always occur at the anode. My experiment is aimed at testing the corrosion of 2 different types of nails in a certain molar solution of salt water in anticipation of determining which of the two would be more suitable for beachside residencies. I hypothesized that the iron nails would almost double in content of rust as the molarity of the solution they’re soaked in increases. The galvanized nails hopefully will end up with limited amounts of rust in all solutions. The activity series plays a major

experiment on four different types of metals and four different liquids. I will be using a penny‚ nail‚ paper clip and a needle as my four metals. My four liquids will be vinegar‚ beach‚ lemon water and salt water. To get started‚ the metal contents should be established. Today’s pennies are mostly made of zinc with a thin layer of copper overcoating. A nail is a form of carbon steel or black iron. Paper clips are made from a low grade steel. A needle

Interaction between the hammer and nail A hammer exerts a force on the nail and drives it into a board . But this is not the only force present for there must also be a force exerted on the hammer to stop it in the process. What exerts this force? The nail does. Newton reasoned that while the hammer exerts a force on the nail ‚ the nail exerts a force on the hammer. So‚ the interaction between the nail and the hammer‚ there is a pair of forces ‚ one acting on the nail and the other acting on the hammer
