The formula weight of CuCl is: 98.999
<span>Percent compositions are usually weight percent (abbreviated w/o). </span>
<span>Since CuCl has one mole of each element, the calculation is simple. </span>
<span>For Cu it is: (63.546 / 98.999) x 100% = 64.189 w/o </span>
<span>For Cl it is 100.000 - 64.189 = 35.811 w/o </span>
Explanation:
An ionic solution is a solution that has anions and cations. This is formed when ionic compounds dissociate in water. The ionic solution can be used as a battery because their respective ions can be attracted to either node of a battery. The cathode (+) attracts anions (negatively charged ions) and the anode (-) attracted cations (positively-charged ions). The reaction between the nodes and the respective ions in the solution causes electrons do be either donated or received. This ensures that the ionic solution (electrolyte) acts as channels for transport of electrons across the nodes to complete a circuit.

Some patterns and trend that are present in the periodic table would be
1. electronegativity (from left-to-right it increases across the table)
2. ionization (from left-to right it increases and from bottom-to-top it increases)
3. electron affinity (same as ionization energy)
4. atom radius (increases opposite way; from right-to-left it increases and from top-to-bottom it increases)
5. melting point (higher melting points with metals and lower melting point with non-metals)
6. metallic character (same as atom radius)
Answer:
Explanation:
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards itself and becomes partial negative while the other atom becomes partial positive.
Non polar covalent bond:
It is the bond where both bonded atoms share the pair of electron equally.
For example:
Hydrogen gas (H₂) is non polar covalent compound because the electronegativity of both bonded atoms are same. No poles are created that's why this is non polar covalent compound.
Polar covalent bond:
It is the bond where both bonded atoms share the pair of electron unequally.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive and bond is polar.
