H2O (g) as it is water but just a gas Ice would be similar but just with a change of state symbol,
Correction - water vapour/steam has the chemical formula of 7H20 , and it water has never been broken down to H20 although it is generally assumed
The chemical equation for the combustion of fossil fuels, like gasoline, can be represented by CxHy + O2 -> CO2 + H2O. This equation shows that when fossil fuels are burned, they react with oxygen to produce carbon dioxide and water vapor.
Water vapor is in the gaseous state.
The chemical equation for burning propane in a grill is: C3H8 + 5 O2 → 3 CO2 + 4 H2O. This equation represents the combustion of propane, where propane (C3H8) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water vapor (H2O) as products.
A phase change is not a chemical change since the chemical remains the same; water is still water, whether it is in the solid, liquid, or gas phase.
The balanced chemical equation for a burned candle is C25H52 (wax) + O2 (oxygen) -> CO2 (carbon dioxide) + H2O (water) + heat. This represents the combustion reaction that occurs when a candle burns, turning the wax and oxygen into carbon dioxide, water vapor, and releasing heat.
The chemical equation for hydrogen to water vapor is not possible as stated. In order for hydrogen to form water in any physical state, it must combine with oxygen. The following are the word equation and the chemical equation for hydrogen and oxygen combining to form water. Hydrogen gas plus oxygen gas produces water. 2H2 + O2 --> 2H2O
It is still H20 if it is ice, water, or steam.
The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.
The chemical equation for the combustion of fossil fuels, like gasoline, can be represented by CxHy + O2 -> CO2 + H2O. This equation shows that when fossil fuels are burned, they react with oxygen to produce carbon dioxide and water vapor.
Water vapor is in the gaseous state.
No, this is definitely a physical change, absolutely not a chemical.

It is physical, change of state, just cooling down
The chemical formula (not equation) of water is H2O.
What is the chemical equiation for water
When water changes to water vapor, it has changed its state from liquid to vapor and no chemical change has taken place. It's only a physical change.
