What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 → CO2 + 2H2O.

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. Example: A + B → AB.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a chemical reaction where a single compound breaks down into two or more simpler products. Example: AB → A + B.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: A + BC → AC + B.

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms for each element is the same on both sides of the equation.

What is the balanced equation for the combustion of methane?

Back

CH4 + 2O2 → CO2 + 2H2O.

What is the balanced equation for the reaction of aluminum and chlorine?

Back

2Al + 3Cl2 → 2AlCl3.

What is the balanced equation for the reaction of silver bromide and gallium phosphate?

Back

3AgBr + GaPO4 → Ag3PO4 + GaBr3.

What is the difference between a reactant and a product?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.
