Answer:
5.99 moles of
Explanation:
In this case, we can start with the <u>decomposition</u> of , so:
<u>(Reaction 1)</u>
The can react with carbon to produce
:
<u>(Reaction 2)</u>
If we 8.99 mol of , we can calculate the moles of
that we need. In reaction 2 we have a <u>molar ratio</u> of 1:2 (2 moles of
will produce 1 mol of
):
With this value and using the <u>molar ratio</u> in reaction 1 (3 moles of are producing by each mol of
), so:
So, we will need 5.99 moles of to produce 8.99 mol of
.
