If the solution has a specific heat capacity of 3.95 jg k, Ask an Expert

Academics

A temperature increase of 67.4 K was recorded after 1.500 g of metallic magnesium (24.305 amu) reacted completely with 100.0 mL of 1.00 M aqueous HCl in a non-ideal coffee cup calorimeter with a heat capacity of 16.0 J/K. If the solution has a specific heat capacity of 3.95 J/(g K) and a density of 1.015 g/ml, what is the DeltaH for the following reaction in kJ?

Mg(s)+2H(positive)(aq) ---> Mg(2positve)(aq)+H2(g)
