Number of moles of P₄O₁₀ in 852 grams = 852/284 = 3 moles
The balanced chemical reaction is;6 CaO + P₄O₁₀ > 2 Ca₃(PO₄)₂
6 moles of CaO reacts with 1 mole of P₄O₁₀ to give 2 moles of Ca₃(PO₄)₂.
But there are 3 moles of P₄O₁₀ present in the sample.
So, 18 moles of CaO reacts with 3 moles of P₄O₁₀ to give 6 moles of Ca₃(PO₄)₂.
Mass of 18 moles of CaO = 18 x 56 = 1008 gramsTherefore 1008 grams of CaO is required to react with 852 grams of P₄O₁₀.
hope it helps!!
it is a group of some atmos have tendency to change the physical and chemical characteristics of the compound in that functional group is added.
example- hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl etc.
