Ksenya-84 [330]3 years ago
5 0

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.

Sodium chloride can be produced from reacting sodium metal with chlorine gas. Carly reacts 2.6 g of sodium with 5.0 g of chlorin
Artemon [7]

Answer:

87.75%

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2Na + Cl₂ —> 2NaCl

Next, we shall determine the masses of Na and Cl₂ that reacted and the mass of NaCl produced from the balanced equation. This can be obtained as follow:

Molar mass of Na = 23 g/mol

Mass of Na from the balanced equation = 2 × 23 = 46 g

Molar mass of Cl₂ = 2 × 35. 5 = 71 g/mol

Mass of Cl₂ from the balanced equation = 1 × 71 = 71 g

Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol

Mass of NaCl from the balanced equation = 2 × 58.5 = 117 g

Summary:

From the balanced equation above,

46 g of Na reacted with 71 g of Cl₂ to produce 117 g of NaCl.

Next, we shall determine the limiting reactant.

This can be obtained as follow:

From the balanced equation above,

46 g of Na reacted with 71 g of Cl₂.

Therefore, 2.6 g of Na will react with = (2.6 × 71)/46 = 4.01 g of Cl₂.

From the calculations made above, we can see that only 4.01 g of Cl₂ at of 5 g given in question reacted completely with 2.6 g of Na. Therefore, Na is the limiting reactant and Cl₂ is the excess reactant.

Next, we shall determine the theoretical yield of NaCl. The limiting reactant will be used to obtain the theoretical yield since all of it is consumed in the reaction.

The limiting reactant is Na and the theoretical yield of NaCl can be obtained as follow:

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

Therefore, 2.6 g of Na will react to produce = (2.6 × 117)/46 = 6.61 g of NaCl.

Thus the theoretical yield of NaCl is 6.61 g

Finally, we shall determine the percentage yield of NaCl. This can be obtained as follow:

Actual yield of NaCl = 5.8 g

Theoretical yield of NaCl = 6.61 g

Percentage yield =?

Percentage yield = Actual yield /Theoretical yield × 100

Percentage yield = 5.8/6.61 ×100

Percentage yield of NaCl = 87.75%

Why is Mars visible from earth in the night sky
Studentka2010 [4]
<span>You can see mars in the night sky because it is a very bright planet. Mars is as bright, or brighter than the stars. Yes, all planets are pretty bright, but mars in beyond bright along with jupiter, mercury, etc. Hope this helped! :)</span>
