Answer:
<h2>12 atm</h2>
Explanation:
To find the initial pressure we use the formula for Boyle's law which is

Since we are finding the initial pressure

From the question we have

We have the final answer as
<h3>12 atm</h3>
Hope this helps you
Answer:
no of neutron = atomic mass - atomic number
Explanation:
here
atomic mass = 64
atomic number = 30
no of neutron = <span>64−30</span>
no of neutron = 34

Answer:- 7 protons and 10 electrons.
Solution:- Atomic number for nitrogen atom is 7.
For neutral atom, atomic number = number of protons = number of electrons
An ion is formed if electrons are lost or gained by the neutral atom. Here we have nitride ion where nitrogen has -3 charge. This negative 3 charge indicates the gain of 3 electrons by nitrogen atom. The number of protons remains unchanged, means there are still 7 protons.
electrons for the given ion = 7 + 3 = 10
So,
ion has 7 protons and 10 electrons.
