Answer:
3.38 moles of O2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
4CH2OH + 5O2 → 4CO2 + 6H2O
From the balanced equation above,
4 moles of CH2OH required 5 moles of O2 for complete combustion.
Finally, we shall determine the number of mole of O2 needed to react with 2.7 moles of CH2OH. This can be obtained as follow:
From the balanced equation above,
4 moles of CH2OH required 5 moles of O2 for complete combustion.
Therefore, 2.7 moles of CH2OH will require = (2.7 × 5)/4 = 3.38 moles of O2 for complete combustion.
Thus, 3.38 moles of O2 is required.
The formula for Hexafluoride is F6S.
Consumption is the answer
This balanced chemical equation shows the law of conversation of mas because it does not make matter nor destroy matter. If it is balanced, that means that no matter was created nor destroyed from the reactants to the products.
2h2o ----> 2h2 + o2
h=4 h=4
o=2 o=2
Since both sides of the equation are balanced/equal, that means that no matter was created nor destroyed, which demonstrates the law of conversation of mass. <span />
