Suggest a name and formula for the substance represented in diagram D. Remember to write both name - _ and formula - _

Name- Carbon dioxide

Formula- CO₂

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.
