Which is the correct formula for phosphorus pentachloride? pcl4 because a subscript of 4 indicates four cl atoms pcl5 because a subscript of 5 indicates five cl atoms p5cl because a subscript of 5 indicates five p atoms p5cl3 because a subscript of 5 indicates five p atoms

The correct formula for phosphorous pentachloride is because a subscript 5 indicates five chlorine (Cl) atoms.

Explanation: For the given molecule, phosphorous pentachloride, there are 2 atoms present which are phosphorous and chlorine atoms.

Number of phosphorous atoms = 1

Number of chlorine atoms = 5

So, the correct formula for phosphorous pentachloride will be because the subscript 5 represents the 5 chlorine atoms.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
