If 30.0 grams of calcium metal react with 18.0 grams of oxygen gas, your calculations show that ________ grams of CaO could be produced from the 30.0 grams of calcium and __________ grams of CaO could be produced from the 18.0 grams of oxygen. The theoretical yield of calcium oxide from this reaction is ________.

Answer:

42g if CaO can be produced from 30g and 31.5g of CaO will be produced from 18g of O

Explanation:

40g of CA =56g

30g =×

cross multiple

=56*30/40

=42g

32g of O =56g

18g =×

cross multiple

=56*18/32

=31.5g

theoretical yield

42-31.5= 10.5

just guessing
