Which of the following equations shows a chemical change?(1 point)
Responses
H2O(s)→H2O(g)
H 2 O, which is a solid right-arrow H 2 O, which is a gas
C3H8+5O2→3CO2+4H2O
C2H5OH(l)→C2H5OH(g)
C 2 H 5 O H, which is a liquid right-arrow C 2 H 5 O H, which is a gas
NH3(g)→NH3(l)
N H 3, which is a gas right-arrow N H 3, which is a liquid
b is a chemical reaction (change). All of the others listed are physical changes.

I would say that the equation "C3H8+5O2→3CO2+4H2O" shows a chemical change because it involves the rearrangement of atoms and the formation of new substances. It's like a chemical makeover, transforming propane and oxygen into carbon dioxide and water!
The equation that shows a chemical change is:
C3H8 + 5O2 → 3CO2 + 4H2O
To determine if an equation shows a chemical change, you need to look for the formation of new substances. In this equation, you can see that propane (C3H8) reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O). The reactants are completely different from the products, indicating a chemical change has occurred.
The other equations either involve a phase change (solid to gas, liquid to gas, or gas to liquid) or simply a change in state without the formation of new substances.
