What metric determines the measurement of Hess's Law? 

Enthalpy

100

This term describes the heat absorbed or released during a chemical reaction at constant pressure.

What is Enthalpy?

100

In the formula q= mcΔT, this variable represents the mass of the substance being heated or cooled. 

What is m?

This equation only depicts the molecules or ions that are actively involved in the reaction or those that undergo a change.

What is a Net ionic equation?

200

What is the equation for Hess's Law?

What is Enthalpy 

300

The process in which Solid changes to gas is called this.

What is Sublimation?

300

In a simple calorimetry experiment, the temperature change of water is used to calculate this property of the substance being tested.

This rule states that atoms tend to gain, lose, or share electrons in order to achieve a full outer energy level of eight electrons.

What is the octet rule?

400

This type of reaction is one where energy is released and has a negative enthalpy change. 

Exothermic Reaction 

400

The enthalpy change when one mole of substance melts at its melting point is called this.

What is the heat of fusion?

400

If the change in temperature doubles, what happens to the Q?

it doubles

500

The energy required to completely separate one mole of an ionic compound into its gaseous ions.

What is lattice energy?

500

In Hess's Law, when two or more reactions are combined, this must be done to their respective enthalpies. 

What is summing the enthalpy changes.

500

This term refers to the enthalpy change when one mole of a compound is burned completely in oxygen under standard conditions.

What is the standard enthalpy of combustion?

500

A 50.0 g sample of water is heated from 20.0 degrees Celsius to 30 degrees Celsius. How much heat energy is absorbed? (the specific heat capacity of water is 4.18 J/g C) 

the heat energy absorbed is 2090 J
