Calcule o calor especifico do estanho sabendo que foram necessarias 100 cal para elevar em 20ºc a temperatura de 100 g de estanho

If 200.0g of copper(ll) sulfate react with an excess of zinc metal, what is the theoretical yield of copper

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

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.
