What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. It involves breaking and forming bonds between atoms.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: A + B → AB.

Front

What is a decomposition reaction?

Back

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

Front

What is a single displacement reaction?

Back

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

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD → AD + CB.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light. Example: Hydrocarbon + O₂ → CO₂ + H₂O.

Front

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.

Front

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.

Front

What is a word equation in chemistry?

Back

A word equation is a way of representing a chemical reaction using the names of the reactants and products. Example: Aluminum + Hydrochloric Acid → Aluminum Chloride + Hydrogen.

Front

What is a reactant?

Back

A reactant is a substance that undergoes a chemical change in a reaction. It is present at the start of the reaction.
