Find the molar enthalpy of combustion of ethane (C2H6(g)) , given that the combustion of 37.8 g of ethane raises the temperature of a calorimeter of total heat capacity 51.2 kJ/∘C by 35.6 ∘C. 3 or more sig. figs. PLEASE ANSWER THIS

Brainliesttt me asap! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

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.
