For the reaction ? N2+? H2 →? NH3 ,
what is the maximum amount of NH3 which
could be formed from 12.26 g of N2 and 18.46 g
of H2?
Answer in units of g.

Mercury turns to a vapor at 629.88 k. how much heat is lost when 75.0 g of mercury vapor at 650 k condenses to a liquid at 297 k?

Is the flow of energy during vaporizing more like the flow during melting or during freezing

Reacting masses1 calcium carbonate breaks down on heating to produce calcium oxide and carbondioxide gas.caco3 + cao + co2a student heats 15 g of calcium carbonate strongly in a crucible.relative atomic masses (a): ca = 40, c = 12, o = 16.calculate the mass of calcium oxide produced by this reaction.(5 marks)
