Answer:

Organelles; role.

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;

1. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.

2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.

3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.

4. Chromosomes : they give sets of instructions for the synthesis of products.

5. Ribosomes : they are involved in the build up of proteins.

6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.

7. Cytoskeleton : they help to maintain and support the shape of the cells.

8. Vesicles : they ensure proteins are properly transported to the right and exact location.

9. Golgi apparatus : it prepares the protein for export by chemically tagging them.

10. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.

Hence, cells are made of many parts, or organelles, that help the cell do its job. Each cell organelle has a specific function, or role.

How many grams of NH3 can be dissolved in 50 grams of water at 50oC?
weqwewe [10]

15 grams of  NH3 can be dissolved

<h3>Further explanation</h3>

Given

50 grams of water at 50°C

Required

mass of NH3

Solution

Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility  

  • 1. Temperature:
  • 2. Surface area:
  • 3. Solvent type:
  • 4. Stirring process:

We can use solubility chart (attached) to determine the solubility of NH3 at 50°C

From the graph, we can see that the solubility of NH3 in 100 g of water at 50 C is 30 g

So that the solubility in 50 grams of water is:

= 50/100 x 30

= 15 grams

The solubility product for an insoluble salt with the formula M2X3 is written as ________, where s is the molar solubility
masha68 [24]

Answer:

36s^5

Explanation:

We have;

M2X3 (s)------> 2M^3+(aq)  + 3X^2-(aq)

If [M^3+(aq)] = [X^2-(aq)] = s

We then have;

Ksp = (2s)^2 * (3s)^3

Ksp = 4s^2 * 9s^3

Ksp = 36s^5

Note that Ksp is known as the solubility product. It is an equilibrum equation that shows the solubility of a solute in water.

how many moles of sodium hydroxide (NaOH) are required to completely neutralize 2 mol of nitric acid (HNO3)
Brut [27]

2 moles of sodium hydroxide will be needed.

<h3><u>Explanation</u>:</h3>

Sodium hydroxide is a compound which is a base and nitric acid is the acid. The formula of the nitric acid is HNO3 and that of sodium hydroxide is NaOH.

The reaction between them are

NaOH +HNO3 =NaNO3 +H2O.

So here we can see that 1 mole of sodium hydroxide reacts with 1 mole of nitric acid to produce 1 mole of sodium nitrate and 1 mole of water.

So for 2 moles of nitric acid, 2 moles of sodium hydroxide will be required.
