Write the formulas for silicon dioxide.

Question

Note: it says formulas

SiO2 i guess is a formula but idk how to write formulas for it.

Answer 1

Simply reduce Si2O4 by dividing both subscripts by 2. That will get you SiO2. Silicon dioxide is held together by double, covalent bonds.

Si(s)+ 2O(g)=SiO2
