what volume of ammonia gas, measured at 660.3 mmhg and 58.2c, is required to produce 6.46 g of ammonium sulfate according to the following balanced chemical equation 2NH3(g) + H2SO4(aq) ? (NH4)2SO4(s)
Write the balanced net ionic equations for the reactions that occur in each of the given cases as. Cr2(SO4)3(aq) + 3(NH4)2CO3 (aq) = Cr2(CO3)3 ( s) + 3(NH4)2SO4 ( aq).
the balloon reaches an altitude of 100m, where the pressure was 658 mmHg and the temperature was -8c. what was the volume in liters of the ballon at these conditions?
Assume that the complete combustion of one mole of ethanol to carbon dioxide and water liberates 1370 kJ/mol (?G°\' = -1370 kJ/mol). If the energy generated by the combustion of ethanol is entirely converted to the synthesis of a hypothetical comp..
