Balancing Equations and Identifying Reaction Type

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products. This means that the number of atoms must remain constant.

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means ensuring that the number of atoms of each element is the same on both sides of the equation, reflecting the law of conservation of mass.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are products in a chemical equation?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

How do you identify a chemical change?

Back

A chemical change can be identified by signs such as color change, gas production (bubbling), temperature change, or the formation of a precipitate.

Front

What is the significance of coefficients in a balanced equation?

Back

Coefficients indicate the number of molecules or moles of each substance involved in the reaction, helping to balance the equation.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

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.
