1. 185 grams of iron (ii) oxide were reacted with 38.0 grams of aluminum as follows: 3 feo(s) + 2 al(s) → al2o3(s) + 3 fe(g) a) what was the limiting reactant? b) how many grams of total product (al2o3 + fe) formed if the reaction goes to completion? c) the total mass of the reactants is 223 grams. however, this is not the total mass of the products. why not? d) if the actual yield of the iron is 105.0 grams, what is the percent yield of iron?

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
