Work, heat and internal energy 1. Calculate the work done during the reaction of 20 g Na$_2$CO$_3$ with excess HCl at a temperature of 25 $^\circ$C under atmospheric pressure, $p$ = 101.3 kPa. Hint: First write out balanced equation for neutralization reaction (acid + base $\rightarrow$ salt + CO$_2$ + H$_2$O). Then compute number of moles of Na$_2$CO$_3$ and infer number of moles of CO$_2$ gas evolved. Then compute work as: $w = -\Delta n_{gas}RT$. Make sure to express all quantities in SI units. Answer: -467.8 J or 0.47 kJ
