A2.50-g sample of powdered zinc is added to 100.0 ml of a 2.00-m aqueous solution of hydrobromic acid in a calorimeter. the total heat capacity of the calorimeter and solution is 448 j/k. the observed increase in temperature is 21.1 k at a constant pressure of one bar. using these data, calculate the standard enthalpy of reaction. zn(s) + 2hbr(aq) --> znbr2(aq) + h2(g)
