Find a unit vector perpendicular to the plane through P(2, 1, -1), Q(-1, 1, 2) and R (1, -1, 2)
Let u=(-5, -2, 4), v= (3, 6, -5) and w = (-7, 1, -8)
a) Calculate (u × v).w and hence find the volume of the parallelepiped with adjacent sides u, v, and w.
b) Show that vector (u - projwu) and w are orthogonal.
c) Use the cross product to find the angle between u and w.
Consider the reaction between the Co³+ion and nickel metal:
Co³+ (aq) + Ni(s) → Co²+ (aq) + Ni²+ (aq)
a. Write the half-equations for the reactions of the equation
b. Write the overall balance reaction.

Determine the molar mass of an unknown nonvolatile solute of nonelectrolyte compound raising the boiling point of 150 g of benzene by 0.500°C.
Write Z = 4√(3) e(7π/4)i in algebraic form
A closely wound 0.20m × .20 m square coil of 100 turns is exposed to an external magnetic field of 0.74 T that is perpendicular to the plane of the coil. The coil is then rotated for 10 s until it makes 60 degrees with the magnetic field. Find the average induced electromotive force during the 10 s interval.
A rectangular surface of length 3.25 cm and width 5.25 cm lies on the x-z plane at y=0. What is the flux through this surface due to a uniform magnetic field of 0.65 T directed 60° from the +x-axis?
