Mg(s) + H2SO4(aq) ==> MgSO4(aq) + H2(g) + heat
Reaction is spontaneous and highly exothermic(heat is liberated).
Production of hydrogen gas takes place which can be acertained when you light a matchstick over the test tube and Hydrogen gas evolved makes it burn brightly!

A) is the perfect answer. The pH of the reaction might want to develop into better effectual turning out to be from a low variety to a better cost. right it truly is why. Mg + H2 SO4 = Mg SO4 + H2 (g) The hydrogen ion which makes the answer an acid is removed from the answer and given off as a gas. With a lot less hydrogen ion cutting-edge, the answer's way less acid and has a better pH cost.

any reaction between a metal and an acid will give salt and hydrogen and in the reaction between magnesium and sulphuric acid will give magnesium sulphate and hydrogen
hope u benefit
