(1.72 x10–6 g/0.100 L)(1 mol/97.5 g) = 1.76 x10–7 mol/L (iii) Calculate the value of the solubility-product constant‚ Ksp‚ for Cu(OH)2 at 25 °C. Ksp = [Cu 2+][OH –]2 = [1.76 x10–7][3.53 x10–7]2 = 2.20 x10–20 (b) The value of the solubility-product constant

04/02/14 Date Submitted: 04/15/14 Name: Lisa Jacoby Title: Physical and Chemical Properties Purpose: Investigating the chemical properties of pure chemical substances as well as exploring the physical properties of pure chemical substances Procedure: 1. I half-filled one well of a 24-well plate with 6M HCl and half-filled a second well of the 24-well plate with 6 M NaOH. I then sucked up these chemicals into their labeled pipets. I then set aside for later 2. I performed the following

Experiment 1: Observations of Chemical Changes Purpose: To observe the macroscopic changes that occur in chemical reactions and attempt to interpret the microscopic changes of the atoms and molecules that allow for the macroscopic changes to happen; and to associate these chemical properties with household products. Also‚ it is to learn the importance of how to separate mixtures into their component substances by solubility. Procedure: Before starting with the official experiment‚ it was important

2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # | Chemicals | Observations | |

Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility

a senior credit representative of Joyce Chemical Company. My task in this case is to look into Eliot Manufacturing and to see if we should continue or terminate our relationship with them. If we were to continue‚ the choices would be to either have them in a program to reduce their accounts payable or to tolerate gradual increases in credit. After doing an analysis on Mr. Pound and the Eliot Manufacturing Company‚ I would recommend that Joyce Chemical Company should terminate their relationship

be analyzed by the characters in the movie “Victor Victoria.” The movie makes it clear that non-verbal messages are effective in carrying out messages. The audience is still able to tell what a character is feeling or trying to express without any verbal emotions. This movie takes place in Paris in the 1950s. One of the main characters‚ Victoria Grant‚ who is an artiste has high hopes in becoming a musical sensation. When we first see Victoria‚ she’s in the process of auditioning for a nightclub
