower the activation energy, and equilibrium is achieved faster. This is important in industry as there are considerable savings to be made in time and energy as reactions can be conducted (where appropriate) at lower temperatures.

This experimental demonstration involves the combustion of a gaseous hydrocarbon, in particular butane. Qualitative identification of gaseous combustion products is as follows. Initially, we pump the gaseous products of combustion, over anhydrous copper (II) sulfate to indicate the presence of water vapor. Finally, they are passed through a calcium hydroxide solution to indicate the presence of carbon dioxide. C4H10(g) + 13/2O2(g) → 4CO2(g) + 5H2O(g) ΔΗC(C4H10) = ─2877 kJ/mol CuSO4(s) + 5H2O(l) → CuSO4∙5H2O(s) CΟ2(g) + Ca(OH)2(aq) → CaCO3(s) + H2O(s)

Super Common Mistake: Diatomic Elements
 
04:24
Shouldn't there be two atoms of every diatomic element? Many students get confused by the diatomic elements. Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, and Fluorine always form diatomic molecules and pair up. You don't find just one atom of a diatomic element on its own. But then, why do many chemical formulas like H2O and LiBr, have just one atom of a diatomic molecule? We talk about this super common mistake and misconception.

Decomposition Reaction | #aumsum #kids #education #science #learn
 
05:01
Decomposition Reaction. A reaction in which a compound splits up into two or more simpler substances is known as a decomposition reaction. Let us take an example. Ferrous Sulfate. Color of ferrous sulfate crystals is green. Heat the test tube. The color of ferrous sulfate crystals first changes to white as it loses molecules of water of crystallization. Ferrous sulfate changes to reddish brown due to the formation of ferric oxide. Sulfur dioxide and sulfur trioxide gases are also released in this reaction. They have a pungent and rotten smell due to the burning of sulfur. These gases are toxic. They should not be inhaled. Ferrous sulfate splits up into 3 simpler substances, that is, ferric oxide, sulfur dioxide and sulfur trioxide.

Sulphur Dioxide forms an acid | Acids & Bases | Chemistry
 
01:56
If we leave a glass of water in the open air for a few days, the water will turn it slightly acidic. This happens because the gaseous carbon dioxide in air dissolves in water to form carbonic acid. Like carbon dioxide, which is an oxide of a non-metallic element (Carbon), this property is also true generally true for oxides of other non-metals. The video demonstrates the heating of sulphur in a test tube until it oxidizes (burns) and releases sulphur dioxide smoke. Sulphur dioxide does not affect red litmus but changes the colour of wet blue litmus paper to red, showing us that sulphur dioxide gas is acidic. Sulphuric acid is produced by dissolving sulphur dioxide in water. Many industrial processes produce sulphur dioxide gas as a pollutant and when this gas dissolves in rain water, we get acid rain which is harmful to the biosphere.
