1. Dinitrogen tetraoxide (colorless gas) is converted to nitrogen dioxide (dark reddish brown gas) and is endothermic in the forward direction: A. Write a balanced equation. B. If a closed container containing a mixture of these two gases at equilibrium is a light brown in color when it is at room temperature (20.0°C), what change would you expect to observe if the container is placed in boiling water (100.0 °C)? c. If a closed container containing a mixture...

than other labs. These are toxicity, volatility, and flammability. We routinely use toxic organic solvents like methanol and acetone that are volatile (have low boiling points), but even solid organic materials can produce vapors that may be toxic. Furthermore, organic materials are flammable, and solvent vapors in the air can and do produce explosive mixtures. You should take some general precautions when doing organic chemistry: Do not get solutions on your skin. You do not need to always wear gloves...

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...

1. In a small beaker mix together 5.0 mL of 0.10 M Co(NO3)2 . 6H2O with 5.0 mL of concentrated HCl. Be sure to mix thoroughly with your glass stirring rod. This is your equilibrium mixture. 2. Place 1.0 mL of your equilibrium mixture in a small test tube add 1.0 mL of concentrated HCl. Observe any color changes and state in which direction (if any) the equilibrium shifted. Place a new 1.0 mL sample of your equilibrium mixture in...
