Hey there!
Your answer is B. CO₂.
This molecule consists of two polar bonds, but they cancel each other out because they are pointing away from each other.
Because the forces of the bonds cancel out, the molecule itself is nonpolar.
Hope this helps!
Models help us to understand the properties of molecules and help us to predict the kind of reactions they undergo.
A molecular model is a three dimensional representation of a molecule. Usually, molecular models could either be;
- Ball and stick models or
- Space filling models.
In either case, the model gives us a vivid representation of the molecule and enables us to predict its properties and reactivity based on the the inter-connectivity of atoms in the structure as shown in the model. The model of H2SO4 as shown gives us an idea of its properties and its reactivity.

They are all biotic factors, meaning they were once alive or were alive. (an abiotic factor is something that has never lived.) hope this helped.
All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon. There are 118 elements, but only 92 occur naturally.

Explanation:
Given that,
Mass of metal cube, m = 20 g
Volume of cube, V =5 mL
We need to find the density of the cube. Mass per unit volume equals density.
So, the density of the cube is 4 g/ml.
We know that the density of Aluminium is 4 g/mL.
So, the cube is not Aluminium cube.
