This question has multiple parts.
a. in a coffee-cup calorimeter, 1.81 g nh4no3 was mixed with 85.00 g water at an initial temperature 25.00oc. after dissolution of the salt, the final temperature of the calorimeter contents was 23.34oc.
assuming the solution has a heat capacity of 4.18 j/g∙oc, and assuming no heat loss to the calorimeter, calculate the enthalpy of solution (∆hsoln) for the dissolution of nh4no3 in units of kj/mol.
∆ = kj/mol
b. in a coffee-cup calorimeter, 1.81 g nh4no3 was mixed with 85.00 g water at an initial temperature 25.00oc. after dissolution of the salt, the final temperature of the calorimeter contents was 23.34oc.
if the enthalpy of hydration for nh4no3 is -630. kj/mol, calculate the lattice energy of nh4no3.
lattice energy = kj/mol

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
