PS Ch. 7 Chemical Reactions Flashcard

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 factors can increase the rate of a chemical reaction?

Back

Factors that can increase the rate of a chemical reaction include increasing temperature, increasing concentration of reactants, and dividing large reactants into smaller pieces.

Front

What is the law of conservation of energy in chemical reactions?

Back

The law of conservation of energy states that energy cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What are the signs of a chemical change?

Back

Signs of a chemical change include a change in color, production of gas, formation of a precipitate, and a change in temperature.

Front

What is an inhibitor in a chemical reaction?

Back

An inhibitor is a substance that decreases the rate of a chemical reaction by preventing reactants from coming together.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

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.

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 a double-replacement reaction?

Back

A double-replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is thermal energy in the context of chemical reactions?

Back

Thermal energy is the energy that comes from the temperature of matter; it is often released or absorbed during chemical reactions.
