What do you notice is different about the arrangement of the H 2 O molecules in solid form compared to the arrangement of molecules in the other substances?

when the water is frozen, the molecules are tight and bunched together because its a solid. Although that the molecules seem to be tight, it does not meant that the molecules are not moving. The molecules in H 2 O solid form makes them move fast as in vibration. If the H 2 O was in liquid form, the molecules would be spread out and there would be plenty of room to move. But if the H 2 O is a gas, the molecules are even more loose that the liquid and they do whatever they choose to.

Explanation:

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.
