Answer:

The cell theory claims these three components:

1. cell is the smallest functional unit of life: It can be observed under the microscope that cells have various type of molecules and organelles present and have adifferent functional role in the cell which explains that the cell is the smallest unit of life as its molecules or organelles can not carry the life process on their own.

2. All organisms are made up of cells: From bacteria and archaea to human and other life forms are made up of a single cell or organization of cells in a specific pattern it also can be observed by the microscopic of blood or other tissue or cell of an organism.

3. Arise from pre-existing cell: The cells are can be studied under a microscope during cell division where we can observe that new cells come from the pre existing cell by the cell division.

Arrange the compounds in order from highest to lowest boiling point. Consider how noncovalent interactions would affect the boil
malfutka [58]

Answer:

Isopropanol>dichloromethane>1-butene>propane

Explanation:

Stronger intermolecular forces usually correlate with higher boiling points

Boiling points generally increases with molecular weight due to increased strength of dispersion forces

Hydrocarbons exhibit only dispersion forces.

For the arrangement of compounds above, isopropanol has the highest boiling point because it forms hydrogen bonds with water. Dichloromethane possess dipole-dipole interaction which accounts for its higher boiling point. 1-butene has a higher boiling point than propane because it has higher molecular mass thus greater dispersion forces.

1.72 mol of LiCl in 37.5 L of solution
givi [52]
<h3>Answer:</h3>

Molarity is 0.046 M

<h3>Explanation:</h3>

We are given;

1.72 mol of LiCl in 37.5 L of solution

We will take the question to be; calculate the molarity of LiCl

Therefore,

we can start by defining molarity as the concentration of a solution in moles per liter.

Molarity of a solution is calculated by dividing the number of moles of solute by the volume of solution.

Molarity = Moles of solute ÷ Volume of the solution

Thus, in this case;

Molarity of LiCl = Moles of LiCl ÷ Volume of the solution

                          = 1.72 moles ÷ 37.5 L

                          = 0.0459 M

                         = 0.046 M

Therefore, the molarity of LiCl solution is 0.046 M
