A gas sample has volume 3.00 dm3 at 101

vivado [14]

Answer:

21.3dm³

Explanation:

Given parameters:

Initial volume of gas = 3dm³

Initial pressure = 101kPa

Final pressure = 14.2kPa

Unknown

Final volume = ?

Solution:

To solve this problem, we use the Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

P₁ V₁ = P₂ V₂

P and V are pressure and Volume

1 and 2 are the initial and final states

Now insert the parameters and solve;

101 x 3 = 14.2 x V₂

V₂ = 21.3dm³

What is the reaction which a metal element displaces the metal atom of a compound?

Marina86 [1]

A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound. The starting materials are always pure elements, such as a pure zinc metal or hydrogen gas, plus an aqueous compound.

Why would a biological stain be used? (Give examples of stains and their uses)

Allushta [10]

Answer:

Biological stains are used for the medical and biological industries to aid in detection of structures within tissues. This can include the detection of abnormalities, but is not limited to that. The stains are used to define and examine cell populations within the tissues, to mark cells, or to flag proteins.
