Part B question 1 Answer: C
that’s the on that makes most sense
Answer: answer A
Explanation: because it gives more detail and a summarizations
Answer: Thus molarity of
is 1.35 M
Explanation:
To calculate the volume of acid, 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 KOH.
We are given:

Putting values in above equation, we get:

Thus molarity of
is 1.35 M
Alkaline Earth Metals and Alkali Reactive metals because they need more electrons to acquire octet.
