A. Elastic
Explanation:
an elastic collision is one which there is no overall loss of kinetic energy
Answer:
177 mmHg
Explanation:
Given that:
The sample of a gas is with Pressure (1)
= 500 mmHg
The initial temperature
= 773 K
The final temperature
= 273 K
Using ideal gas equation:

Atomic Mass will be 23 the new magnesium formed will be its isotope of magnesium.
We know that,
In stable condition
Number of electrons = Number of protons
Atomic number represents number of proton .
So, here number of proton is 12
Therefore, number of electron is 12
We know that -
Atomic mass = number of protons +Number of neutron
So if magnesium loses one neutron i.e. new number of neutron is 11
then its atomic mass changes.
New atomic mass will be
Atomic mass = 
Atomic mass = 23
This new element with atomic mass 23 and atomic number 12 is the isotope of magnesium.
