When sulfuric acid reacts with sodium bicarbonate, carbon dioxide gas is released. If 2.0 L of CO2 gas is collected at standard temperature and pressure, how many grams of sodium bicarbonate we consumed? (use ideal gas law - R = 0.0821 l*atm/mol*k) H2So4 (aq) + 2NaHCO3 (aq) -> Na2SO4 (aq) + 2H2O (I) + 2CO3 (g) a) 7.5 g b) 8.7 g c) 3.9 g d) 4.7 g
When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete the lime absorbs CO, from the air and turns back into hard, durable limestone Suppose a limekiln of volume 350. L is pressurized with carbon dioxide gas to 5.60 atm, and heated to 1110. °C. When the amount of CO2 has...
