Calculate the kinetic energy (in joules) of a mole of water molecules traveling at 11.7 m/s.

Explanation:

1. The equation to calculate the kinetic energy is:

(Eq.1)

where, m=mass, v=velocity, k=kinetic energy

2. Find the mass of one mole of water, :

Atomic weight of H = 1

Atomic weight of O = 16

Molecular weight of = (2*1) + 16

Molecular weight of = 18

3. Convert the mass of from g to Kg:

3. Replace quantities in Eq.1:

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.

it's all four options.
