If water is H2O then what is ice?

Question

would it be like H2O2? because ice seems to have more oxygen in it than normal water? that is why it expands right?

Answer 1

It's still H2O

Ice doesn't have more oxygen than water, and it doesn't expand.

You know how things have a freezing and melting point right? That's all it is. You don't add any oxygen to it when you put water in a low temperature.

Hope this helped! :)

Answer 2

Ice remains H2O (as ice is water in solid form). The reason that ice water expands is not due to a change in the molecule composition BUT the geometry of the crystals of solid water. They form hexagonal structures that allows the formation of "empty spaces" that are responsibles of the dilation in that physical state.

Answer 3

Ice is frozen water.  It's still H2O.

H2O2 is an entirely different compound called hydrogen peroxide.

Water expands as it freezes because it crystallizes into an open framework of water molecules that occupy more space than the molecules did as a liquid.

Answer 4

Ice is solid H2O

Water is a peculiar compound in that it is more dense just above freezing than at freezing.  This is due to the way the hydrogens and oxygens align with each other, pushing the molecules slightly further apart when it goes solid.

Answer 5

The chemical name for ice is also H20.  

Answer 6

Ice is also H2O. The physical state for ice is solid whereas for water it is liquid? but same molecule

Answer 7

It is still the same chemical compound. Therefore it is H2O.
