The correct answer is false. It is not chemical equilibrium when the forward rate of reaction is greater than the reverse rate of reaction. Instead, these two rates should be equal to achieve chemical equilibrium.
Answer:
285.6 g
Explanation:
The elevation of the boiling point of a solvent that has a solute nonvolatile dissolved is called ebullioscopy, and the change in the temperature may be calculated by the Raoult's law:
ΔT = Kb.W.i
Where<em> ΔT</em> is the temperature change, <em>Kb</em> is the ebullioscopy constant, <em>W</em> is the molality and <em>i</em> is the Van't Hoff factor, which determinates the particles that affect the proper.
The molality is:
W = m1/(M1xm2)
Where <em>m1</em> is the solute mass (in g), <em>M1</em> is the molar mass of the solute, and <em>m2</em> is the mass of the solvent (in kg). Sodium chloride has molar mass equal to 58.5 g/mol (23 of Na and 35.5 of Cl), so:
(100 - 95) = 0.512xWx2
5 = 1.024W
W = 4.883 m
W = m1/(M1xm2)
4.883 = m1/(58.5x1)
m1 = 285.6 g
I would say B) hawk and coyote.
Hope this helps!
