Chem Stuff

100

What is the most electronegative element?

F

200

How are ionic, covalent and metallic bonds different?

e^- sharing (loss/gain, shared, donated)

300

What 4 things do you need for a working electrochemical cell?

Cathode, anode, electrical connection, salt bridge

400

What are the products of the reaction between sodium phosphate and bismuth (III) chloride in water?

**Include phases :D**

Na₃PO₄ (aq) + BiCl₃ (aq) -> 3NaCl (aq) + BiPO₄ (s)

500

What two temperatures is the modern Celsius scale based on? 

Absolute zero (-273.15) and triple point of water at 1atm (0.01)

Math/Physics Stuff

100

Find the derivative of sin²(x)

2sin(x)cos(x)

200

What type of collision does not conserve energy?

Inelastic 

300

Solve the following ODE:

 y'' + 36y = 0

y = c₁sin(6x) + c₂cos(6x)

400

How do you combine two parallel resistors to get an equivalent resistance? 

1/R_new = 1/R₁ + 1/R₂

500

Find the derivative of x^x

x^x(1 + ln(x))

*treat x^x as e^ln(x^x) --> e^(xln(x))

CHE Stuff 1

100

What variables does Antoine's equation relate?

vapor pressure and temperature

200

What is the matlab command to reduce a matrix?

rref(A)

300

What metals are in catalytic converters?

Pd, Pt, Rh (get 2 of the 3)

400

Name 2 of the dimensionless parameters in fluid mechanics and heat & mass transfer

Re, Pr, Ra, Nu, Bi, Gr

500

Name 4 of Pauling's rules of crystal chemistry

Polyhedra are shared at corners, sometimes at edges, never at faces; Charge is conserved; # of different constituents is small; Radius ratio determines coordination number; Large charges tend not to be shared.

CHE Stuff 2

100

What variables does an equation of state relate?

Pressure temperature & volume

200

Two 100 kg/s streams of EtOH & MeOH are combined into one product stream. Stream 1 is 60% EtOH, stream 2 is 20% EtOH. What is the MeOH composition of the exiting stream?

60% at 200 kg/s

300

What is an azeotrope?

A mixture composition that cannot be separated with distillation

400

What is fugacity?

"Idealized pressure" for non-ideal gases & conditions. Using fugacity as the operating pressure makes the gas act ideal.

500

How can you break an azeotrope?

Shift system pressure, separate using another property (solubility, size, molecular interactions)

idk
