1.Calculate the number of mole of O2: 48/32=1.5 mol
2.Calculate the number of mole of H2 by mole ratio: 1.5 x 1/2=0.75 mol
3.Calculate the answer:
0.75 x 2=1.5g
Answer:
- The left side contains the reactants whose names are: iron (Fe) and oxygen (O₂).
Explanation:
The left side of the equation contains the reactants and the right side contains the products.
The chemical equation is:
Fe is the chemical symbol of iron. So, this part is iron.
O is the chemical symbol of oxygen. Since oxygen gas is a diatomic molecule the superscript 2 is used: O₂.
You can write the word equation to show the name of every partl on each side:
- iron + oxygen → iron(III) oxide.
Answer:
<em>Solution:</em>
Explanation:
V1 = 3.00m3
T1 = 150kPa
V2 = 1.20m3
T2 = x
As ,
<u> V1 </u> = <u>V2</u>
T1 T2
<u> 3.00</u> = <u>1.20</u>
150 X
3.00 x X = 150 x 1.20
3.00X = 180
X = <u>180</u>
3.00
<em>X = 60 kPa</em>
12+70= 82 g
(12/82)x100 = 14.6%
The answer is given to one decimal place.
