The average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume will not changes.
<h3>What is average kinetic energy?</h3>
The product of half the mass of each gas molecule with the square of root mean square speed is the average kinetic energy of the molecules.
And this average kinetic energy is deirectly proportional to the absolute temperature of the system but in the given question temperature and volume of the gas is constant. So that there is no change in average kinetic energy of molecules when they collide.
Hence no change in the average kinetic energy of a gas takes place.

Answer:
The both refer to the same term.
Explanation:
The heat of neutralization also called the enthalpy of neutralization. It is the heat evolved or the enthalpy change when one equivalent of acid reacts with one equivalent of a base under standard conditions to form salt and water only.
Answer:
C) The most efficient fusion reactors would use heavier forms of hydrogen.
Explanation:
From the information presented to us in the question, the third sentence reveals that heavier forms of hydrogen produces larger amount of energy and most importantly reacts more efficiently when fusion occurs.
<em>In fact, the </em><u><em>heavy isotopes of hydrogen—deuterium and tritium—react more efficiently</em></u><em> with each other, and, when they do undergo fusion, they yield more energy per reaction than do two hydrogen nuclei. </em>
Answer:
168.812 g/mol
Explanation:
atomic mass. of Be= 9.012
atomic mass of Br= 79.90
because there is a 2 after Br you double the atomic mass
79.90(2)= 159.8
To find the molar mass add the atomic masses of each element
9.012+159.8=168.812
