When 50.0 mL of 1.000 M HCl is reacted with 50.0 mL of 1.000 M NH4OH, the solution's temperature increases 8.65 °C. Calculate qs
olution in units of kJ. The specific heat of the salt solution is 4.184 J/g-°C and the density is 1.010 g/mL.

Answer:
Explanation:
Total volume of solution = 100 mL .
Total mass of the solution = 100 x 1.01 g
= 101 g
specific heat of solution = 4.184 J/g-°C
rise in temperature = 8.65 °C
heat released = mass x specific heat x rise in temperature
= 101 x 4.184 x 8.65
= 3655.35 J
= 3.655 kJ .
qsolution = 3.655 kJ .
