Answer:
Name- Carbon dioxide
Formula- CO₂
Step-by-step explanation:
From the diagram, the substance, although only three, try to occupy the entire volume of the container, therefore, the substance is a gas
There are three unknown atoms per molecule of the substance of which two are similar, X and Y, therefore, the empirical formula of the compound of the molecule is XY₂
The structure of the molecule is linear, therefore, the bonds tend to stay as far apart as possible, possibly to bring the repulsion of like charges to a minimum of which the gas is likely carbon dioxide CO₂ molecule
Therefore the name for the substance is carbon dioxide, and the formula is CO₂.
