Use of Halons
Halons are bromofluorocarbons that are used as fire extinguishers and pesticides. Halons produce bromine atoms by a similar process, causing the destruction of a very large number of ozone molecule..
Uses of Dihydrogen
Uses of Dihydrogen - It is used as a reducing agent in industry and laboratories. It is used to prepare hydrogenated vegetable oils. It is used for welding purposes in both the oxy-hydrogen torch and the atomic-hydrogen torch, when temperatures of t..
Abbreviations in powers of 10 (used in SI units)
.e., Le systeme internationale d' unites, is a new, comprehensive and rationalised system of units, accepted by the 11 t h conference of weights and measures in 1960. It is used in science and technology all over the world, because of the following advantages over others. The units are mo..
Applications
(i) Radioactive dating This gives us an approximate age of the rock or material containing the radioactive atoms. For e.g., A measurement of a fraction of uranium atom which have decayed into lead (by knowing the half life of uranium) tells us how old the rock is. (ii) Radiat..
Radioisotopes
A nuclide is any species of atom of which each atom has an identical proton number and also an identical nucleon number. Different nuclides, which have the same proton number (but different nucleon numbers) are called isotopes (isotopic nuclides..
Rule 1
When four different atoms are attached to the chiral carbon, priority depends on atomic number. The atom with the highest atomic number gets top priority. If the two atoms are isotopes of the same element, the atom of higher mas..
Sequence Rules
Rule 1 - When four different atoms are attached to the chiral carbon, priority depends on atomic number. The atom with the highest atomic number gets top priority. If the two atoms are isotopes of the same element, the atom of hi..
