Answer: When heated, calcium and hydroxide and ammonium chloride react to produce ammonia gas, water vapor, and solid calcium chloride. Suppose 5.00g of calcium hydroxide and 10.00g of ammonia chloride are mixed in a test tube and heated until no more ammonia is given off. The remaining material in the test tube has a mass of 10.27g. What total mass of ammonia and water vapor was produced in the reaction?
Explanation: First feel the backlash equating:
CaOH +2NH4Cl --> CaCl2 + 2H20 + 2NH3
Given the total bulk of the CaCl2 brand, we can calculate the number of blemishes;
10.27g CaCl2 / a hard bony structure in the jaws of vertebrates bulk of CaCl2 (40.078 + 2*35.45) =.09254 blemishes CaCl2 produced
From this number, we can use the stoichiometry of the beginning equating to reckon the number of blemishes of H2O and NH3produced;
.09254*2=.1851 blemishes NH3 created * a hard bony structure in the jaws of vertebrates bulk of NH3 =3.152g
.09254*2=.1851 spies H2O caused * bony object in mouth bulk of H2O =3.335g
So increase the bulk of the NH3 and H2O presented together to get a definitive bulk of 6.487g. Using important figures, the correct answer is 6.49g
Note** Be very cautious in your phrasing concerning this question and in what way or manner you concern your commodity. There is no aforementioned as"hydroxide," quite it has to lie as an affiliate with organization extraordinary, calcium hydroxide. It is hopeful absurd to just increase hydroxide to something.
