Consider the reaction N2 + O2=2 NO. At 1800 °C, this reaction has an equilibrium constant of 1.2 x 10-4. During the course of the reaction, a
sample of the reaction mixture is taken, and the concentrations of
each component are found to be as follows: [N2] = 0.045 mol dm-3,
[O2] = 0.071 mol dm-3, and [NO] = 0.004 mol dm-3. In which direction
must the reaction proceed for it to reach equilibrium?
=
Select one:
O The reaction is already at equilibrium.
O The reaction must proceed from left to right.
O The reaction must proceed from right to left.

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
