A) You begin preparation of the calibration curve to measure absorbance vs concentration of FeSCN2+. To do so, you add 4.128 mL of 0.150 M Fe(NO3)3 to a cuvette and then directly add 210.454 µL of 0.001 M KSCN. What is the resulting concentration of FeSCN2+, assuming complete conversion of SCN- to FeSCN2+? Provide your response to four digits after the decimal; be careful with your exponent, it must complete this expression: __________ x 10-3 M.
B) If the initial amount of Fe(NO3)3 transferred to the cuvette is 0.046 mol, and the absorbance measurements indicate that 0.024 mol of FeSCN2+ are present at equilibrium, what must be [Fe3+] at equilibrium? The total volume of solution in the cuvette is 2.451 mL. Provide your response to two digits after the decimal.

What is volume?The volume of a substance is a measurement of how much space it occupies. Matter is a term used to describe a physical substance that has mass and occupies space.Cubic metres are the accepted unit of volume in physical sciences like chemistry (m3). From this, other units like the litre (L) and millilitre (mL) are generated (mL). The area occupied within an object's three-dimensional bounds is referred to as its volume. The object's capacity is another name for it.Volume is the amount of space that an object takes up, whereas capacity is the characteristic of a container, especially how much liquid it can hold.

Therefore,

Moles of ferric nitrate [tex]$=0.026 \mathrm{~mol}$[/tex]

Concentration of ferric nitrate [tex]=\frac{0.026 \mathrm{~mol}}{2.164 \times 10^{-3} \mathrm{~L}}=12.015 \mathrm{M}$[/tex]

12.015M of ferric nitrate solution will contain: If 1 mole of ferric nitrate yields 1 mole of ferric ions, then

Moles of [tex]$F e(S C N)]^{2+}$[/tex] at equilibrium  = 0.01 mol

Concentration of [tex]$F e(S C N)]^{2+}$[/tex] at equilibrium =

[tex]$[\mathrm{Fe}(S C N)]^{2+}=\frac{0.01 \mathrm{~mol}}{2.164 \times 10^{-3} \mathrm{~L}}=4.621 \mathrm{M}$[/tex]

[tex]$\mathrm{Fe}^{3+}+\mathrm{SCN}^{-} \rightleftharpoons[\mathrm{Fe}(\mathrm{SCN})]^{2+}$[/tex]

Initially

12.015 0

At equilibrium

(12.015 - 4.621 )M 4.621M

Concentration of [tex]$\left[F e^{3+}\right]$[/tex] at equilibrium

The molar heat of fusion of gold is 12.550 kJ mol–1. At its melting point, how much mass of melted gold must solidify to release 235.0 kJ of energy?

Answers

The mass of melted gold to release the energy would be  3, 688. 8 Kg

How to determine the mass

The formula for quantity of energy is given thus;

Q = n × HF

Where n represents number of moles

HF  represents  heat of fusion

To find the number of moles, we have

235.0 = n × 12.550

number of moles = [tex]\frac{235}{12. 550}[/tex] = 18. 725 moles

Note that molar mass of Gold is 197g/ mol

Let's note that;

Number of moles = mass/ molar mass

Mass = number of moles × molar mass

Mass = 18. 725 × 197

Mass = 3, 688. 8 Kg

In this reaction, how many grams of CH4 would be formed from 25 g C?

C + 2H2 → CH4

Answers

33.33 grams of CH4 would be formed from 25 g C.

C + 2H2 → CH4

from given reaction we can say that ,

2 moles of hydrogen is required for 1 mole of carbon and these will react to form 1 mole of methane.

atomic mass of Carbon = 12 gm

Molecular mass of H2 = 2(H)

                                  = 2(1)

                                  =2gm

moles = molecular mass / given mass

for C,

if 12 gm = 1 mole

then 25 gm = ? mole

           =2.083 moles

1 mole of C will produce 1 moles of CH4

so, 2.083 moles of C also will produce 2.083 moles moles of CH4

molecular weight of methane= C+4(H)

                                             = 12+4(1)

                                             = 16 gm

What volume would 20.0 moles of sulfur
dioxide occupy at 75.3 °C with a pressure of
3.50 atm? Answer is in L

Answers

Answer:

163 L

Explanation:

To find the volume, you need to use the Ideal Gas Law. The equation looks like this:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = constant (0.0821 L*atm/mol*K)

-----> T = temperature (K)

Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.

