60 points please help me i would appreciate it!

Explanation:

In the reaction:

for 1 mol of propane, 3 moles of CO₂ are produced.

Volume of propane = 13 L

At STP,

1 mol of propane = 22.4 L/dm³ molar value

So,

Moles in 13 L of propane:

= volume / molar volume

= 13 / 22.4

= 0.58 mol

Since,

1 mol of propane = 3 moles of CO₂

0.58 mol of propane = 3 × 0.58 mol of CO₂

0.58 mol of propane = 1.74 mol of CO₂

Converting 1.74 mol of CO₂ into L:

[Multiply it by 22.4 L/mol]

= 1.74 mol × 22.4 L/mol

= 39 L

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
