A 2.25 × 10² g of magnesium metal is placed into a (1.4000 × 10²) mL solution of hydrochloric acid. The reaction that takes place is as follows:
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g) (Δ)
Δ =?
The reaction is carried out in a simple calorimeter made of styrofoam cups. The temperature in the solution went from 21.0 degrees C to (3.7800 × 10¹) degrees C. According to this information, what is the experimental enthalpy of reaction for the reaction as written?
(answer to 3 S.D. in kJ)
Note: Your answer is assumed to be reduced to the highest power possible.
