a. A material that can exist as solid, liquid and gas.

ans: I,Br,Cl

Answer 2

Answer

Explanation:

Q1- Name the following:

(a) Water is the only common substance that is naturally found as a solid, liquid or gas.

(b) Homonuclear tetratomic molecules include arsenic (As4) and phosphorus (P4). Allotropes are different chemical forms of the same element (not containing any other element). In that sense, allotropes are all homonuclear.

(c) Acid radical is the ion formed after the removal of Hydrogen ion (H+) from an acid. Example: When H2SO4 loses H+ ion, it forms HSO4− which is an acid radical. The ion formed after the removal of hydroxide ion (OH−) from a base is known as basic radical. Acid radicals are formed by removal of hydrogen ion (H+). ...

Example: H2S04 loses one H+ ion to form HSO4– ion. Example: KOH loses OH– ion and becomes K+ ion.

(d) The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products.
