Answers
Answer:
As for the operation, in a reverberatory furnace, heat is generally passed over the hearth which consists the ore mixture. The main method of heat transfer is through the radiation from the refractory bricks present in the walls and the roof. Additional heating is supplied from the burner to the ore.
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
Carbon dioxide reacts with calcium hydroxide solution to produce a white precipitate of calcium carbonate. Limewater is a solution of calcium hydroxide. If carbon dioxide is bubbled through limewater, the limewater turns milky or cloudy white.
In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.
Magnesium burns in air to form Magnesium oxide (MgO). Take a moist red litmus paper and bring it in contact with the white ash of MgO. ... MgO is basic in nature.
