The equation N2+H2= NH3 is balanced. This is because N2 + 3H^2 ➡️ 2NH^3
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element.
we are asked in this problem to determine the mass of a liquid in a small container. In order to determine the mass, we use an analytical balance for greater accuracy by first weighing the whole system (liquid+beaker). Then transfer the liquid to another container and completely dry the beaker (wash and dry). measure the weight of the beaker. The mass of the liquid is equal to the mass of the system minus the mass of the beaker.
Answer:
Well yes and no
Explanation:
The molecules move, but in place. They are constantly vibrating, rotating and so forth.
Atoms do not move at all
