Asked by maham237 @ in Chemistry viewed by 496 People
Oil
Cornstarch
Sodium chloride
Sodium bicarbonate
Answered by maham237 @
Sodium chloride and Sodium bicarbonate are ionic substances
Further explanation
Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8
The formation of electron configurations such as noble gases can be done by sharing electrons with covalent bonds or hand over electrons with ionic bonds
Generally, ionic bonds occur in metals and nonmetallic elements.
While covalent bonds occur because of the use of shared electrons. In general, this bond occurs between nonmetallic elements, which has the same electron attraction
Characteristics of ionic compounds include: solid / crystalline form, soluble in water, conduct electricity
Let see the answer choices
Oil
It is a covalent compound because part of the hydrocarbon, a liquid that forms a bond between elements C, H and O, and does not dissolve in water (floats on water)
- Cornstarch
Obtained from corn which contains glucose which is a carbohydrate. It does not dissolve in water. Contains a bond between C, H and O. Includes covalent compounds
- Sodium chloride
- Sodium bicarbonate
Both are ionic compounds, soluble in water, in solid form
NaCl ⇒ Na⁺ + Cl⁻
NaHCO₃⇒ Na⁺ + HCO₃⁻
