Can you help me balance equation?

Question

SiO2(s) +C(s) > Si(s)+CO(g)

Silicon Tetrachloride is reacted with very pure magnesium, producing silicon and magnesium chloride.

Na2SiF6(s) + Na(s) > Si(s) + NaF(s)

Answer 1

BALANCED:

1) SiO2(s) + 2C(s) > Si(s) + 2CO(g)

2) 2Na2SiF6(s) + 8Na(s) > 2Si(s) + 12NaF(s)

I think.
