In Graph 1‚ each line of color represents a different level of pH added to the solution. When pH 9 was added‚ it produced the highest rate of reaction (the most oxygen was produced)‚ whereas when the more acidic pH 5 was added‚ the rate of reaction was much slower‚ and less efficient. The higher the oxygen evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal

purpose of this lab experiment is that I will be able to decipher the difference between a chemical and physical change. I will be about to tell whether a chemical change has occurred during the experiment or if it was a physical change and I will be able to answer why it is either one. Procedure: In the lab experiment‚ I mixed different types of chemicals with different background to see if there was a chemical change‚ and also to see what type and why that change occurred.

Fusion as a future energy source Creating Nuclear Fusion could be a break through in finding an alternative source of energy. As of today we do not have the technology to make a nuclear fusion reactor‚ but we could be relying on them for power sometime in the next 30 to 40 years. Nuclear Fusion is created by forcing deuterium (D) and tritium (T) together‚ when forced together their nuclei fuse and then break apart to form a helium nucleus and an uncharged neutron. Most of the excess energy

mixture melting point of a mixture of the two pure compounds. c) Identify an unknown organic compound by determining its melting point and mixture melting point. Procedure and Observations: Using the procedure outlined in Appendix A of the Lab Manual‚ approximately equal samples of p-Nitrophenol and acetanilide‚ which are known to have the same melting range of 113-114 degrees Celcius‚ were taken and inserted into the melting point apparatus. The melting points of the compounds were noted

A nuclear explosion is caused by the release of energy in an atom‚ either through fission or fusion. Fission weapons cause an explosion by the splitting of atomic nuclei. This happens when a neutron collides with the nucleus of an atom. The protons in the nucleus are transformed into a great amount of energy and two or three more neutrons are sent out‚ which go on to split other nuclei. If this continues‚ a chain reaction will occur. The result is a gigantic explosion. To form a chain reaction‚ a
