Question

KIIS. Q. 2. Read the given passage and answer the following questions. The physical states of the reactants and products can be represented by using the symbols, (s) for solids, (l) for liquids, (g) for gases and (aq) for aqueous solution along with their respective formulae. The word aqueous is written if the reactant or product is present as a solution in water. Precipitate can also be represented by using an arrow pointing downwards (1) instead of using symbol (s)- In the same way, the gaseous state of an evolved gas can be represented by using an arrow pointing upward direction (1) instead of using symbol (g). The specific condition of the reaction like temperature, pressure, catalyst etc. is written above or below the arrow in the chemical equation. (a) Write the balanced chemical equation with state symbols for the given reaction: Magnesium reacting with dilute sulphuric acid (b) To indicate the presence of gaseous reactant or product, we use symbol (1) (c) Complete the missing variable given as X and Y in the following reaction: (1) 2Na (s) + 2H20 (1) 2NaOH(X) + H2 (Y) (d) Which of the following reaction is balanced? (i) 2NaCl + 2H2O → 2NaOH + 2Cl2 + H2 (ii) Ca(OH)2 + Cl2 → CaoCl2 + H2O (1) or (1)​
