Question

Match each vocabulary word with its definition. Match the items in the left column to the items in the right column. 1. The amount of heat released or absorbed by a reaction heat of reaction 2. The change in enthalpy (heat content) that occurs in the process of converting reactants to products in a chemical reaction specific heat 3. a reaction which absorbs heat from the surrounding space exothermic reaction 4. a reaction which gives up heat to the surrounding space endothermic reaction 5. the amount of heat required to raise the temperature of one gram of a given substance by one degree Celsius enthalpy of reaction

Answer 1

Answer:

endothermic reaction a reaction which absorbs heat from the surrounding space

enthalpy of reaction The amount of heat released or absorbed by a reaction

exothermic reaction a reaction which gives up heat to the surrounding space

heat of reaction The change in enthalpy (heat content) that occurs in the process of converting reactants to products in a chemical reaction

specific heat the amount of heat required to raise the temperature of one gram of a given substance by one degree Celsius

Explanation:

I just did the Enthalpy assignment

Answer 2

The reactants in the endothermic reactions absorb the heat from the surroundings. Whereas the system that releases the heat is called an exothermic reaction. Thus, the correct matches are 1. e, 2. a, 3. d, 4. c, and 5. b.

What are endothermic reactions?

In endothermic reactions, the reactants absorb the heat from the outer environment and produce the products. Hence, option d is correct.

The correct matches are:

• The heat absorbed or released by the system reaction is the enthalpy. Hence, option e is correct.

• The system that releases or gives the heat out is called an exothermic reaction. Hence, option c is correct.

• The enthalpy change occurs when the reactants yield products. Hence, option a is correct.

• The heat required to increase the degree of the temperature of a gram of substance is called specific heat. Hence, option b is correct.
