Ans : The chemical equation in which the number of atoms of each element on both the sides are equal is called the balanced equation. A chemical equation should be balanced because there is no loss or gain of any matter during a chemical reaction, i.e., the law of conservation of matter must hold good for the reaction. Q 13.

Reaction of acids 1. Acid reactions with metals. Acids react with metals to produce a salt and hydrogen. acid + metal → salt + hydrogen. Example: hydrochloric acid + magnesium → magnesium ...
MgCl 2 (aq) + 2NaHCO 3 (aq) → MgCO 3 (s) + 2NaCl (aq) + H 2 O (l) + CO 2 (g) If magnesium chloride (or sulfate) is treated with aqueous sodium carbonate, a precipitate of basic magnesium carbonate—a hydrated complex of magnesium carbonate and magnesium hydroxide —rather than magnesium carbonate itself is formed:
Both magnesium hydroxide and calcium carbonate have a short, rapid effect; aluminum hydroxide has a slow, persistent effect. Administration of antacid medications poses difficulties in veterinary patients because of the high volume and frequency of treatment required to prevent rebound acid secretion.
magnesium carbonate + hydrochloric acid ---> magnesium chloride + water + carbon dioxide. MgCO3 + 2HCl ---> MgCl2 + H2O + CO2. 0 0 1.
The chemical equation for the reaction of sodium carbonate and hydrochloric acid is given as: Ionic form of the above equation follows: As, sodium and chloride ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions. The net ionic equation for the above reaction follows:
The reaction between magnesium metal and a dilute acid can be followed in a similar way noting the time taken for the bubbles of hydrogen gas to stop forming or for the magnesium metal to disappear. See also how the rate of this reaction is affected by increasing the concentration of the solution.
Magnesium carbonate is a base and nitric acid is, obviously, an acid so the reaction will be an acid-base reaction and such always results in the formation of a salt and possibly other products.
Carbonate : Regular high doses may cause alkalosis, which in turn may result in altered excretion of other drugs, and kidney stones. A chemical reaction between the carbonate and hydrochloric acid may produce carbon dioxide gas. This causes gastric distension which may not be well tolerated.
Zinc oxide is an inorganic chemical compound that is used as the main ingredient in preparing drugs or other medicines. It can be used as pigment or semiconductors in industries. The chemical formula for the compound could be written as ZnO with a molecular mass of approx. 81.379 g mol-1.

  • 4. How do you identify carbonate salt? Ans: Strong acids, such as hydrochloric acid, can be added to assess whether a mineral or rock contains calcium carbonate. If the sample contains calcium carbonate, carbon dioxide will be fizzed and produced. 5. What is the formula for calcium carbonate? Ans: The formula for calcium carbonate is CaCO 3.
