When coal is burned, sulfur is released into the air, where it reacts with oxygen to produce sulfur dioxide and sulfur trioxide. Which of these is true of this process? A. The identity of each reactant remains the same. B. Sulfur dioxide and sulfur trioxide are the reactants in this change. C. The products have different chemical properties than those of the reactants. D. The products contain more sulfur atoms and fewer oxygen atoms than the reactants.

Which of the following reaction produces SO2 gas?Burning of sulphur in oxygenReaction of copper with H2SO4Roasting of sulphide oresBurning of H2S

Most of the coal available in the United States is bituminous or "soft" coal, which contains as much as 5% sulfur by weight. When this coal is burned, the sulfur reacts with oxygen to form sulfur dioxide gas. When the sulfur dioxide gas dissolves in raindrops, it forms sulfuric acid. This is how we get acid rain. Here is the reaction that produces sulfur dioxide gas when soft coal is burned:S8s+8O2g→  8SO2gSuppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels with 133.1g of solid sulfur and 47.2g of oxygen gas each. The volume and temperature of each vessel is shown in the table below.Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on.vessel volume temperature initial rate of reactionA 5.0L 660.°C B 2.0L 670.°C C 3.0L 670.°C D 3.0L 660.°C

Which of the following is NOT produced by burning coal?a.CO2b.Ozonec.NOxd.SO2

Context: Fossil fuels are nonrenewable resources because they took millions of years to attain their present form.We use fossil fuels such as coal, oil, and gas to heat our houses, run industry, and transport. They are usually hydrocarbons (compounds of carbon and hydrogen). When they are burnt, they combine with oxygen from the air. The carbon becomes carbon dioxide; hydrogen becomes hydrogen oxide called water; while energy is released as heat. In the case of coal:Carbon + Oxygen      →→  carbon dioxide + heat energyHydrocarbon + Oxygen    →→   carbon dioxide + water + heat energy

When coal and petroleum are burnt in sufficient supply of oxygen, then ‘X’, water and oxides of ‘Y’ and ‘Z’ are produced. Identify ‘X’, ‘Y’ and ‘Z’.
