Type of intermolecular forces are expected between 3-bromopyridine molecules dipole induced dipole force.
Intermolecular pressure is the pressure among molecules it includes the forces of appeal and repulsion. however the intermolecular forces are weaker than intramolecular pressure, has London dispersion pressure.
Dipole precipitated Dipole Forces A dipole-brought on dipole enchantment is a weak enchantment that results while a polar molecule induces a dipole in an atom or in a non polar molecule by traumatic the arrangement of electrons inside the non polar species.
It is a dipole as the hydrogens have a partial superb fee and the oxygen has a partial negative charge. An precipitated dipole is the end result of molecules interacting and causing one of the molecules electrons to have this distorted rate.

<span>CO is the limiting reactant
( 25.0 x 3 = 75 moles of CO are required)
Moles Fe = 30.0 x 2 / 3 = 20.0
mass Fe = 20.0 x 55.847 g/mol=1117 g </span><span>

Answer: 9.98
Explanation:
1) The equation for the dissociation of pyridine is:
C₅H₅N₅(aq )+ H₂O(l) ⇄ C₅H₅NH⁺(aq) + OH⁻(aq)
2) Kb equation:
Kb = [C₅H₅NH⁺(aq)] [OH⁻(aq)] / [C₅H₅N₅(aq )]
Where:
[C₅H₅NH⁺(aq)] = [OH⁻(aq)] ← from the equilibrium reaction
[C₅H₅N₅(aq )] = 4.8 M ← from the statement
⇒ 1.9 × 10 ⁻⁹ = x² / 4.8 ⇒ x² = 9.12 × 10⁻⁹
⇒ x = 9.55 × 10⁻⁵ = [OH⁻(aq)]
3) pOH
pOH = - log [OH⁻(aq)] = 4.02
4) pOH + pH = 14
⇒ pH = 14 - 4.02 = 9.98
I would say the answer is A - a stars mass
The majority of stars in the galaxy, including our Sun, Sirius and Alpha Centauri A and B are all main sequence stars.
Mass is the key factor in determining the lifespan of a main sequence star, its size and its luminosity ( brightness)
Two characteristics define brightness: luminosity and magnitude. Luminosity is the amount of light that a star radiates. The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth.
Answer:
You will never know the exact volume with charles law
Explanation:
Doubling the temperature of gas doubles its volume, so long as the pressure and quantity of the gas are unchanged.
