Write a chemical equation that shows how acid rain H2SO3 was produced from SO2 gas and water in a zip sealed bag? My chem. teacher never explained how to do this and I have several other questions on this type of subject. If you could help me out it would help me tremendously! Thanks!

Outside of not knowing how the SO2 came into contact with H2O if the H2O was in a sealed zip lock bag, the equation between SO2 and H2O is

H2O + SO2 ==> H2SO3.

Certainly! I'd be happy to help you out with your chemistry question. To write a chemical equation that shows how acid rain, H2SO3, is produced from SO2 gas and water, we need to understand the reaction between these two substances.

The chemical equation is as follows:

SO2 + H2O -> H2SO3

Now, let's break it down step by step:

1. Start by identifying the reactants: SO2 (sulfur dioxide) and H2O (water).

2. Determine the products formed. In this case, H2SO3 (sulfurous acid) is produced.

3. Next, balance the equation. This means ensuring that there is an equal number of atoms of each element on both sides of the equation.

a. The equation currently has one sulfur atom (S) on both sides, which is balanced.
b. The equation currently has two oxygen atoms (O) on the left side (SO2) and three oxygen atoms on the right side (H2SO3). To balance the equation, add a coefficient of 3/2 in front of SO2:

3/2 SO2 + H2O -> H2SO3

4. Finally, check that the equation is balanced.
a. The left side of the equation now has three oxygen atoms from SO2 and one oxygen atom from H2O, totaling four oxygen atoms.
b. The right side of the equation has two oxygen atoms from H2SO3.

So, the balanced equation for the production of acid rain H2SO3 from SO2 gas and water is:

3/2 SO2 + H2O -> H2SO3
