Please type your <u>subject</u> in the <b>School Subject</b> box. Any other words, <u>including obscure abbreviations</u>, are likely to delay responses from a teacher who knows that subject well.

write the balanced equation:

CaO + 2HCl >> CaCl2 + H2O

Note then that it takes half as many moles of CaO as it does HCl.

Moles HCl: .275*.523

moles CaO: half that.

grams CaO: molesCaO*molmassCaO
