This is a chemical change because there is a new substance that was created and the new chemical can cause other chemical reaction to happen compared to the 1st state of chemical that was in the cave. Because the cave water was exposed to another environment, the calcium bicarbonate, which is also known as salt. When the cave's groundwater was exposed to a different environment the atom in the cave water rearranged and crystallized.
I think the answer is False.
Water is made up of atoms bonded to form molecules, the chemical formula for water is H20, and 1 side has a positive charge, while the other has a negative one.
<h3>What is water?</h3>
Water is a fundamental molecule for life on the Earth due to its physico-chemical properties.
The water formula is H2O, which means that this molecule is composed of two atoms of Hydrogen and one atom of Oxygen.
In conclusion, Water is made up of atoms bonded to form molecules, the chemical formula for water is H20, and 1 side has a positive charge, while the other has a negative one.

Some physical properties that a pencil would have is, color, density, texture, hardness (in this case the lead is soft). phase (liquid,solid gas), shape, size. physical properties describe the look and feel of a substance. I hope this helps
