LCM and Reaction Types

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 more complex product.

Front

What are indicators of a chemical change?

Back

Indicators of a chemical change include temperature change, color change, bubbling or fizzing, and the formation of a precipitate.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, producing heat and light, typically resulting in carbon dioxide and water.

Front

How do you calculate the mass of a missing reactant in a chemical reaction?

Back

To find the mass of a missing reactant, use the law of conservation of mass: total mass of reactants = total mass of products.

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; it is conserved.

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.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

Front

What is the general form of a chemical equation for a synthesis reaction?

Back

The general form is A + B → AB, where A and B are reactants and AB is the product.

Front

What is the general form of a chemical equation for a decomposition reaction?

Back

The general form is AB → A + B, where AB is the compound that breaks down into its components.
