Answer:
a) No molecules of hydrogen
b) four molecules of ammonia
c) four left molecules of nitrogen.
Explanation:
The balanced reaction between nitrogen and hydrogen molecules to give ammonia molecules is:

Thus one molecule of nitrogen will react with three molecules of hydrogen to give two molecules of ammonia.
We have six molecules of each nitrogen and hydrogen in the closed container and they undergo complete reaction it means the limiting reagent is hydrogen. For six molecules of nitrogen, eighteen molecules of hydrogen will be required.
So six molecules of hydrogen will react with two molecules of nitrogen to give four molecules of ammonia.
The product mixture will have
a) No molecules of hydrogen
b) four molecules of ammonia
c) four left molecules of nitrogen.
Potential energy is not in motion, which means the roller coaster wouldn't be moving. do therefore it is kenetic energy because that means movement energy. hope this helps
The answer is , C. Both the atomic mass and the atomic number increase from left to right .
Answer:

because of the sun its so hot
because its cold snowing
because the oceans is water you can swimming
Explanation:
that is
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element.
