a.1
b. 2
c. 3
d. 4.

3

Explanation:

Chemical equation:

Fe + Cl₂  →  FeCl₃

Balanced chemical equation:

2Fe + 3Cl₂  →  2FeCl₃

when iron react with chlorine it form iron chloride. In given reaction oxidation reduction take place.

Iron becomes Fe⁺³ while chlorine Cl⁻¹ that's why three chlorine atoms react with one iron atom to make the compound overall neutral.

Coefficient with reactant and product.

Reactant              Product

Fe   =  2                 FeCl₃ = 2

Cl₂  =  3

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.  

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
