opposite
Explanation:
Ionic compounds connects and holds together due to the opposite ionic charges that each element in the compound forms.
Ionic bonds are formed as a result of the electrostatic attraction between oppositely charged ions.
This force is a force of attraction that pulls ions to form compounds.
- Ionic bonds are formed between two species with a large electronegativity difference.
- This is usually a metal and a non-metal in nature.
- The metal loses its electron and becomes positively charged.
- The non-metal due to its electronegativity gains the electrons and becomes negatively charged.
- Attraction between these oppositely charged specie leads to the formation of ionic bonds.

Correct Answer: Option D i.e. 34.8 gReason:
Molecular weight of HgS = 232.66 g/mol
Atomic weight of Hg = 200.59 g/mol
Thus, 200.59 g Hg ≡ 232.66 g of HgS
Therefore, 30 g of Hg ≡
![\frac{232.66X30}{200.59}](https://tex.z-dn.net/?f=%20%5Cfrac%7B232.66X30%7D%7B200.59%7D%20)
= 34.8 g
Thus,
34.8 g HgS would contain 30 g mass percent of Hg
Answer:
2 Cu2O + C → 4 Cu + CO2
This is an oxidation-reduction (redox) reaction:
4 CuI + 4 e- → 4 Cu0 (reduction)
C0 - 4 e- → CIV (oxidation)
Cu2O is an oxidizing agent, C is a reducing agent.

Answer:
Percentage Yield is calculated by doing -> experimental/theoretical x 100% = percentage yield.
I THINK that if your questions are connected it should be 14/16.89 x 100% = 82.889%
