The formula of ionic compound made from sodium (Na) and iodine (l) is
NaI
<em><u>Explanation</u></em>
- An ionic compound is are compounds made up of ions.
- The ions are atoms or ions that loses electron to form cation or gain electron to form anion.
- Metal for this case loses electron while non metal gain electrons
- In Nal Na <em>( a Metal</em>) loses one electron while I <em>(non metal) </em>gain one electron to form an ionic compound.
<span> I would guess that calcium (Ca), of all the group 2 elements, is most like magnesium (Mg), because it has the most similar size (atomic and ionic radii) to Mg. </span>
Answer: The volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
