mole ratio? 2. What piece of information is needed to convert grams of a compound to moles of the same compound? 3. Phosphine (PH3) can be prepared by the hydrolysis of calcium phosphide‚ Ca3P2: Ca3P2 + 6 H2O 3 Ca (OH)2 + 2 PH3 a) One mole of Ca3P2 produces 2 mol of PH3. b) One gram of Ca3P2 produces 2 g of PH3. c) 3 moles of Ca(OH)2 are produced for each 2 mol of PH3 produced. d) The mole ratio between phosphine and calcium phosphide is 2 mol PH31 mol Ca3P2

Les Miserables: Analysis of the Characters Philosophy 1C December 06‚ 2013 Abstract Four characters from the 1998 film Les Miserables are analyzed. Jean Valjean‚ Fantine‚ the Bishop‚ and Inspector Javert are the characters for this study. Each character’s moral decision making will be examined. Using the consequentialist and nonconsequentialist theories discussed in the book Ethics: Theory and Practice‚ a particular theory will be matched to each character with supporting

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead

Chemical Periodicity Gorospe‚ Jheremy Alden B. ____________________________________________________________________________________ ABSTRACT The experiment Chemical Periodicity was demonstrated by using different samples of Group IA‚ Group IIA and Group IVA elements. We placed each of the samples in each test tubes and the physical state‚ color‚ and appearance was identified. We determined the solubility of the elements by using distilled water. We used red and blue litmus paper for the Group

For these next two assignments I have some specific goals for what I wish to accomplish in paper. My main goals are to pick a topic that is original and actually controversial. In my CAS 100 class when the class was assigned with to do a policy speech I aimed to find a topic which I was fairly ignorant on‚ in order to challenge myself. I decided to chose the topic of gentrification‚ since I felt it was a topic that many‚ including myself‚ weren’t very aware of the occurrence. Others on the other
