The answer is dipole dipole interactions
Answer:
It is caused by currents of electricity that flow in the molten core.
<u>Answer:</u>
<u>For a):</u> The mass percent of naphthalene in the original sample is 31.00 %.
<u>For b):</u> The mass percent of 3-nitroaniline in the original sample is 32.03 %.
<u>For c):</u> The mass percent of benzoic acid in the original sample is 29.97 %.
<u>For d):</u> The total percent recovered is 93.00 %.
<u>Explanation:</u>
Percentage by mass is defined as the ratio of the mass of a substance to the mass of the solution multiplied by 100. The formula used for this is:
......(1)
a):
Mass of naphthalene = 0.483 g
Mass of the sample = 1.558 g
Plugging values in equation 1:

b):
Mass of 3-nitroaniline = 0.499 g
Mass of the sample = 1.558 g
Plugging values in equation 1:

c):
Mass of benzoic acid = 0.467 g
Mass of the sample = 1.558 g
Plugging values in equation 1:

d):
Total mass recovered = [0.483 + 0.499 + 0.467] = 1.449 g
Mass of the sample = 1.558 g
Plugging values in equation 1:

To get the least degree of precision I would model it after the kg amount or 4.05 or two decimal places so I would add 0.56795 or to two places would be 0.57 kg and then 0.1001 kg would be 0.1 kg so my answer would be 4.72 kg. In contrast, the greatest degree of precision would be 4050g + 567.95 grams plus 100.1 g= 4718.05 grams or 4.71805 kg. At least that is what I would think..
Answer:
True
