For the given reaction, according to Le -Chatlier principle adding a catalyst will bring the reaction to the right. Removing the hydrogen gas shift the equilibrium to the left and increasing pressure also shift to right.
What is Le -Chatlier principle ?According to this principle, when some a disorder is affecting the equilibrium of the system. The system balanced the factors which created the disorder and make a new equilibrium.
A catalyst always helps to proceed the reaction in the forward direction. Thus adding a catalyst shift the equilibrium to the right.
If any reactant or produced is removed from the system, the system shifts to the equilibrium to that direction in which they are producing. Removing hydrogen gas will then shift the reaction to the right to produce more hydrogen.
Increasing pressure shift the equilibrium to those direction in which the number of number of moles of gases decreases. Hence, the reaction shifts to the right here.

a) Drive an expression to find a pressure of methane gas at point B b) If the temperature of methane is 100 F, Calculate pressure of
methane gas at point B.
c) Calculate pressure of oil at point C.
PA = 1, 000 psig
[3]- If the water is pumped down one well and the displaced oil which flows up through well exit (see the fig below), drive an expression to find a pressure of inlet water Pw needed to displace oil when the water/oil interfacial tension σ is applied.
Velocity is a vector quantity that describes the rate and direction of an object's motion.
a) The velocity of the fluid:
V = 35 gpm / (π * (1.05 in)^2 / 4) = 7.09 ft/s
b) Reynolds number:
Re = (62.3 lbm/ft^3 * 7.09 ft/s * 1.05 in) / (1.2 cP) = 4,211.9
[2]- a) Expression to find pressure of methane gas at point B:
PB = PA + rgh
b) Pressure of methane gas at point B:
PB = 1,000 psig + (0.072 lbm/ft^3 * 32.2 ft * 0.0689 psia/ft) = 1,233.5 psig
c) Pressure of oil at point C:
PC = PB - 0.433 psia/ft * 32.2 ft = 1,093.3 psig
[3]- Expression to find pressure of inlet water Pw needed to displace oil:
Pw = PC + (σ / r) * (h2 - h1)
Pw = 1,093.3 psig + (σ / 0.072 lbm/ft^3) * (32.2 ft - 0 ft) = 1,093.3 psig + (σ / 0.072 lbm/ft^3) * 32.2 ft.
What is velocity?
Velocity is a vector quantity that describes the rate and direction of an object's motion. It is commonly represented by the symbol 'v' and is measured in meters per second (m/s). Velocity includes both the speed and the direction of the object. For example, if an object is moving north at 10 m/s, its velocity would be 10 m/s north.

What is refraction?The direction of the light changes as it passes through the air-water barrier. Refraction is the name for this phenomenon. Filling a glass with water and inserting a straw will make it simple to see. It will seem as though the straw is shattered.
Because light travels at a different speed in air and water, refraction takes place. The electromagnetic properties of a specific medium, which differ for air and water, determine the speed at which a light wave propagates in that medium. The speed of light in the air is very near to the vacuum's speed of light, which is 3*108 m/s. The speed of light is slower underwater. Consequently, The direction of the light changes as it passes through the air-water barrier. Refraction is the name for this phenomenon. Filling a glass with water and inserting a straw will make it simple to see. It will seem as though the straw is shattered.

A sample of helium was compressed at 35 °C from a volume of 0.5 L to 0.25 L where the pressure is 500 mmHg. What was the original pressure?
Answer:
The ideal gas law is a formula that relates the pressure, volume, temperature, and number of moles of a gas. It can be expressed as:
PV = nRT
where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the gas constant, and T is the temperature in Kelvin.
Since the number of moles and the temperature are constant in this problem, we can rearrange the formula to solve for the pressure:
P = (nRT) / V
Plugging in the known values, we get:
P = (nRT) / V
= (n * R * (35 + 273)) / 0.25 L
= (n * R * 308 K) / 0.25 L
We are given that the pressure is 500 mmHg and the volume is 0.25 L at this pressure, so we can set these equal:
500 mmHg = (n * R * 308 K) / 0.25 L
Solving for n, we get:
n = (500 mmHg * 0.25 L) / (R * 308 K)
We know that the pressure and volume of the gas at its original state are what we are trying to solve for. Let's call the original pressure P_0 and the original volume V_0. We can then express the relationship between the original and final state of the gas as:
P_0 * V_0 = n * R * T
Substituting the expression we found for n and the known values, we get:
P_0 * V_0 = ((500 mmHg * 0.25 L) / (R * 308 K)) * R * 308 K
Solving for P_0, we get:
P_0 = (500 mmHg * 0.25 L) / (R * 308 K) * (R * 308 K) / V_0
= (500 mmHg * 0.25 L) / (V_0)
Since V_0 = 0.5 L, we can substitute this value to get:
P_0 = (500 mmHg * 0.25 L) / (0.5 L)
= 500 mmHg / 2
= 250 mmHg
Therefore, the original pressure of the gas was 250 mmHg.

