Answer 1: The word “a” is categorized under indefinite articles because it is used to mention a singular noun that is unspecified.

Answer 2: Mercuric Oxide is a yellow to orange-yellow, odorless, crystalline powder. It is used in alkaline batteries and pigments, as a seed protectant, and as a preservative in cosmetics.

Answer 3 : When Bengal grams seeds are soaked in water the seed coat first absorbs water. It swells and becomes tender. This is followed by germination after some days in which radicle sprouts from the seed.

Spoilt seeds are eaten by insects or rodents. This creates holes in them hence they become light in weight and float.

Answer 4: Blowpipe, a small tubular instrument for directing a jet of air or other gas into a flame in order to concentrate and increase the flame's heat. A blowpipe is usually operated directly by mouth, but a small bellows may also be used.

Answer 5: Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
