1.) For the reaction, calculate how many grams of the product form when 18.4g of Ca completely reacts.
Assume that there is more than enough of the other reactant.
Ca(s)+Cl2(g)→CaCl2(s)

answer - 50.9 g.

2.) For the reaction, calculate how many grams of the product form when 18.4g of Br2 completely reacts.
Assume that there is more than enough of the other reactant.
2K(s)+Br2(l)→2KBr(s)

answer - ?

3.) For the reaction, calculate how many grams of the product form when 18.4g of O2 completely reacts.
Assume that there is more than enough of the other reactant.
4Cr(s)+3O2(g)→2Cr2O3(s)

answer - ?

4.) For the reaction, calculate how many grams of the product form when 18.4g of Sr completely reacts.
Assume that there is more than enough of the other reactant.
2Sr(s)+O2(g)→2SrO(s)

answer - ?
