<h3>What is a polar covalent bonds?</h3>
A bond is polar covalent when the electronegativity difference between the bonding atoms is above that found in a nonpolar covalent bond. Now we shall see the types of bonds between these atoms.
- Si and O - polar covalent
- O and O - Covalent
- C and H - Covalent
- Li and F - ionic
- Ba and S - ionic

Answer:
2 pair of an electron
Explanation:
carbon having 6 valence electron 2 electron involved in covalent bonding so 4 electron means 2 pairs of an electron will left.
Answer:
The process of forming the iron - rich core, the low density crust which is also rich in silicon, oxygen, aluminum, and the intermediate density mantle rich in silicon, oxygen, and magnesium is called the differentiation. Thus, the answer to this item is letter A.
Explanation:
Sodium carbonate is used to neutralised sulfuric acid, H₂SO₄. Sodium carbonate is the salt of stron base (NaOH) and weak acid (H₂CO₃). The balanced chemical reaction for neutralization is as follows:
Na₂CO₃ + H₂SO₄→ Na₂SO₄ + H₂CO₃
From balanced chemical equation, it is clear that one mole of Na₂CO₃ is required to neutralize one mole of H₂SO₄. Molar mass of Na₂CO₃= 106 g/mol=0.106 kg/mol and molar mass of H₂SO₄= 98 g/mol=0.098 kg/mol.
To neutralize 0.098 kg of H₂SO₄ amount of Na₂CO₃ required is 0.106 kg, so, to neutralize 5.04×10³ kg of H₂SO₄, Na₂CO₃ required is= kg= 5.451 X 10³ kg.
