Determine the mass of CuSO4 • 5H20 that must be used to prepare 250mL of 2.01 M CuSO4(aq).

Answer in units of g.

Answers

Answer 1

Given parameters:

Volume of CuSO₄ = 250mL

Concentration of CuSO₄ = 2.01M

Unknown:

Mass of CuSO₄.5H₂O = ?

To solve this problem, we must write the chemical relationship between both species.;

             CuSO₄.5H₂O  →   CuSO₄ + 5H₂O

Now that we know the expression, it is possible to solve for the unknown mass.

First find the number of moles of CuSO₄;

         Number of moles  = Concentration x Volume

Take 250mL to L so as to ensure uniformity of units;

           Volume  = 250 x 10⁻³L

  Input the parameters and solve for number of moles;

        Number of moles  = 250 x 10⁻³  x  2.01 = 0.5mol

From the equation;

             1 mole of CuSO₄ is produced from 1 mole of CuSO₄.5H₂O  

So  0.5 moles of CuSO₄ will be produced from 0.5 moles of CuSO₄.5H₂O

Now let us find the molar mass of CuSO₄.5H₂O = 63.6 + 32 + 4(16) + 5(2x1 + 16)  = 249.6g/mole

Mass of CuSO₄.5H₂O = number of moles x molar mass

                                      = 0.5 x 249.6

                                     = 124.8g

The mass of CuSO₄.5H₂O is 124.8g

Two common materials we encounter in our daily lives are radiator coolant in automobiles and dry ice. The coolant in an automobile radiator, a solution of antifreeze (a glycol such as ethylene or propylene glycol) and water, freezes at 39°C and boils at 110°C. The temperature of the dry ice (solid carbon dioxide) used in some ice cream vending carts is –78°C. Convert the boiling point of radiator coolant (110°C) to degrees Fahrenheit. Convert the temperature of dry ice (–78°C) to the Kelvin scale.

Answers

Answer:

See explanation

Explanation:

Using the formula

°C = (F-32) × 5/9

Where;

°C = temperature in degrees centigrade

F= temperature in Fahrenheit

F= (9/5 ×°C) +32

F= (9/5 × 110) + 32

F= 230°F

To convert -78°C to Kelvin

-78°C + 273 = 195 K

Propose a structure for an aromatic hydrocarbon, C9H12, that can form two C9H11Cl products on substitution of a hydrogen on the aromatic ring with chlorine. You do not have to consider stereochemistry. In cases where there is more than one answer, just give one. Ignore the ortho, para-directing effects of the alkyl groups in answering this question. Consider only the number of nonequivalent hydrogens on the aromatic ring.

Answers

Answer:

Explanation:

From the given study,

the molecular formula of the given aromatic compound = C9H12

the first process we suppose to carry out is to calculate the double bond equivalence.

So, the double bond equivalence [tex]DBE = {N_C+1-(\dfrac{(N_H+N_{Cl})-N_H}{2}) }[/tex]

[tex]DBE = {9+1-(\dfrac{(12+0)-0}{2}) }[/tex]

DBE = 4

Hence, the aromatic compound possesses 4 double bonds, this signifies that the might be a presence of benzene ring.

The substitutional products of the aromatic hydrocarbon C9H12 can be seen in the attached file below.

Answers

Answer:

Put the light bulb that was removed back into the circuit and observe whether the other lights come on.

Explanation:

If all three bulbs initially glowed and she supposes that after removing the first bulb, the others stopped glowing because they burned out, then she must replace the original bulb and see if the other two bulbs will glow.

If all three bulbs don't glow after replacing the first one, then all the bulbs may have probably burned out.

How many moles of H2 can be formed if a 4.71 g sample of Mg reacts with excess HCl?

Answers

Answer:

0.2 mole of H2.

Explanation:

We'll begin by calculating the number of mole in 4.71 g of magnesium (Mg). This can be obtained as follow:

Mass of Mg = 4.71 g

Molar mass of Mg = 24 g/mol

Mole of Mg =?

Mole = mass /Molar mass

Mole of Mg = 4.71 /24

Mole of Mg = 0.2 mole

Next, we shall write the balanced equation for the reaction.

This is illustrated below:

Mg + 2HCl —> MgCl2 + H2

From the balanced equation above,

1 mole of Mg reacted to produce 1 mole of H2.

