Carbon dioxide, CO2, in the atmosphere is considered a major contributor to global warming. Its Lewis structure is simple, as shown below. The nonbonding electrons in this Lewis structure have not been included. How many pairs of nonbonding electrons are missing in the provided Lewis structure for carbon dioxide? (note, you are asked for pairs of nonbonding electrons for the entire molecule, not the total individual nonbonding electrons).

A 42.5×42.5 cm horizontal metal plane is uniformly charged to +70.9 nC. What is the electric field strength 7.80 mm above the center of the electrode?

We have three identical metallic spheres A, B, C. Initially sphere A is charged with charge 4Q, while B and C are neutral. First, sphere A is brought into contact with sphere B and then separated from it. After that, sphere A is brought into contact with sphere C and then separated from it. Finally, sphere A is brought into contact with sphere B again, and then separated from it. What is the final charge of sphere A
