Example #1 write the chemical formula for Calcium Oxide
Step 1
-Find the Atomic symbol of the metal and non-metal on the periodic table
CaO
Step 2
Find the charges for Calcium and Oxygen
which are Ca 2+ and O 2-
Step 3
Balance out the charges
They are already balanced out
Here´s the chemical formula for Calcium Oxide
CaO
Example 2 write the chemical formula for Aluminum Oxide
Step 1
-Find the Atomic symbol of the metal and non-metal on the periodic table
A
l
O
Step 2
Find the charges for Aluminum and Oxygen
Which are Al 3+ and O 2-
Step 3
Balance out the charges
You need 2 Aluminum and 3 Oxygen to balance the charges
Al 3+ O 2-
Al 3+ O 2-
= 6 + O 2-
= 6-
Step 4
If you need more then one element to balance out the charges you identify that by using subscripts
Heres your chemical formula for Aluminum Oxide
The answer is b because as the air gets cooler and the moist in the air will drop as we call it dew
Answer:
I. dissolving more solute in an unsaturated solution
Explanation:
A saturated solution is the solution which contains maximum concentration of solute dissolved in solvent.
However, if the solution is being provided with energy (heating) , it will dissolve more heat and the solution that cannot even dissolve more solute after heating is super saturated solution.
<u>Both saturated and supersaturated solutions have maximum of their capacity to dissolve the solute and hence further energy requires energy and these processes are non-spontaneous.</u>
<u>An unsaturated solution can dissolve more solute easily and thus is a spontaneous process.</u>

The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.
<h3>Why is the energy released in a reaction?</h3>
Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.
The quantity of energy released in reactions differs according to the reaction type involved.
When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.
The energy, E released in nuclear reactions is given by the formula below:
where m is the mass of the substance and c is the speed of light.
Therefore, the energy released in nuclear reactions are far larger than that released in chemical reactions.
