Answer:

The correct option is;

b. It contains at least two colored substances

Explanation:

In chromatography, a mixture is separated into its components, such that in the filter paper, on which the drops of ethanol are then placed on the ink mark, we have different phases of the components of the mixture that have different levels of mobility by capillary action through the filter paper.   Therefore, given that two concentric rings of circles are obtained, we have that each ring is composed of a different component of the mixture and there are therefore, at least two colored substances.

Identify the balanced chemical equation that represents a single displacement reaction.
UNO [17]

3H₂SO₄ + 2Al₂(SO₄)₃  → Al₂(SO₄)₃ + 3H₂ is the balanced chemical equation that represents a single displacement reaction.

<h3>What is a balanced chemical equation?</h3>

The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.

3H₂SO₄ + 2Al₂(SO₄)₃  → Al₂(SO₄)₃ + 3H₂

In this type of reaction, one substance is replacing another:

A + BC  →  AC + B

In a single displacement reaction, atoms replace one another based on the activity series. Elements that are higher in the activity series. Also, if the element that is to replace the other in a compound is more reactive the reaction will occur. If it is less reactive, there will be no reation.

In the first equation, fluorine is more reactive than bromine. Therefore, bromine cannot replace bromine.

In the second equation, the displacement is between hydrogen and aluminium. Hydrogen is lower in the activity series, this implies that aluminium will replace it.

Hence, 3H₂SO₄ + 2Al₂(SO₄)₃  → Al₂(SO₄)₃ + 3H₂ is the balanced chemical equation that represents a single displacement reaction.
