Answer:

KO₂ and O₂ have 4:3 molar rato

Explanation:

Reaction Given

4KO₂+2CO₂→2K₂CO₃+3O₂

chemicals have a molar ratio of 4:3 = ?

Solution

First look at the Reaction

4KO₂ + 2CO₂-------→ 2K₂CO₃ + 3O₂

write the moles of the reactant and products that involve

4KO₂ + 2CO₂ -------→ 2K₂CO₃ + 3O₂

4 mol 2 mol 2 mol 3 mol

So the coefficients shows the number of moles of that compound involve in the reaction,

if we look for each ratio of moles to other

4 moles of KO₂ : 2 moles of CO₂

So the molar ratio of KO₂ to CO₂ is 4: 2

4 moles of KO₂ : 2 moles of K₂CO₃

So the molar ratio of KO₂ to K₂CO₃ is 4 : 2

2 moles of CO₂ : 2 moles of K₂CO₃

So the molar ratio of CO₂ to K₂CO₃ is 4 : 2

4 moles of KO₂ : 3 moles of O₂

So the molar ratio of KO₂ to O₂ is 4: 3

It is clear that KO₂ and O₂ are the chemicals in this reaction that are in the 4:3 molar ratio

Percentage of an aldrin in the sample is 44.41%.

Explanation:

$Cl^-+AgNO_3\rightarrow AgCl+NO_{3}^-$

Molarity of the silver nitrate solution = 0.03337 M

Volume of the silver nitrate = 23.28 mL = 0.02328 L

Moles of silver nitrate = n

$0.03337 M=\frac{n}{0.02328 L}$

n = $0.03337 M\times 0.02328 L=0.0007768 mol$

According to reaction 1 mole of silver nitrate recats with 1 moles of chloride ions.

Then 0.0007768 moles of silver nitrate will react with:

$\frac{1}{1}\times 0.0007768 mol=0.0007768 mol$ chloride ions.

In one mole of aldrin there are 6 moles of chloride ions.

Then moles of aldrin containing 0.0007768 moles chloride ions are:

$\frac{0.0007768 mol}{6}=0.0001295 mol$

Moles of aldrin present in the sample = 0.0001295 mol

Mass of 0.0001295 moles of aldrin present in the sample :

0.0001295 mol × 364.92 g/mol =0.04726 g

Percentage of an aldrin in the sample:

$\frac{0.04726 g}{0.1064 g}\times 100=44.41\%$

When C2H5Cl(g) is burned in oxygen, chlorine gas is produced in addition to carbon dioxide and water vapor. 5145 kJ of heat are

Arisa [49]

<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

$\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O$

The chemical equation for the combustion of ethyl chloride follows:

$4C_2H_5Cl+13O_2\rightarrow 2Cl_2+8CO_2+10H_2O$

We are given:

When 4 moles of ethyl chloride is burnt, 5145 kJ of heat is released.

For an endothermic reaction, heat is getting absorbed during a chemical reaction and is written on the reactant side.

$A+\text{heat}\rightleftharpoons B$

For an exothermic reaction, heat is getting released during a chemical reaction and is written on the product side

$A\rightleftharpoons B+\text{heat}$

So, the chemical equation follows:

$4C_2H_5Cl+13O_2\rightarrow 2Cl_2+8CO_2+10H_2O+5145kJ$

Hence, the chemical equation is written above.

On the graph, which shows the potential energy curve of two N atoms, carefully sketch a curve that corresponds to the potential

ki77a [65]

Answer:

Explanation:

We are to carefully sketch a curve that relates to the potential energy of two O atoms versus the distance between their nuclei.

From the diagram, O2 have higher potential energy than the N2 molecule. Because on the periodic table, the atomic size increases from left to right on across the period, thus O2 posses a larger atomic size than N2 atom.

Therefore, the bond length formation between the two O atoms will be larger compared to that of the two N atoms.

USPshnik [31]

The graph is not given in the question, so, the required graph is attached below:

Answer:

According to the graph, the relationship between the density of the sugar solution and the concentration of the sugar solution is directly proportional to each other as they both are increasing exponentially.

The graph shows that, the density of sugar solution will increase with the increase in concentration of sugar in the solution.
