Consider an ionic compound, mx, composed of generic metal m and generic, gaseous halogen x.
the enthalpy of formation of mx is δhf° = –423 kj/mol. the enthalpy of sublimation of m is δhsub = 119 kj/mol. the ionization energy of m is ie = 469 kj/mol. the electron affinity of x is δhea = –301 kj/mol. the bond energy of x2 is be = 161 kj/mol. determine the lattice energy of mx.

Solve the following simultaneous equation by using an algebraic method (either substitution or elimination) 2x + 3y=-4 4x-y=11

What is the measure of angle 1? a.28 b.152 c.168 d.64

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
