Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations

Pepper‚ the time the meat spent in the Dr. Pepper‚ and the original mass of meat. The results after being in the Dr. Pepper is the pork chop 16.1 grams‚ chicken breast 13.5 grams‚ beef roast 13.1 grams. The results of the distilled water were and vinegar were.The hypothesis which stated that the mass of the pork chop will increase was supported because the results was 16.1 grams and the chicken breast and beef roast results came out to the thirteens. If the experiment was repeated the type of meat

Elephant’s Toothpaste Mix two solutions together and you get an amazing eruption of foam. (Submit Review) Mix two solutions together and you get an amazing eruption of oxygen-filled foam that looks like a giant stream of toothpaste... or elephant toothpaste. The classic reaction is a favorite of chemistry teachers who have access to these chemicals that you will not find around the house.
