A series of chemical reactions were carried out in a laboratory in the following way. At first zinc granules reacted withH_2SO_4 to form H_2 gas. Then hydrogen gas reacted with chlorine gas under diffused sunlight to form hydrogen chloride gas. Hydrogen chloride gas produced in this process was dissolved in water to form hydrochloric acid. Hydrochloric acid reacted with sodium hydroxide to form soruum chloride and water. Sodium chloride thus produced is first melted and then electricity is passed through it. Due to the passage of electricity through sodium chloride, sodium n1etal and chlorine gas is obtained. Rahul was asked to arr:mge the above reactions in the order of combination, decomposition, displacement and double decomposition. His answer is given below. (a) Formation of H_2 gas. (b) Formation of hydrogen chloride gas. (c) Formation of sodium and chlorine from sodium chloride. (d) Fomation of sodium chloride. Which among the following orders given below is correct, according to you?

Answer» c d b a b c a d a b c d b c d a Solution :`Zn+H_2SO_4toZnSO_4+H_2`, DISPLACEMENT reaction `H_2+Cl_2to2HCl`, combination reation `2NaClto2Na+Cl_2` decomposition reaction Hence the ORDER is b, c, a, d (i) Formation of hydrogen CHLORIDE gas. (ii)Formation of sodium and CHLORINE from sodium chloride. (iii)Formation of `H_2`gas. (iv)Formation of sodium chloride.
