Melting point is dependent on the intermolecular forces which means the bonds between the molecules of bromine as it is a simple molecular structure the intermolecular bonds of bromine are weak bcz they are weak vandervaal forces thats why Bromines melting point is low..In short when intermolecular bomds are weak the M.P is lower
Answer:
c it has the qualities of all the above
Answer:
D) all of the above
Explanation:
<em>Which of the following represents 1 mol of phosphine gas, PH₃? </em>
<em>A) 6.02 x 10²³ phosphine molecules.</em> YES. Considering Avogadro's number, 1 mole of a substance contains 6.02 x 10²³ molecules of such substance.
<em>B) 34.00 g phosphine gas.</em> YES. The molar mass of phosphine is equal to the sum of the molar masses of the elements that form it.
MM(PH₃) = MM(P) + 3 × MM(H) = 31.00 g/mol + 3 × 1.00 g/mol = 34.00 g/mol.
<em>C) 22.4 L phosphine gas at STP.</em> YES. At standard temperature (0 °C) and pressure (1 atm), 1 mole of any gas occupies a volume of 22.4 L.

Hope this answer can help you. Have a nice day!
Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading
