Which reaction below is a physical change? a. CH4​(g) + 2O2​(g) → CO2​(g) + 2Hs​O(l)
b. CaO(s) + H2​O(l)→ Ca(OH)2​(s)
c. H2​O (l) → H2​O(s)
D. 2Hs​O (l) → 2H2​(g) + O2​(l)

c. H₂​O (l) → H₂​O(s)

Explanation:

The correct answer is option C: The molecular formulas for the substance(s) on the left side of the equation and on the right side of the equation are identical. This means that there was not a chemical change, but a physical one.

In this concrete example, what happened was a change of states of matter: from liquid (l) to solid (s).

Other reactions have different molecular formulas on both sides of the equation, thus they represent chemical changes.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

is there any options? maybe im just not seeing them but i need the options to
