Inefficiency of the material or engine causes the output work of a machine to be less
than the input work. It is governed by the second law of thermodynamics wherein
no product of work can produce 100 percent efficiency. Only the Carnot engine
can produce a 100 percent effieciency.
The mass of the sample reported is 3.5465 g option e is correct.
Mass is the quantitative measure of the physical body.
The mass of the empty sample container is given as 12 g.
The mass of empty as well as sample containers is given as 15.5465 g.
Therefore, the mass of the sample will be given as :
Mass of sample = mass of a sample as well as empty containers - a mass of empty sample container
= 15.5465 - 12
= 3.5465 g
Therefore, the mass of the sample reported is 3.5465 g option e is correct.

Complete question:
Your question is incomplete, but most probably your full question was, A label on an empty sample container reads 12.00 g. you add in a sample of a compound and the mass of the sample container obtaining 15.5465 g. what should the mass of the sample be reported as?
a) 3.546 g
b) 3.54 g
c) 4 g
d) 4.0 g
e) 3.5465 g
For this question, I think it is the other way around. It is true that chloroacetic acid is stronger in strength than acetic acid. Acid strength is measured as the equilibrium constant of the reaction <span>HA -----> H+ + A-
</span><span> In acetic acid, the anion produced by dissociation is CH3-COO-; in chloroacetic acid it is CH2Cl-COO-. Comparing the two, in the first one the negative charge is taken up mostly by the two oxygen atoms. In the second there is also an electronegative chlorine atom nearby to draw more charge towards itself. Therefore, the charge is less concentrated in the chloroacetate ion than it is in the acetate ion, and, accordingly, chloroacetic acid is stronger than acetic acid. </span>
Answer:
Aluminium is malleable. It means it can be hammered or changed into other shapes easily. In this case, the shape of a soft drink can.
Explanation:
This is my answer.
<span>A pure substance contains only one kind of molecule, and a mixture is a combination of two or more pure substances.</span>
