Question 1 and 2 Pre-Laboratory Assignment1. Sam performed a reaction in lab where he mixed a dilute solution of hydrochloric acid into adilute solution of sodium hydroxide. The temperature of the mixed solution rose immediatelyfrom 20.0°C to 30.0 °C. Was the reaction Sam performed in the lab exothermic or endothermic?What evidence (observation) for this reaction supports your inference?2. Define Hess's Law.3. Predict the target reaction which can be obtained by adding step 1 and 2 shown below. Alsocalculate the heat of reaction of the target reaction, which can be obtained by AH" from step 1 and2.Step 1 2 Hy(g) + N>(g)N,H,(g)AH = 95.4Step 2 NgH,(g) + Ha(g)2 NH3(g)AH"=-187.6 kJkJ81

Exothermic reaction is a reaction where heat (energy) is released in the reaction.
