5.0 Chemical Reactions

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature.

Front

What type of reaction is represented by the equation: AgF + CaCl2 → AgCl + CaF2?

Back

This is a double replacement reaction.

Front

What is the effect of smaller particle size on the surface area for a reaction?

Back

Smaller particle size allows for a larger surface area to be exposed for the reaction.

Front

What does it mean for a chemical equation to be balanced?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, obeying the law of conservation of mass.

Front

Which of the following is a correctly balanced equation: 6CO2 + 6H2O → C6H12O6 + 6O2?

Back

This equation is correctly balanced.

Front

What type of reaction is represented by the equation: 3Mg + N2 → Mg3N2?

Back

This is a synthesis reaction.

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 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.
