Answer:
27.1 g of SiC are formed by the reaction
Explanation:
The silicium carbide is formed according to the reaction of Carbon and silicium dioxide. We also can produce carbon monoxide at the reaction.
The equation is:
SiO₂ + 3C → SiC + 2CO
According to the stoichiometry we can prodouce 1 mol of silicium carbide, from 3 moles of carbon so we may propose this rule of three:
3 moles of C can produce 1 mol of SiC
Then 2 moles of C, will produce ( 2 . 1) /3 = 0.666 moles of SiC
We conver the moles to mass (mol . molar mass) =
0.666 mol . 40.1 g / 1 mol = 26.7 g
