( 2 points) How much potassium chloride is produced, in grams, from a reaction that started with of 3.00 g of KClO3? (Assume all the KClO3 decomposes, and make sure the equation is balanced!!!)
8. (2 points) Balance the following chemical equations. A) __ Na + __ O2 → __ Na2O
B) ___Na2SO4 + ___CaCl2 → ___ CaSO4 + __NaCl C)__Al2O3 →__Al+__O2
D) __NH3 +__CO2 +__H2O → __(NH4)2CO3
E) __N2 + __H2 →___NH3
9. (1 points) What is the Molar concentration of a sample that has 1.25 g of KBr in 250 mL?
KClO3 →
KCl + O2
