Methane reacts with chlorine to produce methyl chloride and hydrogen chloride. Once formed, the methyl chloride may undergo further chlorination to form methylene chloride (CH2Cl2), chloroform, and carbon tetrachloride. A methyl chloride production process consists of a reactor, a condenser, a distillation column, and an absorption column. A gas stream containing 80.0 mole% methane and the balance chlorine is fed to the reactor. In the reactor a single-pass chlorine conversion of essentially 100% is attained, the mole ratio of methyl chloride to methylene chloride in the product is 5:1, and negligible amounts of chloroform and carbon tetrachloride are formed. The product stream flows to the condenser. Two streams emerge from the condenser: the liquid condensate, which contains essentially all of the methyl chloride and methylene chloride in the reactor effluent, and a gas containing the methane and hydrogen chloride. The condensate goes to the distillation column in which the two component species are separated. The gas leaving the condenser flows to the absorption column where it contacts an aqueous solution. The solution absorbs essentially all of the HCl and none of the CH4CH4 in the feed. The liquid leaving the absorber is pumped elsewhere in the plant for further processing, and the methane is recycled to join the fresh feed to the process (a mixture of methane and chlorine). The combined stream is the feed to the reactor.
Required:
a. Choose a quantity of the reactor feed as a basis of calculation, draw and label a flowchart, and determine the degrees of freedom for the overall process and each single unit and stream mixing point. Then write in order the equations you would use to calculate the molar flow rate and molar composition of the fresh feed, the rate at which HCl must be removed in the absorber, the methyl chloride production rate, and the molar flow rate of the recycle stream. Do no calculations.
b. Calculate the quantities specified in Part (a), either manually or with an equation-solving program.
c. What molar flow rates and compositions of the fresh feed and the recycle stream are required to achieve a methyl chloride production rate of 1000 kg/h?

How many atoms are in 56 grams of silicon?
Answers
Answer:
[tex]atoms=1.2x10^{24}atomsSi[/tex]
Explanation:
Hello there!
In this case, by considering the mass-mole-particles relationships, it is possible to compute the atoms of silicon by firstly computing the moles via its atomic mass (28.1 g/mol):
[tex]mol=56gSi*\frac{1molSi}{28.1gSi} =2.0molSi[/tex]
Next, via the Avogadro's number, we can compute the atoms of silicon:
[tex]atoms=2.0gSi*\frac{6.022x10^{23}atomsSi}{1molSi}\\\\atoms=1.2x10^{24}atomsSi[/tex]

structure of 2,3-dimethylheptane
Answers
Answer:
Please find the structure of the hydrocarbon in the attachment section and details on how to draw it in the explanation section.
Explanation:
Heptane is a member of the alkane group, which has a general formula of CnH2n+2. If n in heptane is 7, this means that the chemical formula for heptane will be C7H16 i.e.
= C7H2(7) + 2
= C7H14+2
= C7H16
C7H16 is the chemical formula for heptane, which is a linear hydrocarbon with 7 carbon atoms and 16 hydrogen atoms. However, in the name of the hydrocarbon compound given in the question: 2,3-dimethylheptane;
- Two methyl groups (CH3) has a substituted two hydrogen atoms specifically at carbon 2 and 3 respectively. Therefore, the new chemical formula of 2,3-dimethylheptane will be: C7H14(CH3)2
Please find the structural formula of the compound; 2,3-dimethylheptane as an attachment.

If H2O is removed from this reaction, what will happen? 2H2 + O2 + 2H20 O A. The product-favored reaction will stop. B. The reactants will react to produce more H2O. C. The equilibrium will not change. D. The reaction will be reactant-favored.
Answers
Answer:
B. The reactants will react to produce more H₂O
Explanation:
Given the reaction
2H₂+O₂→2H₂O
A decrease in the amount of H₂O will cause the reaction to produce more H₂O. When you change something, the reaction seeks to undo that change.

If you are given 64.0 grams of CH4, how many grams of H2O are made
Answers
Answer:
144 g of H₂O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Next, we shall determine the mass of CH₄ that reacted and the mass of H₂O produced from the balanced equation. This can be obtained as follow:
Molar mass of CH₄ = 12 + (4×1)
= 12 + 4 = 16 g/mol
Mass of CH₄ from the balanced equation = 1 × 16 = 16 g
Molar mass of H₂O = (2×1) + 16
= 2 + 16 = 18 g/mol
Mass of H₂O from the balanced equation = 2 × 18 = 36 g
SUMMARY:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Finally, we shall determine the mass of H₂O produced by the reaction of 64 g of CH₄. This can be obtained as follow:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Therefore, 64 g of CH₄ will react to produce = (64 × 36)/16 = 144 g of H₂O.
Thus, 144 g of H₂O were obtained from the reaction.

An empty graduated cylinder has a mass of 42.91 g. When filled with 40.00 mL of an unknown liquid, it has a mass of 103.26 g. Calculate the density of the unknown liquidz
Answers
Answer:
1.511g/mL
Explanation:
To find density, we can use the equation
[tex]d=\frac{m}{V}[/tex]
We have V (40mL) To find m (mass), we must subtract as such:
[tex]103.36-42.91=60.45[/tex]
60.45 grams is the mass of the unknown liquid.
Now, we plug the values we have into the density equation.
[tex]d=\frac{60.45g}{40.00mL} \\\\ d=1.511\frac{g}{mL}[/tex]
The density of the unknown liquid is 1.51 g/mL
Density can be defined as the mass of an object per unit volume of the object.
[tex]Density = \frac{mass}{volume}[/tex]
To solve the question given above, we'll begin by calculating the mass of the unknown liquid. This can be obtained as follow:
Mass of empty cylinder = 42.91 g
Cylinder + unknown liquid = 103.26 g
Mass of unknown liquid =?Mass of unknown liquid = (Cylinder + unknown liquid) – (Mass of empty cylinder)
Mass of unknown liquid = 103.26 – 42.91
Mass of unknown liquid = 60.35 gFinally, we shall determine the density of the unknown liquid. This can be obtained as follow:
Mass of unknown liquid = 60.35 g
Volume of unknown liquid = 40 mL
Density of unknown liquid =?Density = mass / volume
Density = 60.35 / 40
Density of unknown liquid = 1.51 g/mLTherefore, the density of the unknown liquid is 1.51 g/mL

Determine the number of moles of air present in 1.35 L at 750 torr and 17.0°C. Which equation should you use? P equals StartFraction n R T over V EndFraction. n equals StartFraction R T over P V EndFraction. n equals StartFraction P V over R T EndFraction.
Answers
Answer:
0.056 moles air
Explanation:
P·V = n·R·T => n = P·V/R·T
P = 750 Torr = 750 mmHg = (750mm/760mm/atm) = 0.9868 Atm
V = 1.35 Liters
R = 0.08206 L·atm/mole·K
T = 17°C = (17 + 273) K = 290K
n = (0.9868atm)(1.35L)/(0.08206L·atm/mole·K)(290K) = 0.056 moles air

Cars rust because when metal comes into contact with water or some sort of water form, it will make the surface wet. If the metal is wet for too long, it will start to soak up the water, therefore making it rusty. The salt will also rust a car. It does this because the mix of carbon dioxide and oxygen in the salt will eat away at the car, making it rust faster. Hope this helps!
The atomic radius _________________ down a group. Explain why
Answers
Across a period, effective nuclear charge increases as electron shielding remains constant. A higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius.
Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
