At high temperatures and pressures, hydrogen sulfide gas reacts with oxygen gas to produce sulfur dioxide gas and water vapour. In an experiment, 0.8480g of oxygen was reacted with excess hydrogen
sulfide, and when the reaction was complete the percentage yield was 80%. Calculate how much sulfur
dioxide was recovered

answer; i do believe the correct answer is (river); /// good luck

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.
