Reaction B: sodium carbonate + hydrochloric acid → sodium chloride + carbon dioxide + water1 Na2CO3 (s) + 2 HCl (aq) → 2 NaCl (aq) + 1 CO2 (g) + 1 H2O (l)If 0.500 g of Na2CO3 and a slight excess of HCl react, how much NaCl will be produced? Using Cramer’s Rule, find the solution of the following simultaneous equations
x + 2y + 3z = – 5
3x + y – 3z = 4
– 3x + 4y + 7z = – 7
