I have had NO problems with my printer until yesterday. It is about three years old. Paper is loading uneven and then getting stuck. No matter what I do it looks like one side of the paper is loading faster than the other.
Not significantly. The albedo of the earth is about 35%. The oceans have an albedo of about 10%. Almost 75% of the earth's surface area is covered in water. So, even if you were to place a mirror to cover every landmass on earth, 75% of the planet would still be absorbing solar energy just as it did before.
Maybe you should gargle with hydrofluoric acid. If you have to look it up than you shouldn't mess with any of the chemicals you listed. Beyond what Nick R said, sodium is dangerously explosive when it reacts with water. A small amount will easily blow your uneducated hand off. You would also need a D-rated fire extinguisher that puts out chemical fires. A regular fire extinguisher will cause a horrible and potentially fatal reaction when it touches thermite, potassium or sodium. NOMEX fire suits aren't cheap either. I work for a hazardous waste disposal company and we dispose of the chemicals you listed and quite a few that are a lot worse. Even with years of training accidents happen and you do not want to be disfigured by a chemical burn. I've seen way to many safety videos and read too many memos on some pretty horrific workplace accidents. Those are also EPA and DOT regulated chemicals since they are combustible, flammable and hazardous when wet. Since you live in California you would find out that the laws are not in your favor since you are unlicensed to handle those chemicals. If you're interested in making things go boom than take a chemistry class.
