A2.56g sample of anthracene c14h10, was burned to heat an aluminum calorimeter (mass= 948 g). the calorimeter contained 1.50 l of water with an initial temperature of 20.5oc and a final temperature of 34.3oc.

The agent of mechanical weathering in which rock is worn away by the grinding action of other rock particles is call

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.

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion
