Answer:

What is the evidence of the chemical reaction you observed in the reaction of water and iron?

The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.

When carbon dioxide reacts with water, carbonic acid is formed, from which hydrogen ions dissociate, increasing the acidity of the system. Therefore, in addition to any greenhouse effect, anthropogenic carbon dioxide emissions to the atmosphere can increase the acidity of the atmosphere and precipitation.
