Answer:
No it is not a physics because in this there is about classification of element so it is in chemistry that's why it is not physics.

Answer : The concentration of the
solution is, 2.16 M
Explanation :
To calculate the concentration of base, we use the equation given by neutralization reaction:

where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is
.
We are given:

Putting values in above equation, we get:

Thus, the concentration of the
solution is, 2.16 M

Answer:- 
Explanations:- It is given that the charge for A is +2 and the charge for B is -3. The over all compound is neutral means the over all charge is zero. For making the over all charge zero, we need 3 positive ions and 2 negative ions. This makes a +6 charge for A and -6 charge for B and the over all charge is zero.
Also, if we think about the criss cross then charge of A becomes the subscript of B and the charge of B becomes the subscript of A.
So, the formula of the ionic compound is
. In this compound the ratio of A to B is 3:2.
The balanced equation could be shown as:
