For each of the following statements, determine whether the statement is true or false. If you say the statement is true, explain why and if you say it is false, give an example to illustrate.
(a) If {u, v} is a linearly independent set in a vector space V, then the set {2u + 3v, u + v} is also a linear set independent of V.
(b) Let A and B be two square matrices of the same format. Then det (A + B) = det (A) + det (B).
(c) It is possible to find a non-zero square matrix A such that A^2 = 0.
(d) Let V be a vector space. If {v1, v2,. . . , vn} (with n ≥ 1) is a base of V and if {w1, w2,. . . , wm} is a generator system of V then n ≤ m.

Determine whether each of the following statements is true or
false. If the statement is false, modify and rewrite it so that it
is a true statement.
a. When a molecule has two, degenerate, “infrared active”,
vibrational modes, the two vibrational modes will show absorptions
at different frequencies in the infrared spectrum.
b. For a given substance, strong intermolecular forces between
molecules of the substance can cause peak broadening of some of the
absorptions in the infrared spectrum of the...

True or False questions. Determine whether or not each of the
following statements is true. If a statement is true, prove it. If
the statement is false, provide a counterexample and explain how it
constitutes a counterexample. Diagrams can be useful in explaining
such things.
