Explanation:
The given data is as follows.
Solvent 1 = benzene, Solvent 2 = water
= 2.7, = 100 mL
= 10 mL, weight of compound = 1 g
Extract = 3
Therefore, calculate the fraction remaining as follows.
=
=
=
Hence, weight of compound to be extracted = weight of compound - fraction remaining
= 1 -
= 0.00001
or, =
Thus, we can conclude that weight of compound that could be extracted is .
Answer:
A is the answer. Hope this helped.
Answer:
I think C
Explanation:
because hydrogen on the right side only have two while on the left side it have 4
To answer this question, you need to know <span>Graham's Law of Effusion/Diffusion formula. In this formula, the rate of diffusion/effusion would be influenced by the mass. As the molecule has bigger mass, the rate should be slower because it will be harder to pass the membrane. The calculation should be:</span>
<span>Rate 1 / Rate 2 = √[M2/M1]
</span>4.11/1= √[M2/2]
M2=33.78 g/mol
Answer:
Covalent, or, elements on the right side of the ladder (on the periodic table). Covalent compounds satisfy the octet rule by sharing electrons.
