What volume of carbon dioxide is formed from 42 g of sodium bicarbonate when: a) heating it, b) the action of an excess of acid on it.
| November 20, 2020 | education
heating it: 2NaHCO3 = CO2 + Na2CO3 + H2O n NaHCO3 = m \ M = 42 \ 84 = 0.5 n CO2 = 0.5: 2 = 0.25 V CO2 = n * Vm = 5.6
the action of excess acid on it: NaHCO3 + HCl = NaCl + H2O + CO2 n NaHCO3 = n CO2 = 0.5 V CO2 = 0.5 * 22.4 = 11.2 liters.
