POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ the

Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a

changes in the pH of a solution (5 points) 2. Cooks use baking soda to make cakes light and fluffy. You might have used baking soda yourself. Baking soda is NaHCO3. A 0.1 M solution of baking soda in water has a [H+] of about 4.0 × 10–9. (You may prefer to think of the hydronium ion concentration‚ [H3O+]‚ as 4.0 × 10–9.) Write the formula for the calculation of pH‚ and then show each step as you calculate the pH of a 0.1 M solution of baking soda. Answer: pH = -log [H⁺] ←←[log without a specified base

weight in water. Fuller’s earth litter can get rid of some of the ammonia odor by trapping the positively charged ammonium ions that are formed when water in urine penetrates the ammonia. To improve odor control the cat litter used things such as baking soda to absorb the smells‚ and antibacterial agents to kill odor- causing bacteria. The only thing wrong with Fuller’s earth was that it would leek to the bottom and sit there‚ so making it tedious to clean the cat litter lot but less often them sand

Mummification is the preservation of body. Both animals and humans were preserved. There were different methods of mummification. Some were frozen‚ dried‚ and some were wet. Mummification can happen naturally or it can be done on purpose. Mummies were made on purpose
