(0-1) Activated carbon, also called activated carbon, is obtained by carbonization of organic matter, e.g.: wood, coal, peat. This process involves heating the organic substance in the absence of air, resulting in the enrichment of the substance in carbon (carbon content increases).Activated carbon is a porous material whose particles have a very large surface area. This makes it able to bind other substances on its surface. It is an example of adsorption, a phenomenon which is used to purify water and air mainly from organic compounds. Complete the sentences by underlining the correct phrases given in brackets so that true sentences are formed. The process of carbonization of organic substances is carried out under (aerobic / anaerobic) conditions. It leads to (decomposition / oxidation) of organic compounds. The adsorption phenomenon takes place (on / inside) the activated carbon. Activated carbon is used as a filter for water treatment, because the toxic substances in the water are (oxidized/decomposed/adsorbed) on the surface. Activated carbon is also used as a medicine for stomach poisoning, because it (releases healing / absorbs harmful) substances.

Carbon dioxide gas, CO2(g), is generated in the combustion of a sample of ethane (C2H6). This CO2 is all bubbled into aqueous barium hydroxide to be absorbed to produce 0.506 g of solid barium carbonate precipitate. How many grams of ethane (C2H6) were initially burned? The absorption-precipitation reaction is given by [CO2(g) + Ba(OH)2(aq)  BaCO3(s) + H2O(l)].
