The bracket just separate an atom or the ion and in the above it means there are two hydroxide molecules
so bracket function is just to separate ions and molecules
hope it helps
Answer:
When metals react they lose electrons.
Explanation:
An ion is defined as a molecule or atom made up of a different number of electrons and protons. This makes the electric charge of the molecule net, not neutral.
In other words, an ion is a molecule or atom that has a positive or negative electric charge, making it an atom whose electric charge is not neutral.
The characteristic property of a metallic atom is to lose one or more of its electrons to form a positive ion. That is, metals lose electrons and acquire a net positive charge, which is why they are electropositive.
Answer:
Nothing
Explanation:
Thermal energy and heat are mainly related because of the fact that the faster molecules move, the more heat is created. If molecules are vibrating slower, that means that there will be less energy, resulting in less heat. Say I am boiling water. As the temperature increases, the water molecules move faster. Once that water cools, the molecules will be moving really slowly. In conclusion, thermal energy and heat are related because of how fast or slow the molecules move, the more or less heat and energy will be produced. I hoped this helped!
Answer:
warming up the solution.
Explanation:
- A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution.
- Supersaturated solution is a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances.
- A saturated solution can become supersaturated when it is cooled.
- Also, we can form a saturated solution from a supersaturated solution via warming up the solution:
<em>The solubility of solid solutes in liquid solvents increases as the solvent is warmed up.</em>
