2 H2S+302 ---> 2H2O +2 SO2
1) How many moles of O2 are used in this reaction?
2) What is the mole ratio of H2S to S02?

passing a magnet thought the

mixture , because iron gets attracted to magnet .

answer: mercury

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.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
