Which of these could be separated by distillation or filtration
2 answers:
Answer: Option (B) is the correct answer.
Explanation:
A process where solute or solid particles which are present in a liquid or gas are separated out with the help of a filter medium like filter paper is known as filtration process.
For example, sand can be separated out from water by using a filter paper.
Components of a mixture can never combine chemically with each other.
Whereas, an element is a substance which contains only one type or kind of atoms.
For example, a pure zinc will contain only atoms of zinc.
A compound is defined as the substance in which different elements are chemically combined together in a fixed ratio by mass.
For example, is a compound and elements are present in 1:4 ratio.
A compound can be divided into its constituent or simpler substances.
Thus, we can conclude that a mixture could be separated by distillation or filtration.

Answer:
The pressure in mmHg is 1253 (option C)
Explanation:
Two quantities are directly proportional if when multiplying or dividing one of them by a number, the other is multiplied or divided by that number. In other words, the magnitudes are directly proportional when one magnitude increases and so does the other in the same proportion; or when one magnitude decreases and so does the other in the same proportion.
The rule of three or is a way of solving proportionality problems between three known values and an unknown value, which can be applied to directly proportional quantities as follows:
a ⇒ b
c ⇒ x
So
where a, b and c are data and x is the unknown value to be calculated.
In this case, knowing that 1 Torr = 1 mmHg, the rule of three can be applied as follows: if 1 torr is equal to 1 mmHg, 1253 torr is equal to how many mmHg?
pressure= 1253 mmHg
<u><em>The pressure in mmHg is 1253 (option C)</em></u>
