Question
Preform that same addition of equations to the following two reactions NaOH(aq) + NH_4Cl(aq) rightarrow NaCl(aq) + NH_4OH(aq) NH_4OH(aq) + HCl(aq) rightarrow NH_4Cl(aq) + H O(l) If reaction 2 of this lab raises the temperature of 100.0 grams of water by 3.5 degree C, calculate the heat, q, gained by the water. q = m times delta T times 4.184 J/g degree C If the heat of reaction is equal but opposite in sign to the heat gained by the water. Use the answer to question 5 to determine how many kJ per mole the reaction of 0.50 of Mg produced.Explanation / Answer
The heat gained by water = m*c*delta T
= 100 g * 4.184 J/g C * 3.5 C
= 1464.4 J
Enthalpy of reaction = -1464.4 J