P = 3.50 atm                         R = 0.0821 L*atm/mol*K

V = ? L                                   T = 75.3 °C + 273.15 = 348.45 K

n = 20.0 moles

PV = nRT

(3.50 atm)V = (20.0 moles)(0.0821 L*atm/mol*K)(348.45 K)

(3.50 atm)V = 572.1549

V = 163 L

What is the theoretical yield of bromobenzene in this reaction when 24.8 g of benzene reacts with 52.3 g of bromine?

Answers

Answer:

49.8 g C₆H₅Br

Explanation:

The theoretical yield is the maximum calculated amount of product that can be made from a reaction. To find the theoretical yield, you need to (1) determine the chemical reaction which is taking place, then (2) calculate the molar masses of the relevant reactants and product, then (3) convert grams of each reactant to grams of bromobenzene (using molar masses and mole-to-mole ratio from reaction coefficients), and then (4) determine the limiting reagent and the theoretical yield.

(Step 1)

Bromine = Br₂

Benzene = C₆H₆

Bromobenzene = C₆H₅Br

The balanced equation:

Br₂ + 2 C₆H₆ ----> 2 C₆H₅Br + H₂

(Step 2)

Molar Mass (Br₂): 2(79.904 g/mol)

Molar Mass (Br₂): 159.808 g/mol

Molar Mass (C₆H₆): 6(12.011 g/mol) + 6(1.008 g/mol)

Molar Mass (C₆H₆): 78.114 g/mol

Molar Mass (C₆H₅Br): 6(12.011 g/mol) + 5(1.008 g/mol) + 79.904 g/mol

Molar Mass (C₆H₅Br): 157.01 g/mol

(Step 3)

52.3 g Br₂           1 mole             2 moles C₆H₅Br         157.01 g
----------------- x  ------------------  x  -------------------------  x  ---------------  =
                          159.808 g              1 mole Br₂               1 mole

=  103 g C₆H₅Br

24.8 g C₆H₆         1 mole            2 moles C₆H₅Br          157.01 g
-------------------  x  ---------------  x  --------------------------  x  ---------------  =
                             78.114 g           2 moles C₆H₆             1 mole

=  49.8 g C₆H₅Br

(Step 4)

Because C₆H₆ produces a smaller amount of product than Br₂, it must be the limiting reagent. This means that it will run out before all of the Br₂ is used up. Therefore, the actual theoretical yield of C₆H₅Br is 49.8 grams.

A 3.82 g piece of limestone contains 2.62 g of CaCO3
. Based on these results, what is the mass percentage of CaCO3

Answers

Considering the definition of percentage by mass, the mass percentage of CaCO₃ is 68.59%.

What is mass percentage

The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.

In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.

The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:

[tex]mass percentage=\frac{mass of solute}{mass of solution}x100[/tex]

Mass percentage of CaCO₃

In this case, you know:

mass of CaCO₃: 2.62 gramsmass of limestone: 3.82 grams

Replacing in the definition of mass percentage:

[tex]mass percentage=\frac{2.62 grams}{3.82 grams}x100[/tex]

mass percentage= 68.59 %

Finally, the mass percentage of CaCO₃ is 68.59%.

Explanation:

The empirical formula describes the simplest whole number ratio of each type of atom in a compound. To find this formula, you need to (1) convert grams of each element to moles (via their atomic masses) and then (2) find the ratio of each element (by dividing each molar value by the smallest mole value).

(Step 1)

Atomic Mass (Zn): 65.380 g/mol

Atomic Mass (C): 12.011 g/mol

Atomic Mass (O): 15.998 g/mol

10.40 grams Zn              1 mole
------------------------  x  ------------------------  =  0.159 moles Zn
                                   65.380 grams

   

1.92 grams C               1 mole
---------------------  x  -----------------------  =  0.160 moles C
                                 12.011 grams

7.68 grams O               1 mole
----------------------  x  ------------------------  =  0.480 moles O
                                 15.998 grams

(Step 2)

0.159 moles Zn / 0.159  =  1 atom Zn

0.160 moles C / 0.159  =  1 atom C

0.480 moles O / 0.159  =  3 atom O

The empirical formula is ZnCO₃. Therefore, the value that should be in the space is 1.

When the cooling process takes place superficially and quickly, extrusive igneous rocks are produced, among which are obsidian and basalt, they usually appear after the eruption of a volcano, since the ejected lava solidifies.

Therefore, we can conclude that according to the research, the correct option is 3, Igneous rocks are those formed from a molten product from volcanic activity.
