To turn a regular glass of water into a healing drink, look for fast-dissolving magnesium sold as “molecular hydrogen tablets.” They are actually made of magnesium, but like a chemistry ...

After viewing a model of salt, students help develop models for the processes of salt dissolving, water evaporating to form a gas, and salt re-forming as a crystal. The focus is that matter, whether ...

Point out that a molecule of carbon dioxide has a slight negative charge near the oxygen and a slight positive charge near the carbon. CO 2 is soluble because water molecules are attracted to these ...

The gas will want to float into the air, so it’s hard to actually keep the hydrogen in the water; leaving it uncapped will allow the gas escape, much like carbon dioxide bubbles float away if ...

Hydrogen is a colorless, odorless, non-toxic gas that binds to other elements like oxygen, nitrogen, and carbon to form various compounds, including table sugar and water ().
