The nitrogen oxide (NO) molecule has a bond length of 140 pm. Calculate the dipole moment, in Debyes, that results if the charge

Cloud [144]

Answer:

Explanation:

Dipole moment = charge x separation of charges

= (2 x 1.6 x 10⁻¹⁹ ) x ( 140 x 10⁻¹² ) coulomb-metre

= 448 x 10⁻³¹coulomb-metre

1 debye = 3.33 x 10⁻³⁰coulomb-metre

Dipole moment in debye = 448 x10⁻³¹ / 3.33 x 10⁻³⁰debye

= 448 x10⁻³¹ / 33.3 x 10⁻³¹

= 13.45 debye

What can you infer if the fossil of a marine organism is found in an area that is now dry land?

Deffense [45]

Answer:

Fossils also help us to infer why dinosaurs and other organisms became extinct. Fossils tell us that there was a mass extinction at the time of the dinosaurs. They died out about 65 million years ago, along with more than half of all the other animal and plant species. ... Without plants, dinosaurs could not survive.

Suppose you have designed a new thermometer called the x thermometer. On the x scale the boiling point of water is 129 ?x and th

djyliett [7]

(x1,y1) (x2,y2)

(32,15) (212,135)

y = mx + b

m=(y2-y1)/(x2-x1)

m=.66667

y = .66667*(x) + b

Plug in #s to test for b value

15 = .66667*(32) + b

b = -6.334

y = mx + b

y = .6667*(x) + (-6.334)

F = .6667*(F) + (-6.334)

F = (.6667*(F) = -6.334

(F - .6667F) = -6.334

F(1 - .6667) = -6.334

F = -19

ThermX = F @ -19 degrees
