Is hydrogen and oxygen combing into water a chemical change?
Yes, hydrogen and oxygen combining into water is a chemical change, represented by the following equation: 2H2 + O2 ---> 2H2O
Chemical equation for hydrogen to water vapor?
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
Is bolling water a chemical change?
No, it's a physical change, for you can change steam back to its original state, water
Is water evaporating a chemical change?
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
Why To balance a chemical equation can we change the formulae of either reactants or products?
if it is a redox reaction sometimes you can add water to help balance the equation
What does the state symbol mean when written after a chemical compound in a chemical equation?
it means the compound is dissolved in water.
Is hydrogen and oxygen combing into water a chemical change?
Yes, hydrogen and oxygen combining into water is a chemical change, represented by the following equation: 2H2 + O2 ---> 2H2O
What does the state symbol (aq) mean written after a chemical compound in a chemical equation?
it means the compound is dissolved in water.
What does the state symbol (aq) mean when written after a chemical compound in a chemical equation?
it means the compound is dissolved in water.
Is it physical or chemical when water freezes at 0 degree celsius?
When liquid water freezes to form ice, the chemical composition of water does not change. It will be H2O whether it is in liquid state or solid state. So it is a physical change and not a chemical change.
Is melting ice into water a chemical change?
No. It is a physical change. The chemical formula for water is H2O, and that is also the chemical formula for ice. So there is no chemical change taking place, only a change in the state of matter.

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
Difference between a pysical change and a chemical change?
Chemical change changes the electrons of matter, a physical change does not. Water is water as ice, water and steam, this is a change of state but physically there is no change of water it is a change of the energy content of water.
Is bolling water a chemical change?
No, it's a physical change, for you can change steam back to its original state, water
Is reactivity with water a physical or chemical change?
This is a physical change. The bubbles are pockets of steam which is the same chemical as water, just in a different state.
Is water evaporating a chemical change?
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
