A coffee cup calorimeter contains $0\mathrm{.}0375$molHCl dissolved in $150mL$ of solution at $20\mathrm{.}51C.$ When $1\mathrm{.}75g$ of solid zinc metal is placed in the calorimeter the temperature rises to $29\mathrm{.}02C.$ Assume that no heat is lost to the surroundings.

$Zn(s)+2HCl(aq)-ZnC{l}_2(aq)+H_2(g)$

Find the limiting reactant.

Find the amount of heat lost or gained by the calorimeter.

Find the heat of reaction answer in $k\frac{J}{m}ol$

Enter your answer for $3$ in the box.

Use the total mass $($zinc $+$ acid$)$

Should the sign be $+$ or $-?$

Divide $q$ by moles of the limiting reactant to find $H$
