Determine the number of moles and mass requested for each reaction in exercise 4.42.
refer to exercise 4.42.
write the balanced equation, then outline the steps necessary determine the information equation in each of the following:
(a) the number of moles than the mass of the chlorine cl2 required to react with 10.0 g of sodium metal na to produce sodium chloride nacl
(b) the number of moles and the mass of the oxygen formed by the decomposition of 1.252 gram of mercury (ii) oxide
(c)the number of the moles and the mass of the sodium nitrate nano3 required to produce 128 gram of oxygen (nano2 is the other product)
(d)the number of moles and the mass of the carbon dioxide formed by the combustion of 20.0 kg of carbon in excess of oxygen
(e)the number of moles and the mass of the copper(ii) carbonate needed to produce 1.500 kg of copper ii oxide (co2 is the other product)
