The answer is: A molecule with a difference in electrical charge between two ends.
Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
For example fluorine has electronegativity approximately χ = 4 and oxygen χ = 3,5, fluorine attracts electron and he has negative charge and oxygen has positive charge.
The calculation for such a question can be achieved via Avogadro hypothesis
We know molar mass of CO2 is 44g/mole which is the sum of atomic masses i.e; C and 2 oxygen atoms
Molar mass of CO2 =12(C)+2*16(O) = 44 g/mole will contain 6.023 ※10^23 CO2 molecules ..
44g/mole = 6.023 ※10^23 CO2 molecules
=> 1g = (6.023/44) ※10^23 CO2 molecules
==> 8.80g = 8.80(6.023÷44)10^23 = 1.2046 ※10^23 molecules of CO2….
Thus there r 1.2046 ※10^23 molecules of CO2 in 8.80g
if u need to calculate no. of carbon atoms then multiply result by 1 and if u need no of oxygen atoms in 8.80g of co2 then multiply the result by 2 ….

Answer: The name given to 
is Gallium (III) sulfate.
Explanation: This is an ionic compound because in aqueous solution it dissociates into its respective ions.
Naming of Ionic compounds.
- Name the cation first and then write its oxidation number in roman numerical.
- Then name the anion or polyatomic ions without writing any prefix of the number of atoms present in it.
- The name of the anion should have a suffix '-ide' like for chlorine, the name will be chloride etc..
- For polyatomic ions, the suffix used will be '-ate' like for
the name will be sulfate etc..
Name of the given ionic compound is Gallium (III) Sulfate.
