The balanced equation is
4Fe+3O₂⇒2Fe₂O₃
We know that the mole of Fe₂O₃ is 6, and since the ratio between oxygen and <span>Fe₂O₃ is 3:2, we can see that
3:2 = x:6 (3 oxygen moles can make 2 </span>Fe₂O₃ moles = x oxygen moles can make 6 <span>Fe₂O₃ moles)
</span><span>
Multiply outside and inside (3*6 , 2*x) and put them on opposing sides of the equation
2*x = 3*6
2x=18
x=9
Therefore 9 moles of oxygen is needed.

Percent yield is 108.3%
<u>Explanation:</u>
Percent yield is the ratio of experimental yield and the theoretical yield multiplied by 100.The expression for the percent yield is given as,
Percent yield = ![$\frac{actual yield}{theoretical yield}\times100](https://tex.z-dn.net/?f=%24%5Cfrac%7Bactual%20yield%7D%7Btheoretical%20yield%7D%5Ctimes100)
It is given that the experimental or actual yield is 3.9 g and the theoretical yield calculated using stoichiometry is 3.6 g, then the percent yield is calculated as,
Percent yield = ![$\frac{3.9}{3.6}\times100 = 108.3](https://tex.z-dn.net/?f=%24%5Cfrac%7B3.9%7D%7B3.6%7D%5Ctimes100%20%3D%20108.3)
So the percent yield is 108.3%.
Orbiting or revolving could fit the term
Answer:
34.23 grams H2O.
Explanation:
1 Mole of HCl produces 1 mole of water
So 1.9 moles producers 1.9 moles of water
= (2*1.008 + 16) * 1.9
= 18.016 * 1.9
= 34.23 grams H2O.
If the frequency of a wave increases, its energy will increase. While if the frequency of a wave decreases , its energy will decrease.
Hope this helps.
