Final answer:
The total mass of ammonia and water vapor produced from the reaction of calcium hydroxide with ammonium chloride is calculated by subtracting the mass of the remaining solid from the initial mass of reactants. A typo in the given options makes it unclear which choice is correct, but by calculation, we find 13.73 g of gases were produced.
Step-by-step explanation:
When calcium hydroxide and ammonium chloride react, ammonia gas and water vapor are produced, along with solid calcium chloride. Given that 5.00 g of calcium hydroxide and 10.00 g of ammonium chloride yield a remaining mass of 1.27 g after the reaction, we can calculate the total mass of ammonia and water vapor produced. First, we calculate the initial total mass of reactants, which is 5.00 g + 10.00 g = 15.00 g.
After the reaction, the remaining mass is 1.27 g. The mass of the products that have escaped as gases can then be found by subtracting the remaining mass from the initial mass:
Mass of gases produced = Initial Mass - Remaining Mass = 15.00 g - 1.27 g = 13.73 g
Since the question appears to have a typo in the numbers provided in the options, the answer closest to the calculated 13.73 g is Option D) 7.27 g, which suggests the question may have intended to state the remaining material mass as something other than 1.27 g. Without the correct remaining material mass, we cannot definitively determine the correct choice.
