Question

Silicon dioxide reacts with carbon to produce `SiC` and carbon monoxide. How do you write the balanced equation for this reaction?

Answer 1

`SiO_2(s) + 3C(s) rarr SiC(s) + 2CO(g)uarr`

Explanation:

The reaction is an redox reaction. I don't know how it is made industrially (though there is a substantial usage of `SiC`). I imagine this is a solid state reaction where materials are roasted on HIGH (approx. `1500` `""^@C`).
