Answer:

The answer to this is

Unsaturated solution

Explanation:

An unsaturated solution has the property of having a solute concentration lower than the the solubility at equilibrium at a given temperature hence it has the capacity to dissolve more solutes. Is is a solution containing a lower amount of solute than a saturated solution

The two processes that occur on dissolving a solute in a solvent are dissolution and crystallization and in an unsaturated solution the rate of dissolution is greater than the rate of crystallization

Give the percent yield when 162.8 g of CO2 are formed from the reaction of excess amount of

Zepler [3.9K]

Answer:

84.86%

Explanation:

Step 1:

We'll begin by writing a balanced equation for the reaction between C8H18 and O2 to produce CO2. This is illustrated below:

2C8H18 + 25O2 —> 16CO2 + 18H2O

Step 2:

Now, let us calculate the mass of O2 that reacted and the mass of CO2 produced from the balanced equation above. This is illustrated below:

Molar Mass of O2 = 16x2 = 32g/mol

Mass of O2 from the balanced equation = 25 x 32 = 800g

Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol

Mass of CO2 from the balanced equation = 16 x 44 = 704g

Therefore the mass of O2 that reacted from the balanced equation is 800g

The mass of CO2 produced from the balanced equation is 704g

Step 3:

Determination of the theoretical yield of CO2. This is illustrated below:

From the balanced equation above,

800g of O2 reacted to produced 704g of CO2.

Therefore, 218g of O2 will react to produce = (218 x 704)/800 = 191.84g of CO2.

Therefore, the theoretical yield of CO2 is 191.84g

Step 4:

Determination of the percentage yield of CO2. This is illustrated below:

Actual yield = 162.8g

Theoretical yield = 191.84g

Percentage yield =?

Percentage yield = Actual yieldm/Theoretical yield x100

Percentage yield = 162.8/191.84 x100

Percentage yield = 84.86%

Therefore, the percentage yield of CO2 is 84.86%

Be sure to answer all parts. Write an unbalanced equation to represent each of the following reactions: Do not include phase abb

Eva8 [605]

Answer: The unbalanced chemical equations are written below.

Explanation:

An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.

For a:

The chemical equation for the reaction of nitrogen gas and oxygen gas follows:

$N_2+O_2\rightarrow NO_2$

The product formed is nitrogen dioxide.

For b:

The chemical equation for the decomposition of dinitrogen pentaoxide follows:

$N_2O_5\rightarrow N_2O_4+O_2$

The product formed is dinitrogen tetroxide and oxygen gas.

For c:

The chemical equation for the reaction of ozone to oxygen gas follows:

$O_3\rightarrow O_2$

The product formed is oxygen gas.

For d:

The chemical equation for the reaction of chlorine and sodium iodide follows:

$Cl_2+NaI\rightarrow NaCl+I_2$

The product formed is sodium chloride and iodine gas

For e:

The chemical equation for the reaction of magnesium and oxygen gas follows:

$Mg+O_2\rightarrow MgO$

The product formed is magnesium oxide

Answer:

Check the explanation

Explanation:

Acidipic Acid (which is an essential dicarboxylic acid for manufacturing purposes with about 2. 5 billion kilograms produced per year. It is mainly used for the production of nylon and its related materials.)

Going by the question, since the $H_{2} CrO_{4}$ is comparatively mild oxidizing agent than the $CrO_{3}$ , it only oxidizes the carbon group

How many seconds are there in 23 days ?

Brrunno [24]

Since there are 23 days and 24 hours in each day, you multi-ply them and get 552 hours. Since each hours is 60 minutes, 552*60 is 33120 minutes. Since one minute is 60 seconds, 60*33120 is 1,987,200 seconds. Therefore, there are 1,987,200 seconds in 23 days.
