We can say that when performing qualitative tests, one should take notes regarding the measurements of the substance or the observations being made regarding the morphology of cells.

<h3>What are qualitative tests?</h3>

This is a type of test that helps scientists measure is a substance is present or not, as well as morphological characteristics of cells in the case of the experiment being biological in nature. In these cases, we should write down any information regarding measurements of the substance we are searching for, or in the case of cells, any morphological characteristics that can be observed.

Therefore, we can confirm that when performing qualitative tests, one should take notes regarding the measurements of the substance or the observations being made regarding the morphology of cells.

Question 1-8
JulijaS [17]

If 28.0 grams of a gas occupies 22.4 liters at STP, the gas could be carbon monoxide, CO

<h3>Ideal gas </h3>

We understood from the ideal gas equation that 1 mole of any gas occupies 22.4 liters at standard temperature and pressure (STP)

<h3>How to determine the identity of the gas</h3>

To determine the identity of the gas, we shall determine the mass of 1 mole of each gas. This can be obtained as

For C₂H₂

1 mole of C₂H₂ = (12×2) + (2×1) = 26 g

For C₂H₆

1 mole of C₂H₆ = (12×2) + (6×1) = 30 g

For CO₂

1 mole of CO₂ = 12 + (16×2) = 44 g

For CO

I mole of CO = 12 + 16 = 28 g

From the above illustrations, we can see that 1 mole of CO is equivalent to 28 g.

Thus, the correct answer to the question is CO
