Answer:
Explanation:
n CaCO3 = mass / m.wt
= 500 /( 40 + 12 + 16x 3)
= 5 mole
n CaO = 5 moles ( from the balanced equation we have 1:1 moles )
mass of CaO = nCaO X m.wt
5 x( 40 +16 )
= 280 grams
I believe the answer you're looking for is B. It's Polluted. I hope this helps.
Answer:
just replace the 9 mole with 3.68 g of Al .
I think it will help you.
True because it actually formed I know
