Question

What is the chemical formula of melting ice?

Answer 1

Hint: Water can exist in three different phases i.e.., solid, liquid and vapor. The chemical formula of water is the same in three different phases, but the phase can be represented differently. The first letter of the phase can be represented in brackets to the subscript of the chemical formula of water.

Complete answer:
Water is the chemical compound consisting of one oxygen atom and two hydrogen atoms.
The chemical formula of water is \[{H_2}O\] , it can exist in three different phases namely solid, liquid and water.
The water that existed in the solid phase can be called ice.
The water that existed in the liquid phase can be called water only.
The water that existed in the vapor phase can be called water vapor.
The ice chemical formula can be represented by \[{H_2}{O_{\left( s \right)}}\]
The chemical formula of water can be represented by \[{H_2}{O_{\left( l \right)}}\]
The chemical formula of water vapor can be represented by \[{H_2}{O_{\left( g \right)}}\]
Melting is the process of converting the solid phase to liquid phase.
Ice is in the solid phase; it melts to water which is in the liquid phase. This process can be termed as melting of ice.
The chemical formula of melting ice can be represented as below:
\[{H_2}{O_{\left( s \right)}} \to {H_2}{O_{\left( l \right)}}\]
Thus, the above equation represents the melting of water which is present in solid state to the water which is in liquid state.

Note:
The water can exist in three different physical forms. The conversion of water from one phase to another phase can be defined differently. Melting is the process of conversion of ice or snow i.e.., in solid state to water which is a liquid state.
