Answer:
q= 110.5 ke
Explanation:
Dipole moment is the product of the separation of the ends of a dipole and the magnitude of the charges.
μ = q * d
μ= Dipole moment (1.93 D)
q= partial charge on each pole
d= separation between the poles(109 pm).
e= electronic charge ( 1.60217662 × 10⁻¹⁹ coulombs)
So,
q= 
coulombs
q = 
e
q = 1.105 * 10⁵ e
q= 110.5 ke
If l = 2, then ml can be -2, -1, 0, 1, 2. There are 5 possible values.
Answer;
Molarity of NaOH is 0.80 M
Explanation;
The balanced equation for the reaction is;
2NaOH(aq) + H2SO4(aq = NaSO4(aq) +2 H2O (l)
Moles = concentration x volume
thus; 0.355M x 0.0282L= 0.01 moles of H2SO4.
Using the mole ratio;
Moles of NaOH = Moles of H2SO4 ×2
= 0.02 Moles
Therefore; moles of NaOH = 0.02 moles
But; Concentration = moles / volume
Thus; Concentration of NaOH = 0.02 / 0.025L
= 0.8M
Answer:
C. Reducing the air pressure allows the molecules to escape.
Explanation:
Lower air pressure can be found in the mountain or any high ground place. In this place, you will need less temperature to boil water or other liquid.
A liquid phase will change into gas when it reaches the vapor pressure of the surrounding air. At that point, the molecule can move freely as the gas phase. Since the atmospheric pressure is preventing the liquid to become gas, if the pressure is lower, the liquid can boil at a lower temperatures.
Because copper has a higher electrical and thermal conductivity than iron and is not susceptible to oxidation as easily.
