Chemistry - Thermochemistry Question with Solution | TestHub

For the neutralization between a strong and a strong base, equal number of moles of${\mathrm{H}}^{+}$(from acid) and$\bar{\mathrm{O}}\mathrm{H}$(from base) come out. For one mole of each following equation can be drawn

So, 0.35 mole of${\mathrm{H}}_2\mathrm{O}$is produced.
So, heat released$=(0.35\times 13.7) \mathrm{k}\mathrm{c}\mathrm{a}\mathrm{l}=4.795 \mathrm{k}\mathrm{c}\mathrm{a}\mathrm{l}$
