Statement: “Passionate about cooking and chemistry, a chef calculated that, to promote the proper rising of dough while baking a cake at 180 °C (453 K) and 1.00 atm, she would need to use enough chemical leavening to produce a gas volume of 4.00 L. To achieve this, she chose to use ammonium bicarbonate, a compound that, when heated, degrades into three distinct gases responsible for the dough rising. The decomposition of ammonium bicarbonate occurs according to the chemical equation shown, and under the baking conditions, its yield is 80%.”
