The burning of acetylene (c2h2) in oxygen is the reaction in the oxyacetylene torch. how much co2 is produced by burning 20.0kg of acetylene in an excess of o2? the unbalanced equation is: c2h2(g)+o2(> co2(g)+h2o(g)

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.
