(Only the ones who were doing the experiment) 50mL of water was placed in the 100mL beaker and heated until boiled. And the boiled water will be used as the water bath. The lab marker was used to make 3 marks (1 cm apart). 1.0 M copper (II) nitrate was added to the first mark on the test tube. 1.0 M sodium hydroxide (NaOH) was added up to the second mark on the test tube.

he invented the walking pedicle tube‚ the Epithelial Outlay‚ and learned many important lessons along the way. He used the principles from the self-graphing nose operation performed by Gaspare Tagliacozzi‚ in the 16th century. The operation would include taking skin from the underside of the arm and then grafting it to the nose. However‚ the patient would be immobilized causing a lot of discomfort. Gillies modified this method and made the walking pedicle tube. A tube of flesh was created by leaving

Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate? The purpose of