Finally, we shall determine the number of mole of H2 produced from the reaction. This can be obtained as illustrated below:

From the balanced equation above,

1 mole of Mg reacted to produce 1 mole of H2.

Therefore, 0.2 mole of Mg will also react to produce 0.2 mole of H2.

Thus, 0.2 mole of H2 was obtained from the reaction.

The number of moles of H₂ that can be formed if a 4.71 g sample of Mg reacts with excess HCl is 0.19625 moles

Let's represent the reaction with a chemical equation

Mg + HCl → MgCl₂ + H₂

Mg + 2HCl → MgCl₂ + H₂

HCl is in excess according to the question. This means Mg is the limiting reagent and therefore determine the amount of product.

Therefore,

24 g of Mg gives 2g of  H₂

4.71 g of Mg will give ? H₂

cross multiply

mass of H₂ = 4.71 × 2 / 24

mass of H₂ = 9.42 / 24 = 0.3925 g

moles of H₂ = mass / molar mass

moles of H₂ = 0.3925 / 2

moles of H₂ = 0.19625 moles

The vapor from elemental mercury metal is a neurotoxin. Most dentists have levels of mercury in their urine of 10 micrograms per liter (1 microgram is 10^-6 grams), which is about twice that

of their patients. The legal safe maximum exposure limit for mercury in urine is 4.053 x 10^17 atoms of mercury per liter of urine. Does this level mean that the average dentist is at risk for

mercury poisoning? In other words, is this amount, 10 micrograms per liter of urine, above or below the legal safe limit? Show your work and justify your answer.

Answers

Answer: 10 micrograms per liter of urine is below the legal safe limit and the dentist is not at risk for mercury poisoning.

Explanation:

To calculate the number of moles, we use the formula:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]

We are given:

Given mass of mercury = [tex]10\mu g=10^{-5}g[/tex]        (Conversion factor: [tex]1\mu g=10^{-6}g[/tex] )

Molar mass of mercury = 200.6 g/mol

Putting values in above equation, we get:

[tex]\text{Moles of mercury}=\frac{10^{-5}g}{200.6g/mol}\\\\\text{Moles of mercury}=4.9\times 10^{-8}mol[/tex]

According to mole concept:

1 mole of an element contains [tex]6.022\times 10^{23}[/tex] number of atoms

So, [tex]4.9\times 10^{-8}[/tex] moles of mercury will contain = [tex]\frac{6.022\times 10^{23}}{1}\times 4.9\times 10^{-8}=2.95\times 10^{16}[/tex] number of atoms.

We are given:

Legal safe limit for mercury in urine = [tex]4.053\times 10^{17}[/tex] atoms

Calculated amount of mercury in urine = [tex]2.95\times 10^{16}[/tex] atoms

As, the calculated amount of mercury in urine is less than the legal safe limit of mercury in urine. So, the average dentist is not at risk for mercury poisoning.

Hence, 10 micrograms per liter of urine is below the legal safe limit and the dentist is not at risk for mercury poisoning.

Sodium, like all the elements on that column have one valence electron. Valence electrons are the electrons found at the most outer shell of an atom. These are the electrons that do all the chemistry stuff. Oxygen on the other hand has six valence electrons. Adding just one sodium atom to an oxygen atom won’t create a stable bond( eight valence electrons). Sodium needs to lose one electron while oxygen needs to gain two. Therefore, by adding two sodiums( each transfers one electron to oxygen) to one oxygen, you get a stable bond and Sodium Oxide. I hope that this helps.

Explanation:

In the anaerobic fermentation of grain, the yeast Saccharomyces cerevisiae digests glucose from plants to form the products ethanol and propenoic acid by the following reactions: Reaction 1: C6H12O6  2 C2H5OH + 2 CO2 Reaction 2: C6H12O6  2 C2H3CO2H + 2 H2O In an open flow reactor 4000 kg of a 12% glucose-water solution flows in. During fermentation, 120 kg of carbon dioxide is produced together with 90 kg of unreacted glucose. What are the weight percents of ethyl alcohol and propenoic acid that exit the broth? Assume that none of the glucose is assimilated into the bacteria.

Answers

Answer:

Explanation:

The first step in order to solve this particular question is to make sure that the two reactions given in the question is balanced. Therefore, we have;

Reaction 1: C6H12O6 -----------------------------> 2 C2H5OH + 2 CO2.

