The reaction is highly exothermic. That is why different forms of coal are used as fuels the most important compounds of carbon are hydrocarbons.

Science Why do ionic compounds have high melting points? Question: Why do ionic compounds have high melting points? Ionic compounds An ionic bond is a bond.

Solution. Verified by Toppr. DNA (Deoxy ribonucieic acid ) and RNA (Ribonucleic acid) are two biologically important compounds that contain both oxygen and nitrogen. Oxygen is present in pentose sugar (Ribose in case of RNA and Deoxy ribose in case of DNA) and nitrogen is present in nitrogenous bases (purines and pyrimidine).

Question Question 2 (ii) Write down the names of compounds represented by the following formulae: (ii) CaCl2 Solution (ii) CaCl2 : Ca is the symbol for calcium and Cl2 is the symbol for chloride ion. From the chemical formula, it is evident that calcium is the cation and chloride is the anion. We know that the name of cation precedes the anion.

Each covalent compound is represented by a molecular formula, which gives the atomic symbol for each component element, in a prescribed order, accompanied by a subscript indicating the number of atoms of that element in the molecule. The subscript is written only if the number of atoms is greater than 1.
