Unit 5 Test Retake

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

How do you determine if a reaction is endothermic or exothermic based on temperature change?

Back

If the temperature decreases during the reaction, it is endothermic. If the temperature increases, it is exothermic.

Front

What is the balanced equation for the reaction of sodium and chlorine gas to form sodium chloride?

Back

2 Na + Cl2 → 2 NaCl.

Front

What type of reaction is represented by the general formula AB + CD → CB + AD?

Back

This is a Double Replacement reaction.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler products.

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 in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds switch places, forming two new compounds.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light.