Reaction 2: C6H12O6 ------------------------------> 2 C2H3CO2H + 2 H2O.

Next, we determine the number of moles of water and that of glucose. Recall that we are given from the question that the open flow reactor =  4000 kg of a 12% glucose-water solution flows in that is to say the percentage for water is [100% - 12% = 88%]. Also, the molar mass of water = H₂O = 18 kg/kmol and that for glucose =180 kg/kmol.

Number of moles of water = (4000 kg × 88%) ÷ 18 = 195.6 kmol.

Number of moles of glucose= (4000kg × 12%) ÷ 180 = 2.67 kmol.

Next thing to do is to determine the number of moles in the unreacted glucose . Therefore, the 90 kg of unreacted glucose ÷ 180kg/kmol = 0.5  kmol.

So, we have that During fermentation, 120 kg of carbon dioxide is produced.  Thus, the number of kmol = 120kg÷ 44kg/mol = 2.73kmol.

For reaction 1, we have 2 moles of CO₂ that is to say the extent of the reaction = 2.73kmol / 2 moles of CO₂ = 1.365 kmol.

For reaction 2, we have 2 moles of CO₂ that is to say the extent of the reaction = 2.67kmol - 0.5  kmol - 1.365kmol = 0.805 kmol.

For both reaction, the kmol for outflow of glucose = 2.73 kmol.

Also, 2 × 0.805 + 1.365 × 0 = 1.61kmol.

Hence, 195.6 kmol + 1.61 =197.21 kmol.

The mass of ethanol = 46.1 kg/kmol × 2.73 kmol = 125.853 kg.

The weight percent of ethanol has been 29.72%, and the percent mass of propionic acid has been 47.79%.

The balanced chemical equations of the reactions have been:

[tex]\rm C_6H_1_2O_6\;\rightarrow\;2\;C_2H_5OH\;+\;2\;CO_2[/tex]

[tex]\rm C_6H_1_2O_6\;\rightarrow\;2\;C_2H_3CO_2H\;+\;2\;H_2O[/tex]

The solution has consisted of 12% glucose.

Water in the solution = 88%

The mass of the solution = 4000 kg.

The moles of glucose = 12% of 4000 kg

Moles of glucose = [tex]\rm \dfrac{12}{100}\;\times\;4000\;\times\;\dfrac{1}{180\;g/mol}[/tex]

Moles of glucose = 2.67 kmol.

Moles of water =  88 % of 4000 kg

Moles of water = [tex]\rm \dfrac{88}{100}\;\times\;4000\;\times\;\dfrac{1}{18\;g/mol}[/tex]

Moles of water = 195.6 kmol.

The unreacted glucose in the mixture = 90 kg

Moles of unreacted glucose:

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

Moles of unreacted glucose = [tex]\rm \dfrac{90\;\times\;1000\;g}{180\;g/mol}[/tex]

Moles of unreacted glucose = 0.5 kmol

The mass of carbon dioxide produced = 120 kg.

Moles of carbon dioxide produced = [tex]\rm \dfrac{120\;\times\;1000\;g}{44\;g/mol}[/tex]

Moles of carbon dioxide produced = 2.73 kmol

Since 1 mole of glucose produces 2 moles of carbon dioxide.

2.73 kmol of carbon dioxide has been produced from 1.365 kmol of glucose.

The moles of ethanol produced by reaction 1 = 2 moles/ mole glucose.

The glucose present has been 2.67 kmol.

The ethanol produced = 5.34 kmol.

Moles of propionic acid produced = 5.34 kmol.

The mass of 5.34 kmol ethanol = Moles × molecular weight

The mass of ethanol produced = 5.34 × 1000 × 46.07g/mol

The mass of ethanol produced = 246.0138 kg.

The mass of propionic acid produced = 5.34  × 1000 × 74.08 g/mol

The mass of propionic acid produced = 395.5872 kg.

The mass of water produced = 5.34 × 1000 × 18 g/mol

The mass of water produced = 96.12 kg.

The remained glucose = 90 kg

The total mass in the reactor:

= Mass of glucose + water + propionic acid + ethanol

= 90 + 96.12 + 395.5872 + 246.0138 kg

= 827.721 kg.

% Mass of ethanol = [tex]\rm \dfrac{Mass\;of\;ethanol}{Total\;mass}\;\times\;100[/tex]
