Rainwater absorbs atmospheric CO2, becoming carbonic acid.
This flows through the discontinuities in the rock from sink to rising, dissolving the calcium carbonate that is limestone's main constituent.
When acid rain comes into contact with limestone, it produces carbon dioxide gas. This occurs due to a chemical reaction that dissolves the limestone, releasing carbon dioxide into the atmosphere.
When limestone undergoes metamorphism, it produces the metamorphic rock called marble. This process involves recrystallization of the calcite mineral in limestone to form interlocking crystals of calcite in marble.
The chemical equation representing this reaction is 2Na + 2H2O → 2NaOH + H2.
The chemical equation for the reaction aluminum underwent in the disaster is 4Al + 3O2 -> 2Al2O3. This reaction produces aluminum oxide (Al2O3) when aluminum (Al) reacts with oxygen (O2) in the air.
The reaction between hydrogen gas and oxygen gas produces water as a byproduct. This is known as a combustion reaction. The balanced chemical equation for this reaction is: 2H2(g) + O2(g) -> 2H2O(l).
The symbol "->" (arrow) is used in a chemical equation to indicate produces or yields.

When acid rain comes into contact with limestone, it produces carbon dioxide gas. This occurs due to a chemical reaction that dissolves the limestone, releasing carbon dioxide into the atmosphere.
When limestone reacts with acid, it undergoes a chemical reaction that produces carbon dioxide gas, water, and a salt. This reaction is called neutralization and can be represented by the equation: CaCO3 + 2HCl -> CO2 + H2O + CaCl2.

A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
The chemical equation for the reaction between calcium and hydrochloric acid is: Ca + 2HCl -> CaCl2 + H2. This reaction produces calcium chloride and hydrogen gas.
