Given the following equation, what is the correct form of the conversion factor needed to convert the number of moles of o₂ to the number of moles of fe₂o₃ produced? 4fe(s) + 3o₂ (g) 2fe₂o₃(s)

E

Explanation:

The question deals with the stoichiometry of the conversion of the number of moles of oxygen to the number of moles of iron III oxide.

Since three moles of oxygen yields two moles of iron III oxide according to the balanced reaction equation, it then follows that 3/2 moles of oxygen will give the number of moles of iron III oxide produced in the reaction. Hence the answer.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
