Question

For each of the reactions, calculate the mass (in grams) of the product formed when 15.69 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 (in grams). 2K(s) + Br2(l) → 2KBr(s) Express your answer using four significant figures (in grams). 4Cr(s) + 3O2(g) → 2Cr2O3(s) Express your answer using four significant figures (in grams). 2Sr(s) + O2(g) → 2SrO(s) Express your answer using four significant figures (in grams).

Step 1

For the reaction 2K(s) + Cl2(g) → 2KCl(s), the molar mass of K (potassium) is approximately 39.10 g/mol. Therefore, the number of moles of K in 15.69 g is 15.69 g / 39.10 g/mol = 0.4010 mol. Since the reaction produces 2 moles of KCl for every 2 moles of K, the Show more…
