when hydrogen and oxygen combine then they form water as product
also in neutralization reaction water form as product
hope it helps
The number of grams of Ca) needed to produce 42.0 g of Hg is calciulated as below
4 HgS + 4CaO = 4 Hg + 3 Cas +CaSO4
calculate the moles of Hg produced
moles=mass/molar mass
moles of Hg = 42 g/200.59 g/mole = 0.2094 moles
by use of mole ratio of Cao:Hg which is 4:4 the moles of CaO = 0.2094 x4/4 =0.2094 moles
mass of CaO=moles x molar mass of CaO
mass of caO=0.2094 x56 = 11.73 grams
