How does adding oxygen (o2) to this reaction change the equilibrium? 2so2(g) + o2(g) ⇌ 2so3(g) a. the equilibrium shifts right to produce more so3 molecules. b. the equilibrium shifts left to produce more o2 molecules. c. the equilibrium shifts right because of decreased collisions between so2 and o2 molecules. d. the equilibrium shifts left with an increase in so2 and o2 molecules. e. the equilibrium shifts left because of increased collisions between so2 and o2 molecules.

According to le chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress. normalizes the stress. increases the stress. changes the stress.

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
