What coefficient is placed in front of O2?
The coefficient for O2 is 7.
When C2H4 reacts with oxygen One product is water?
When C2H4 reacts with oxygen, one product is water. Pentane (C5H12) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) according to the following reaction. Answer the following question(s) about this reaction.
What is the coefficient of H2?
In our balanced chemical equation, the coefficient for H2(g) is 1, and the coefficient for HCl(g) is 2. The molar ratio between these two compounds is therefore 1:2. This tells us that for every 1 mole of H2(g) that is consumed in the reaction, 2 moles of HCl(g) are produced.
What type of chemical reaction is H2 O2 → H2O?
A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
What happens to hydrogen peroxide in water?
Hydrogen peroxide slowly decomposes into water and oxygen. An elevation of temperature and the presence of pollutions enhance this process. This is a redox reaction. Hydrogen molecules partly function as reductors and partly as oxidizers.
Is KClO3 acid or base?
Potassium chlorate is an ionic compound that is dissociated into K+ and ClO3- ions. Neither of these ions is hydrolyzed in water so the pH should be 7. So potassium chlorate is neither an acid nor a base. It is a salt formed from the reaction of the acid HClO3 and the base KOH.
What happens when you put a gummy bear in potassium chlorate?
Summary: When heated, potassium chlorate decomposes, producing sufficient oxygen to ignite the sugar in the gummy bear. Since the oxidation of the sugar is very exothermic, sodium chlorate continues to decompose to oxygen, and the rate of combustion becomes very rapid.
Do gummy bears explode?
Why do gummy bears explode when added to hot potassium chlorate? This link shows that a gummy bear explodes when in contact with heated potassium chlorate, KClO3.
