Chemistry is Fun Trivia Quiz

Answer: Methyl alcohol

Whenever there is a reaction between an acid and a base, the product is always a salt of corresponding metal and water. Methyl alcohol is not a salt but an alcohol so it cannot be a product of a reaction between an acid and a base. Sodium chloride and potassium iodide are salts.

Answer: False

Sodium is a very reactive metal. It readily reacts with water to form sodium hydroxide and produces a lot of heat. It even reacts with oxygen in air to form its oxide with lots of heat. Its atomic number is 11 and its atomic symbol is Na.

Answer: 7

Dihydrogen monoxide is another name for water. Water's chemical formula is H2O. It is a neutral liquid so its pH is 7. Any pH less than 7 indicates that the given substance is acidic and for pH greater than 7 it's basic.

Answer: Boron

Boron is solid at room temperature. It is a semi-metalic solid with a boiling point of 3660 degrees Celsius. Its atomic number is 5. All other elements in above options are gases in the conditions stated.

Answer: Carbon

Carbon is a non metal. It can form long chains by combining with other carbon atoms to form various compounds. Francium is a radioactive metal. Lead is a heavy metal used in nuclear power plants. Mercury is a liquid metal which is used in thermometers.

Answer: Dolomite

Dolomite is an ore of magnesium. Bornite(Cu5FeS4), covellite(CuS) and chalcopyrite (CuFeS4) are ores of copper. Copper is a brownish yellow coloured metal. It is ductile hence used in making conducting wires. It is a good conductor of heat, so is used in making various utensils.

Answer: Carbonic acid

Strong acids are acids which completely ionize in water. Sulphuric, nitric and hydrochloric are strong acids. Carbonic acid is a weak acid. You can find this acid in your soda bottles.

Answer: Gold

Gold is a noble metal which means it will not react with any pure acid or base or any gas under any circumstances. Iron, zinc and aluminium are reactive metal hence will react with sulphuric acid to form corresponding sulphides. If sulphuric acid is mixed with nitric acid in the correct proportions, then this mixture has the potential to dissolve gold.

Answer: Zirconium

Zirconium is a metal which burns in both oxygen and nitrogen. The atomic number of this metal is 40. This metal has the special ability to absorb neutrons so it is used in nuclear reactors.

Answer: Helium

Helium is a very light and non reactive gas. For scuba diving, generally helium is mixed with oxygen to breathe. Oxygen is required for respiration while helium provides buoyancy to the diver. Nitrogen is also used with these two gases due to its low reactivity and it prevents air from becoming toxic at high pressure.
