For each of the reactions, calculate the mass (in grams) of the product formed when 15.00 g of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant. 2K(s)+Cl2(g)––––––→2KCl(s)
Express your answer using four significant figures.

2K(s)+Br2(l)––––––→2KBr(s)
Express your answer using four significant figures.

4Cr(s)+3O2(g)––––––→2Cr2O3(s)
Express your answer using four significant figures.

2Sr(s)–––––+O2(g)→2SrO(s)
Express your answer using four significant figures.
