A container of gas occupies 3.5 L at 585 mmHg. What would the new pressure be if the volume decreases to 2.0L?

1023.75mmHg

Explanation:

V1 = 3.5L

P1 = 585mmHg

V2 = 2.0L

P2 = ?

To solve this question, we'll require the use of Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature is kept constant.

Mathematically,

V = kP, k = PV

P1 × V1 = P2 × V2 = P3 × V3 = = Pn × Vn

P1 × V1 = P2 × V2

Solve for P2,

P2 = (P1 × V1) / V2

P2 = (585 × 3.5) / 2.0

P2 = 2047.5 / 2.0

P2 = 1023.75mmHg

The final pressure of the gas is 1023.75mmHg

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.
