Can someone please provide answer and step by step explanation? Thanks!

3.069 mol of hydrochloric acid was reacted at constant pressure with 5.529 mol of sodium hydroxide. This reaction, initially

Answer 1

Answer #1

3.069 mol of HCl and NaOH will react

Given:

Q = -178.002 KJ

Negative because heat is released

So,

Delta H = Q / number of mol reacting

= -178.002 KJ / 3.069 mol

= -58.00 KJ/mol

Answer: c
