draw an energy level diagram for Hydrogen starting at n=2 and ending at n=6. (n=1 transitions are high-energy transitions and emit in the ultra-violet region). Draw all emissions arrows (arrows pointed down) for each transition going to a final state of n=2.
Assuming that the process is working as intended, draw and label the flowchart, do the degree-of-freedom analysis, and estimate the molar flow rate (lb-mole/h) of the humidified outlet air
What mass of calcium can be produced by this process if a current of 5900 A is applied for 55 h? Assume that the electrolytic cell is 60 % efficient.
What is the boiling point of a mixture composed of 95.0 g HOCH2CH2OH (ethylene glycol) and 205 g H2O? The boiling point elevation constant for H2O is 0.512 °C/m.
Describe what will be observed when a mixture of composition x_b=0.8 is heated, at each stage giving the number, composition, and relative amounts of the phases present.
Kp for the reaction of SO2(g) with O2 to produce SO3(g) is 3 × 1024 . Calculate Kc for this equilibrium at 25ºC. (The relevant reaction is 2SO2(g) + O2(g) 2SO3(g).)
To what volume should you dilute 95mL of a 12.0M H2SO4 solution to obtain 1.80M H2SO4 solution
Suppose that 50.0g of Zinc and 50.0g of Iodine are used to form Zinc (II) Iodide. Answer the following questions: (A) What is the limiting reagent?
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.
You are given the chemical reaction: 4AsF3 + 3C2Cl6 -> 4AsCl3 + 3C2Cl2F4.If 1.3618 moles of AsF3 are allowed to react with 1.000 mole of C2Cl6.
The steel bomb of bomb calorimeter, which has a volume of 75 mL, is chaged with oxyen to a pressure of 145 atm at 22 C. Calculate the moles of oxygen in the bomb. Calculate the grams of oxygen in the bomb.
