Question

1. choose the best answer.

the lewis structure for silicon dioxide (sio₂) contains how many double bonds?
0
1
2
3

Explanation:

Step1: Analyze the Lewis structure

In the given Lewis structure of $\ce{SiO_2}$ (as shown: $\ddot{\text{O}}=\text{Si}=\ddot{\text{O}}$), we look at the bonds between Si and O. A double bond is represented by "=".

Step2: Count the double bonds

We can see that there are two double bonds: one between Si and the left O, and one between Si and the right O. So we count these double bonds.

Answer:

2 (corresponding to the option "2" among the choices)
