When aqueous solutions of potassium carbonate and aluminum chloride are combined, solid aluminum carbonate and a solution of potassium chloride are formed. The net ionic equation for this reaction is: (Use the solubility rules provided in the OWL Preparation Page to determine the solubility of compounds.)

How does the principle of electromagnetism explain the interaction between earth’s magnetic field and the solar wind?

The arrangement of particles is most ordered in a sample of

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
