Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

(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…

CONCLUSIONS: In general, the boiling points of compounds increase down a group in the periodic table. The melting points and boiling points for the hydrogen compounds of group 6A elements are in the table below. Melting Point (°C) Boiling Point (°C) H₂O 0.0 100.0 H₂S -82.0 -60.0 H₂Se -65.7 -41.2 H₂Te -49.0 -2.2 Use your understanding of chemistry to propose an explanation for the anomaly in the trend for the hydrogen compounds of group 6A elements shown in the table.
