    Obeying the law is a general moral obligation. Usually‚ laws are written from societal ethical codes; therefore the law can embody morality. Obeying the law usually implies the greatest good for the greatest number of people and therefore complies with Mill’s utilitarianism. Especially if the law reflects general morality or protects people from pain‚ such as the admonition against murder‚ utilitarian theorists would argue that obeying the law is a general moral obligation. However‚ there are certain

    In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab.

The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

    Buffer Post Lab Calculation 1. We added too much NaOH to our buffer 1 solution. The original pH was 5.32‚ with 10mL of buffer and 10mL of DI water. We added 5mL of NaOH and the pH changed to 12.12. If 5 mL changed the pH by about 7‚ then we predict that about 2 mL of NaOH would change the pH by about 2. This prediction is based on the fact that 2.5mL is half of 5mL‚ and 3.5 is half of 7‚ so adding a little less than 2.5mL would give us a difference of about 2. For the buffer 2 solution‚ the original
