Is There Something Wrong? Trivia Quiz

Answer: Yes

An electron is approximately 1/1840 the mass of a proton as well as of a neutron. Thus the mass of an atom is concentrated in its protons and neutrons i.e. the nucleus. An electron is negatively charged, a proton is positively charged while a neutron carries no charge.

Answer: Yes, salt isn't the right substance - it should be an alkali

An alkali is a substance that gives hydroxyl ion as the only negatively charged ion on dissolving in water. Acid is a substance that gives hydronium ion as the only positively charged ion on dissolving in water. Salt is a substance formed as the product when an acid reacts with a base. Alkali will be the appropriate answer as alkalis are soluble in water and not all bases are.

Answer: Yes

Avogadro's Law and Gay Lussac's Law form the backbone of Mole Concept. This law was formulated by Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto after Gay-Lussac's Law of combining atoms was published in 1808. Mole Concept is very helpful in finding volumes, masses and the amount of substance present in a particular compound. One mole is the amount of substance which contains particles equal to 6.023 * 10^23 which is called Avogadro's number.

Answer: They are organic acids

Acetic acid is commonly called vinegar. Formic acid is found in the sting of bees and ants. Since they are derived from organic resources, they are called organic acids. Acids like hydrochloric acid, nitric acid and sulphuric acid are mineral acids or inorganic acids.

Answer: Yes

Hydrogen sulfide has a foul odour similar to that of rotten eggs. It is very corrosive and poisonous in nature. It has various uses such as in qualitative inorganic analysis and in the production of thioorganic compounds to mention just two of its applications.

Answer: Ammonium nitrate, on heating, liberates laughing gas

Ammonium nitrate, on heating, liberates nitrous oxide gas. Sodium and potassium nitrate, on heating, liberate oxygen gas. All other nitrates, on heating, liberate reddish brown nitrogen dioxide gas and oxygen.

Answer: Ammonia is prepared in industries by the Haber's process

Ammonia is prepared in industries by the Haber's process while nitric acid is prepared in industries by the Ostwald's process. Artificial silk from ammonia is prepared in industries by the cupro ammonium process and baking soda (NaHCO3) is prepared by the Solvay process.

Answer: Yes

If an atom or an ion loses an electron, then it is said to be oxidized. An atom or an ion is said to be reduced if it gains electrons. For example, if an atom of iron loses one electron to form a cation, then it is said to be oxidized. But if the cation gains one electron to become neutral, then it is said to be reduced.

Answer: no

Water(H2O) is a polar covalent molecule. Two hydrogen and one oxygen share two electrons to form the molecule.

Answer: Yes

The acid present in your stomach is hydrochloric acid (HCl). It can be prepared by synthesis of moisturized hydrogen and chlorine in diffused sunlight. The reaction is explosive if the mixture is exposed to direct sunlight.
