In the laboratory a student determines the specific heat of a metal. he heats 19.5 grams of copper to 98.27 °c and then drops it into an insulated cup containing 76.3 grams of water at 24.05 °c. when thermal equilibrium is reached, he measures the final temperature to be 25.69 °c. assuming that all of the heat is transferred to the water, he calculates the specific heat of copper to j/g°c.

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.
