Solve the following ODE:

 y'' + 36y = 0

y = c1sin(6x) + c2cos(6x)

300

What metals are in catalytic converters?

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

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)

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

1/Rnew = 1/R1 + 1/R2

400

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

Re, Pr, Ra, Nu, Bi, Gr

400

What is fugacity?

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

Find the derivative of x^x

x^x(1 + ln(x))

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

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.

How can you break an azeotrope?

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