Consider the reaction CO(g) + 3 H2 (g) ⇌ CH4 (g) + H2O(g) Kc = 7.7×10–23 at 25 °C. 1.50 mol CH4 and 2.50 mol H2O are added to an empty 2.00-L container at 25 °C and allowed to reach equilibrium. What are the equilibrium amounts (in moles) of each species?

The answer is: 1.5 mol CO, 4.5 mol H2 , 1.0 mol H2O, and 2.6×10–21 mol CH4. Please include written work and explanation :-) Thank you!

(a) What is a high impedance relay and when is it used?

(b) A motor with differential protection has a full load current of 200 A. When starting, the motor takes 5 × FL current. The motor is remote from the switchgear which houses one set of CTs and the relay. If the CT ratios are 200/1, the secondary winding resistance is 1.0 ohm and the protection loop lead resistance to the motor is 6 ohms, calculate the minimum relay setting voltage. State what the CT knee point voltage should be.

Two stock solutions will be provided : 1. ~ 2.00 × 10 -5 M quinine sulfate dihydrate in ~ 1.0 M H2SO4 2. ~ 0.150 M KCl

In this stock solution, tell me how to calculate Dilute the stock solutions to make 5 samples with different concentrations of Cl- in the range of 0.0- 0.04 M Concentration of quinine sulfate dihydrate should be near 1.00 × 10-5 M and needs to be the same for all samples Concentration of H2SO4 should be ~ 0.5 M

explain me with equations thank youu

Predict the sign of ΔS for each of the following systems, which occur at constant temperature I. The volume of 2.0 moles of Ne (g) increases from 54 L to 62 L. II. The pressure of 2.0 moles of Ne (g) increases from 0.90 atm to 1.0 atm.

1. a) You have a maximum magnetic field of 1.45 x 10^(-5) Tesla when measured 3.0 cm away from the long section of wire. What is the maximum current that must flow through the wire to create this B-field?

b) You want to make sure you clearly see the time dependence on your phone’s app, decide to design the RC portion of your circuit so that it takes 1.0 seconds for the current to decrease to 10.% of its maximum value. What is the time constant needed?

In Group Project C of Chapter 4, it was shown that the simple pendulum equation:

y''(t) + siny(t) = 0

has periodic solutions when the initial displacement and velocity are small. Show that the period of the solution may depend on the initial conditions by using the vectorized Runge–Kutta algorithm with h 0.02 to approximate the solutions to the simple pendulum problem on for the initial conditions:

a) y(t) = 0.1 y'(t) = 0

b) y(t) = 0.5 y'(t) = 0

c) y(t) = 1.0 y'(t) = 0

1.a What would be the absorbance of 2.63x10^-5M tris at 508nm in a 2.0cm cell if the molar absorptivity of the complex is 1.10x10^4?

Suppose that the iron complex in problem 1a was 1.0% dissociated and the free 1,10 phenantholine had a molar absorptivity of 1.25x10^3 at 508nm

1. Calculate the measured absorbance of the solution. 2. Calculate the percent error in absorbance. 3. What molar concentration of iron complex would be calculated from the measured absorbance if it was assumed that no dissociation occured? 4. What is the percent error in molar concentration of iron complex