The pH value of 500 mL of an aqueous solution of 0.005 mole HCl is 2
How do I determine the pH of the solution?We'll begin our calculations by obtaining the molarity of the solution. Details below:
Volume of solution = 500 mL = 500 / 1000 = 0.50 LMole of HCl = 0.005 moleMolarity = ?Molarity = mole / volume
Molarity = 0.005 / 0.50
Molarity = 0.01 M
Next, we shall obtain the concentration of the hydrogen ion, H⁺ in the solution. Details below:
HCl(aq) <=> H⁺(aq) + Cl¯(aq)
From the balanced equation above,
1 mole of HCl contains 1 mole of H⁺
Therefore,
0.01 M HCl will also contain 0.01 M H⁺
Thus, the concentration of the hydrogen ion, H⁺ in the solution is 0.01 M
Finally, we shall determine the pH of the solution. Details below:

A solid-state battery is a battery technology that uses solid electrodes and a solid electrolyte, instead of the liquid or polymer gel electrolytes which are found in lithium-ion or lithium polymer batteries.
While solid electrolytes were first discovered in the 19th century, several drawbacks have prevented it's widespread application. Developments in the late 20th and early 21st century have caused renewed interest in solid-state battery technologies, especially in the context of electric vehicles, starting in the 2010s.
Solid-state batteries can provide potential solutions for many problems of liquid Li-ion batteries, such as flammability, limited voltage, unstable solid-electrolyte interphase formation, poor cycling performance and strength.

Combustion of 1.125 of an unknown compound containing carbon, hydrogen, and oxygen resulted in 1.649g of CO2 and 0.675g of H2O. If the molar mass is 180g/mol What is the molecular formula?
CxHyOz + O2 → CO2 + H2O
The molecular formula of the unknown compound, given that it contains carbon, hydrogen, and oxygen is C₆H₁₂O₆
How do I determine the molecular formula?First, we'll begin by obtaining the mass of carbon, hydrogen and oxygen. Details below:
For Carbon
Mass of CO₂ = 1.649 gMolar mass of CO₂ = 44 g/mol Molar of C = 12 g/mol Mass of C =?Mass of C = (12 / 44) × 1.649
Mass of C = 0.45 g
For Hydrogen
Mass of H₂O = 0.675 gMolar mass of H₂O = 18 g/mol Molar of H = 2 × 1 = 2 g/mol Mass of H =?Mass of H = (2 / 18) × 0.675
Mass of H = 0.075 g
For Oxygen
Mass of compound = 1.125 gMass of C = 0.45 gMass of H = 0.075 gMass of O =?Mass of O = (mass of compound) - (mass of C + mass of H)
Mass of O = 1.125 - (0.45 + 0.075)
Mass of O = 0.6 g
Next, we shall determine the empirical formula. details below:
C = 0.45 gH = 0.075 gO = 0.6 gEmpirical formula =?Divide by their molar mass
C = 0.45 / 12 = 0.0375
H = 0.075 / 1 = 0.075
O = 0.6 / 16 = 0.0375
Divide by the smallest
C = 0.0375 / 0.0375 = 1
H = 0.075 / 0.0375 = 2
O = 0.0375 / 0.0375 = 1
Thus, the empirical formula of the compound is CH₂O
Finally, we shall determine the molecular formula. Details below:
Molar mass of compound = 180 g/molEmpirical formula = CH₂OMolecular formula =?Molecular formula = empirical × n = mass number
[CH₂O]n = 180
[12 + (2×1) + 16]n = 180
30n = 180
Divide both sides by 30
n = 180 / 30
n = 6
Molecular formula = [CH₂O]n
Molecular formula = [CH₂O]₆
Molecular formula = C₆H₁₂O₆
