Certain amounts of the hypothetical substances A2 and B are mixed in a 3.00 liter container at 300. K. When equilibrium is established for the reaction the following amounts are present: 0.200 mol of A2, 0.400 mol of B, 0.200 mol of D, and 0.100 mol of E. What is Kp, the equilibrium constant in terms of partial pressures, for this reaction

explanation:

i did this but i forgot how to do it

answersilicon (si); oxygen (o);

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
