Answer: Option (b) is the correct answer.
Explanation:
According to the law of conservation of mass, mass of a substance can neither be created nor it can be destroyed but it can simply be transformed from one form to another.
Therefore, when a metal is burned in a closed container, the mass of the container and its contents do not change because they follows law of conservation of mass.
Thus, we can conclude that when a metal is burned in a closed container, the mass of the container and its contents do not change then it is a law.
The compounds will yield Positive results for the permanganate, ninhydrin, and ceric ammonium nitrate tests are
permanganate test= ethene,
ninhydrin=aspasyic acid Phenylalanine
ceric ammonium nitrate test= methanol
<h3>What is a compound?</h3>
Generally, A compound is simply defined as a substance made up of two or more different chemical elements held together by chemical bonds that are difficult to break.
In conclusion, For the permanganate test= ethene,
ninhydrin=aspasyic acid Phenylalanine
ceric ammonium nitrate test= methanol

<span>Barometric pressure is just the same as
atmospheric pressure. It is called barometric pressure because the instrument
used to measure is called barometer. It is the pressure exerted by the air at a
certain altitude. Since it is the pressure exerted by the air, it is also known
as the weight of the air above the Earth. Depending on the altitude at which
the measurement is done, barometric or atmospheric pressure varies, but the
barometric pressure at sea level is 1 atm (atmosphere). It is equivalent to
101325 Pa (Pascal), 760 torr, 760 mm Hg and 1.01325 bar.</span>
