Answer: The percent yield for the is, 86.7 %
Explanation : Given,
Moles of = 2.36 mol
Moles of = 6.14 mol
First we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 2 moles of react to give 6 moles of
So, 2.36 moles of react to give
mole of
Now we have to calculate the percent yield for the .
Experimental yield = 6.14 moles
Theoretical yield = 7.08 moles
Now put all the given values in this formula, we get:
Therefore, the percent yield for the is, 86.7 %
1. The bar of metal is not pure gold.
2. The volume of 50.0 g of air is 42,016 mL.
3. The mass of the pure aluminum is 135 g.
4. The light beam's wavelength in meters is 475 x m.
The density of a substance is the ratio of the mass of the substance and its volume.
Density = mass/volume.
For the first problem: mass = 57.3 g, volume = 4.7 cm3
Density of the metal = 57.3/4.7
= 12.19 g/cm3
The density of gold is 19.3 g/cm3. Thus, the bar of metal is not pure gold.
For the second problem: density = 1.19 x g/ml, mass = 50.0 g
Volume = mass/density
= 50/1.19 x
= 42,016 ml
The volume of 50.0 g of air is 42,016 mL.
For the third problem: density = 2.70 g/ml, volume = 50.0 ml.
Mass = density x volume
= 2.70 x 50
= 135 g
The mass of the pure aluminum is 135 g.
Lastly:
nano =
475 nm = 475 x m
The light beam's wavelength in meters is 475 x m.

Taking into account the reaction stoichiometry, 340.0 moles of methane are produced when 85.1 moles of carbon dioxide gas react with excess hydrogen gas
<h3>Reaction stoichiometry</h3>In first place, the balanced reaction is:
CO₂ + 4 H₄ → CH₄ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- CO₂: 1 mole
- H₄: 4 moles
- CH₄: 1 mole
- H₂O: 2 moles
The following rule of three can be applied: if by reaction stoichiometry 1 mole of CO₂ form 4 moles of CH₄, 85.1 moles of CO₂ form how many moles of CH₄?
<u><em>moles of CH₄= 340.4 moles</em></u>
Then, 340.0 moles of methane are produced when 85.1 moles of carbon dioxide gas react with excess hydrogen gas
