Question

Write balanced chemical equation for the following chemical reactions, with state symbols of the reactants and the products.

a) When dil. Sulphuric acid is poured over magnesium ribbon , hydrogen gas bubbles , magnesium sulphate enters into the solution

b) When potassium iodide solution is mixed with silver nitrate solution, insoluble silver iodide separates out from the solution and potassium nitrate remains in the solution

Answer 1

a) dil.$H_{2} SO_{4} +$ Mg -----> MgSO_{4} + H_{2}
b) KI + Ag(NO_{3})_{2} -----> KNO_{3} + AgI_{2}

Answer 2

b.) KI + AgNO3 AgI + KNO3

This is a self balanced equation.
