The chemical formula of the ionic compound is XY₂.
<h3>Ionic compounds</h3>
- Ionic compounds are compounds which are formed from the combination of negatively charged and positively charged ion.
- Positively charged ions are formed by loss of electrons
- Negatively-charged ions are formed from gain of electrons
<h3>Formation of ionic compounds</h3>
During the formation of the ionic compound between an ion X that has a charge of 2+ and ion Y has a charge of 1-, two negatively charged ions of Y are required to form a neutral ionic ionic compound when they react with X.
The chemical the formula of the ionic compound they form is as follows;
X²⁺ + 2Y⁻ ---> XY₂
Therefore, the chemical formula of the ionic compound is XY₂.

Answer:
D
Explanation:
Because the number of protons is the same as the atomic number, we know what the number of protons has to be 26. The mass number, 55, is the same as the number of protons plus neutrons. Lastly, because there is no charge on this atom, the number of electrons would have to be the same as the number of protons, which is 26.
Answer:
B carbon
Explanation
Lewis structure or dot structure is an easy way to get the bonding details of atoms in a molecule. If we talk about methane molecule carbon is central atom with four electrons that are bonded to four hydrogen atoms and each bond is single covalent bond.

How to calcutate concentration of solution.
there is 12gram of solute in a 36 gram solution
then you take 12 divided by 24 because 36-12=24 which is youe solvent
Answer: 165.6grams
Explanation:
Mass of a block = ?
Volume of block = 18 cm^3
Density of block = 9.2 g/cm^3
The density of any object depends on its mass and volume.
i.e Density of block = Mass / volume
9.2 g/cm^3 = Mass / 18 cm^3
Mass = 9.2 g/cm^3 x 18 cm^3
= 165.6 g
Thus, the mass of the block is 165.6grams
