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.

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

Amanda Nava Term Definition Scenario Controlling When a financial manager makes sure that every department in the organization is following the plans that have been set. When viewing feedback reports from 8 months ago in comparison to those written 2 weeks ago week the manager was able to see that more money was being spent on man hours in her department even though patient flow had actually decreased. By this valuation she realized she needs to adjust employees work schedules and do some changing

temperature and times and iodine was used as indicator of presence of starch. During the experiment we observed that bacterial amylase had faster enzymatic activity than fungal amylase; bacterial amylase achieved 100% hydrolysis at 40°c and 60°c at 2 minutes time and fungal amylase achieved partial hydrolysis at 60°c at 4 minutes time. With all of this we can say that the optimal temperature for fungal and bacterial are almost the same‚ but bacterial have faster amylase activity than fungal and

Discussion Question #1 Singer argues that there is no moral justification for denying moral consideration to animals. Can you think of a reason why our moral consideration should include all humans regardless of their level of cognitive ability‚ yet denied to non-human animals simply because they have lower levels of cognitive abilities (though still higher in some cases than those of human infants and some mentally disabled humans)? What response might he have to your way of drawing the line between
