You dissolve a small amount of your copper product in a few mL of water. When you added eight drops of 6 M HCl to the copper complex, you observe that the bright blue color fades and no precipitate forms. Write a net ionic equation for any reaction taking place. Is this compound resistant to attack by acid? How can you tell? If it is helpful, the reaction involved in the experiment is: Cu(H2O)42+ (aq) + SO42- (aq) + 4NH3...
Part I Color changes of Methyl Violet. We will study the following reaction: HMV (aq) + MV (aq) + H* (aq) yellow greenish-blue violet Step 1. Place about 4 mL of distilled water in a regular test tube. Add two drops of methyl violet indicator. Record the color of the solution. Violet Next, add drop by drop, add 6M HCI. This forces equilibrium to be shifted to the left or right-circle the right answer). Adding HCl changes color from to...

In this laboratory exploration various reactions of copper will illustrate these properties. First, begin with copper metal. When concentrated nitric acid is added, dramatic changes occur and the metal dissolves forming a brightly colored copper ion-containing solution.

However, if diluted...
1)In many species of flowering plants, the gene(s) responsible for flower color are incompletely dominant. A cross of a red rose and a blue rose will create what color(s) of flowers? a red b blue c purple d both red and blue 2)Plant height in pea plants is controlled by a single gene. T is tall while t is short. Match the genotype on the left with possible progeny on the right. Note you are only given ONE genotype and...
