HPS Ch 14 & 15 Review

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs more thermal energy than it releases.

Front

What do organic compounds contain?

Back

Organic compounds contain carbon bonded to hydrogen.

Front

What type of hydrocarbon has a double bond?

Back

An alkene is characterized by the presence of a double bond.

Front

Back

This is a combustion reaction.

Front

What factors can increase the rate of a chemical reaction?

Back

Increasing temperature, increasing concentration, and increasing surface area can all increase the rate of a reaction.

Front

Define combustion reaction.

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What is the difference between an alkane and an alkene?

Back

Alkanes are hydrocarbons with single bonds, while alkenes have at least one double bond.

Front

What is the general formula for alkenes?

Back

The general formula for alkenes is CnH2n.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases more thermal energy than it absorbs.

Front

What is the significance of surface area in a chemical reaction?

Back

Increasing the surface area of reactants increases the rate of reaction by allowing more collisions between particles.
