Answer: This may help you
Explanation:
1. Valency of carbon in C2H6 is.....
=> Valency of carbon in CH4 is 4 in C2H6 is 3.
2. Chemical formula of sulphurous acid is.....
=> Sulphurous acid is an acid having the chemical formula H2SO3. It is a covalent compound containing only covalent chemical bonds. The molar mass of sulphurous acid is 82.07 g/mol. Sulphurous acid is a weak acid and unstable. It is formed when sulphur dioxide (SO 2) is dissolved in water.
3. Latin name of Lead is....
=> Known as ( Pb ), lead’s scientific name and symbol are derived from the Latin word plumbum meaning “liquid silver.” A malleable, bluish-white metal with poor electrical conductivity, lead carries a molecular weight of 207.20.
4. Symbol of Ga stand for....
=> Symbol of Ga stand for Gallium.
The image reflects on puns relating to the origin of the element’s name. Lecoq de Boisbaudran named the element after France (‘Gaul’ in Latin) and also himself, since Lecoq, which means ‘the rooster’ translates to ‘Gallus’ in Latin. A silvery metallic rooster is shown on a background of an antique map of France.
Gallium is a soft, silvery-white metal, similar to aluminium.
5. .......is a measure of the kinetic energy or speed of the particle in substance.
=> Temperature is a measure of the kinetic energies of the particles in a substance. However, because the particles in a substance move at different speeds, the particles can have different amounts of kinetic energy. So, what does temperature actually measure? Temperature measures the average kinetic energy of the particles in a substance.
