Answer:
SiO2(s) + 3C(s)  ------> SiC(s) + 2CO(g)
Explanation:
 The formula for silicon oxide is SiO2 and carbon is C. silicon carbide is SiC
 and carbon monoxide is CO.
An arrow is always used to separate the reactants (left) and products (right).
A balanced equation must contain equal number of atoms in each side of the equation. 
For example in the equation above, there are 1 atom of silicon appears on each side; 2 atoms of oxygen and three atoms of carbon.
