Another reason I fall into the habit of biting my nails is nervousness. Once I was waiting for a job interview ‚ I noticed that my nails where getting shorter and shorter without my intention.

poorly trimmed nails. According to the Cleveland Foot and Ankle Clinic‚ "Cutting toenails properly goes a long way toward the prevention of ingrown toenails. Using a safety nail clipper‚ cut the nails straight across‚ so that the nail corner is visible. If you cut the nail too short‚ you are inviting the nail corner to grow into the skin." The corners of the nail should not be cut out‚ except by a podiatrist. Have a home care aid regularly assist with the trimming and care of the nails can also go a

Introduction When iron is mixed to Copper (Ⅱ) Chloride; the product will be copper and iron chloride. However‚ in this experiment‚ we do not have the information of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally

A potato battery is a type of electrochemical cell. An electrochemical cell converts chemical energy into electrical energy. In the potato battery‚ there is a transfer of electrons between the zinc coating the galvanized nail that will be inserted into the potato and the copper wire that will be inserted another part of the potato. The potato conducts electricity‚ yet keeps the zinc ions and copper ions separate‚ so that the electrons in the copper wire are forced to move (generate current). It’s
