4. Carborundum, Sic, is a hard
substance made by combining silicon
dioxide with coke (Q) as follows:
sio (3) -+- 3C($) — SiC(s) + 2Cold.
What mass in grams of Sic is formed
from the complete reaction of
2.00 mol of carbon?

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

it would be a gas formation

there are two significant figures.
