Which substance is the limiting reactant when 18 g of sulfur reacts with 30 g of oxygen and 36 g of potassium hydroxide according to the following chemical equation?
2 S(s) + 3 O2(g) + 4 KOH(aq) - 2 K2SO4(aq) + 2 H2O(1)

O KOH(aq)
O2(g)
O K2SO4
O S(s)
O None of these substances is the limiting reactant.

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.
