<span>Answer is </span>(3)
- Sodium Nitrate.<span>
</span>Normally ionic bonds can be seen between
metals and non-metals while covalent
bonds present between
non-metals. Another thing that determines the bond nature is electronegativity
value of the atoms.
If the electronegativity difference
is high, then that bond tends to be an ionic bond.<span>
</span><span>Sodium nitrate consists of </span>Na⁺<span> and </span>NO₃⁻ ions. Hence, the bond
between Na⁺ and NO₃⁻<span> is an </span>ionic
bond. <span><span>
NO</span>₃⁻ </span><span>is made from </span>N <span>and </span>O<span>. Both are </span>non-metallic
atoms. <span>The </span>electronegativities <span>of </span>N <span>and </span>O <span>are </span>3.0 <span>and </span>3.5 <span>respectively. Hence, there is </span>no
big difference between
electronegativity values (3.5 - 3.0 = 0.5<span>). Hence, the bond
between N and O is a </span><span>covalent
bond. </span>

Answer:
1033.36g
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This means that 1 mole of SO2 also contains 6.02x10^23 molecules.
1 mole SO2 = 32 + (16x2) = 64g.
Now, If 64g of SO2 contains 6.02x10^23 molecules,
Therefore, Xg of SO2 will contain 9.72x10^24 i.e
Xg of SO2 = (64x9.72x10^24)/6.02x10^23
Xg of SO3 = 1033.36g.
Therefore, 1033.36g of SO2 contains 9.72x10^24 molecules
