Cl₂
Explanation:
The gas with the highest molecular mass will be considered the heaviest of all of them.
To solve this problem, we must calculate the molecular mass of the given gases;
O₂ CH₄ CO₂ and Cl₂
O₂ molecular mass = 15.9998 x 2 = 32g/mol
CH₄ = 12 + 4(1) = 16g/mol
CO₂ = 12 + 2(16) = 44g/mol
Cl₂ = 2(35.5) = 71g/mol
The heaviest of the gases given is Cl₂ because it has the highest molar mass compared to other gases.

The current divides according to the resistance; more current in the lower resistance, less in the higher resistance. This is called “parallel branches” or paths. The voltage is the same for both (all) branches.
Water is deemed as a polar molecule because of the electrostatic attraction occurring between molecules. One major key characteristic of knowing polar molecules is knowing their atomic geometry. Now, we know that water has two hydrogens and one oxygen atom covalently bonded to each other. This means that they share electrons. However, this sharing is unequal because oxygen is more electronegative compared to hydrogen. So, the electrons tend to be nearer to the oxygen atom making it partially negative. On the other hand, the hydrogen would be partially positive. Polarity arises when there is an imbalance in the pull of electrostatic forces between individual atoms. If you look at the molecular geometry of water, its shape is bent. As a result, it creates a dipole moment which attracts solute to bond with water. In chemistry, the primary rule of solubility is that 'like dissolves like'. This means that polar solutes will dissolve in polar solvents. Similarly, nonpolar solutes will dissolve in nonpolar solvents.
B.
There is no covalent bonds in pure H2O. Only hydrogen
