What is the chemical equation for aluminum and steam?
The chemical equation for the reaction between aluminum and steam is 2Al(s) + 3H2O(g) → Al2O3(s) + 3H2(g).
When water changes to steam is it a chemical change?
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply changing phase from a liquid to a gas, but the chemical composition of water remains the same.
Is steam chemical energy?
Steam is typically considered a form of thermal energy, as it is a vaporized form of water with high heat energy. However, if steam is used to power a turbine or generator to produce electricity, it can be considered a form of mechanical energy that is derived from the chemical energy stored in the fuel that heated the water to produce the steam.
Do steam and water contain the same chemical material?
Yes, steam and water both contain the same chemical material, which is H2O - two hydrogen atoms bonded to one oxygen atom. The difference lies in their physical state, with steam being the gaseous form of water.
What is the chemical formula of steam?
Oh, dude, you're asking me about steam? Like, seriously? Steam is just water vapor, so its chemical formula is H2O. You know, two hydrogen atoms and one oxygen atom hanging out together, doing their steamy thing.
Why iron is a chemical change when it oxides?
Because the transformation of iron in oxides is a chemical raection, an oxydation. A new compound (molecule) is formed.
When water turns into steam is it a chemical change?
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
How does the controlled variables affect the arte of raection?
how does the controlled varriables affect the rate of reaction
Is mixing popcorn steam a physical or chemical change?
it is a chemical change
Is water is heated and changed to steam a physical change or chemical change?
chemical
What is the chemical equation for aluminum and steam?
The chemical equation for the reaction between aluminum and steam is 2Al(s) + 3H2O(g) → Al2O3(s) + 3H2(g).
Why liquid water changing into steam is a physical not a chemical change?
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
Of a kettle boils and water turns to steam is it a chemical or physical reaction?
Its a chemical reaction :]
Is boiling water into steam is chemical change?
yes
Does Lead react with steam?
lead does not react with water or steam
Is heat changes h20 to steam a chemical change?
physical
Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
