<u>Answer:</u> The blanks are completed below.

<u>Explanation:</u>

Enthalpy change of the reaction is defined as the difference in the potential energy of the products and the potential energy of the reactants. It is represented as \Delta H

Mathematically,

\Delta H_{rxn}=\Delta H_{products}-\Delta H_{reactants}

When \Delta H of the reaction is negative, then potential energy of the products is less than the potential energy of the reactants. So, energy is being released.

Thus, a +ve \Delta H means that energy is released from a reaction.

When \Delta H of the reaction is positive, then potential energy of the products is more than the potential energy of the reactants. So, energy is being absorbed.

Thus, a -ve \Delta H means that energy is absorbed from a reaction.

Matter is anything that has mass and takes up space. Which units of measurement can you use to describe these two properties?
Sindrei [870]

Answer is: D. kilograms and cubic millimeters .

Kilogram (symbol: kg) is the base unit of mass (anything that has mass in this question) in the International System of Units and cubic millimeter (symbol: mm³) is volume measurement unit (takes up space).

Second (symbol: s) is the base unit of time in the International System of Units and kilometer (symbol: km) is a unit of length in the metric system.

Gram (symbol: g) is a metric system unit of mass, but millimeter (abbreviated: mm) is an unit of distance in the metric system.

Yard (abbreviation: yd) is an unit of length and liter (symbol: l) is metric unit of capacity.

kari74 [83]
The correct answer is "greenhouse gases." Certain gases in the atmosphere, like carbon dioxide, nitrous oxide, and methane, absorb heat and prevent it from escaping into space. These gases are called greenhouse gases.
