Answer

blur Balanced chemical equation for the reaction sulfuric acid and calcium hydroxide is to say they + Calon is - Casoy (s) + 24 molar mass of the Say - 98.079 g malt! moler mass of Calon - 14.093 gmail no of moles of Hy soy - mass of the Soy molar mass of H Soy - 43.) a 98.079 amel = 0.439mol no of moles of Calon), - mass of Ca ionly molar mass of the Soy 29. 4g . 74.043 g mai = 0.396 mol 1 I moe Hy Son reacts completely with capus - 1 mol 0.439 mol t say will react completely with Calota - Imol Xo-439 mol Imol =0.439 mol Thus the amount of calon given is less than required for completion of reaction. & is thus the limiting Leegant and it also decides the

Imol Calon yields Casay = 1 mol 1 0.396 calos, will yield casas - 0.396 mol molar mass of casoy = 136.14 g ma mass of casoy formed - 0.396 mol x 126-14 gmott - 14.09 Formula of Lissiting Reagent . Calong No of moles of excen Hy say = 0.439 mol - 0.396 mol - 0.043 mol и, Sou - р. 43 mg xa8 074 4 мес уухад, 1 кусом = 4.21g
