a) Number of protons = number of electron in the atom = atomic number
So it has 7 protons answer
N-3 has gained 3 electron so number of electrons + 7+3
= 10 answer
Answer:

Explanation:
the reaction can't move to left because H is positive
Answer: The pressure of a gas will increase when there is a decrease in the volume of the gas.
Explanation: according to Boyle's law, the volume of a gas will decrease when the pressure is increased at constant temperature and vice versa.
Time because even if time changes potential and kinetic energy won’t be affected as much
Answer:
The particles need energy to overcome the attractions between them. As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles of gas in the liquid.
