In a reaction, 5.3 g of sodium
carbonate reacted with 6 g of
acetic acid. The products were
2.2 g of carbon dioxide, 0.9 g
water and 8.2 g of sodium acetat. Show that these observations are in agreement
with the law of conservation of
mass.
sodium carbonate + acetic acid
→ sodium acetate + carbon
dioxide + water
