What weight of zinc and sulphuric acid will be required to produce enough hydrogen to reduce completely 8.5g of CuO to Cu? (Zn=65.3, Cu=63.5)

Determine the number of protons present in 5.6 L of a sample of oxygen gas at STP, containing ""^(16)O isotope only.

One of the reaction that takes place in producing steel from iron ore is the reduction of iron (II) oxide by carbon monoxide to give iron metal and CO_(2) . FeO(s)+CO(g)hArr Fe(s)+CO_(2)(g),K_(p)=0.265atm at 1050K. What are the equilibrium partial pressures of CO and CO_(2) at 1050K if the initial partial pressures are: p_(CO)=1.4 atm & p_(CO_(2))=0.80 atm?
