the 1st is extremely extra of a chemistry question. air pollutants is many times the oxides of Carbon or Sulfur. they are the products of combustion. Combustion is a chemical reaction which mixes Oxygen and gasoline. The byproduct is warmth yet will additionally contain CO2 and each each and every now and then SO2. those variety of byproducts react with water to variety acids. CO2 + H2O -> H2CO3 (carbonic acid. that's what makes each and every of the little bubbles in comfortable beverages) 2SO2 + O2 + 2H2O -> 2H2SO4 (sulfuric acid. It motives acid rain) Rain will react with the CO2 and SO2 that are gasses. They dissolve interior the rainwater to variety acids. that's how they are faraway from the ambience. SO2 is often generated via burning coal for the era of electrical energy. The coal can contain Sulfur, which types sulfur dioxide whilst it burns.Scrubbers bypass the exhaust from the furnace by way of an excellent mist of water. The water gets rid of the SO2 a similar way rain does. The acidified water can then be neutralized via including lime. that's how acid rain is prevented. the 2nd question is extra a math question. If the comet replaced into in orbit, it has an orbital era. The earth is often interior a similar place each and every 12 months, it is its era. 1607 - 1531 = seventy six 1683 - 1607 = seventy six The orbital era of the comet replaced into seventy six years. If it replaced into final seen in 1986 (Haley's comet?) it extremely is going to next be seen in 1986 + seventy six = 2062.

This would get better answers under geography/history...
I think one of them is Japan btw, oh and the question as the title would help to under geography/history
