1.	50. 0.5 mole of H,SO, is mixed with 0.2 mole of Ca (OH),. The maximum number of moles of CaSo, formed is(1) 0.2(2) 0.5(3)0.4(4) 1.5
Answer» Ca(OH)2+H2SO4→CaSO4+2H2OAsperthestochiometricequation,1moleofCa(OH)2reactswith1moleofH2SO4So0.2moleofCa(OH)2gives?moleofH2SO4=11×0.2=0.2moleofH2SO4ButtheamountofH2SO4givenis0.5mole.ThatmeansCa(OH)2actsasalimitingreagent.So1moleofCa(OH)2gives1moleofCaSO40.2moleofCa(OH)2gives=11×0.2=0.2moleofCaSO4
