Answer:
26.74g
Explanation:
The equation of the reaction is;
SIO₂ + 3C --> SiC +2CO
From the balanced equation, the relationship between SiC and C is;
3 mol of C produces 1 mol of SiC
Converting mol to mass using; Mass = moles * Molar mass
Mass of SiC = 1 mol * 40.11 g/mol = 40.11g
This means;
3 mol of C produces 40.11g of SiC
2 mol of C produces xg of SiC
3 = 40.11
2 = x
x = 2 * 40.11 / 3 = 26.74g
I would say 3.0 cause yeah yeah yeah yeah I’m iann Dior

<span>There are five main branches of chemistry including, physical, analytical, biochemistry, organic and inorganic chemistry. I would have to say that the answer to this question is none of the above. The answers given to this multiple choice question are some of the branches of biology. If the question asked for the branches of biology then the answer would be all of the above.</span>
