Question

The chemical formula of silicon oxide is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

To write the chemical formula of a compound. First, write down the symbols of the elements side by side that form the compound SiO. Under each symbol of the element, write down the combining power of the element. Remove the charge sign and interchange the combining power.

So the chemical formula of silicon dioxide will be $Si{O}_2$ as the combining power will be interchanged before interchanging the combining power of silicon and oxygen will be subtracted because the sum of the combining power must be zero. So, the chemical formula will be $Si{O}_2$.
