PLEASE HURRY. compare the reactivitys of potassium and gold metals toward water, what happens when SO2 reacts with water?? write chemical

See Explanation

Explanation:

The reactivity of a metal towards water depends on the position of the metal in the electrochemical series. Metals that are high up in the series do react violently and spontaneously with water. Metals that are lower in the series are sometimes unreactive in water.

Hence, potassium reacts very rapidly with water to yield KOH and hydrogen gas while gold does not react with water.

SO2 react with water to form sulphuric acid hence SO2 is called an acid anhydride.

The reaction occurs in the following steps;

2SO2(g) + O2(g) >2SO3(g)

SO3(g) + H20(l) >H2SO4(aq)

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain
