During dilution process, what do you do if you add a bit too much solvent when filling the volumetric flask to the mark? O Calculate the equivalent amount of salt and add that to the solution O Remove the excess content of the flask until the volume matches the calibration mark O Start over, the solution cannot be saved OUse a distillation unit to evaporate the excess solvent

Below are described three methods through which breads are leavened (risen). Which of them are chemical changes? 1. Yeast breads: Yeast added to flour and water digests carbohydrates from the flour and produces carbon dioxide (CO2) which forms bubbles in the flour water mixture. 2. Quick Breads: Flour, water, baking soda (NaHCO3) and a source of acid, are mixed and baked. The baking soda interacts with acids and heat in the batter to release carbon dioxide (CO2) gas, forming bubbles in the mixture. 3. Flat Breads: A mixture of flour and water are exposed to high heat, causing the water to evaporate quickly, forming bubbles in the mixture.   A)yeast breads B)quick breads C)flat breads D)yeast breads and quick breads E)quick breads and flat breads

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Part IV Cabbage Juice Indicator Chop cabbage into small pieces until you have about 2 cups of chopped cabbage. Boil for at least ten minutes to allow time for the color to leach out of the cabbage. Allow it to cool for 15 min • Filter out the plant material to obtain a red-purple-bluish colored liquid. 1. Add 1-2 drops of cabbage juice into a small bowl 2. Add 3-5 drops of vinegar into the bowl with the cabbage juice 3. Observe Is this a chemical change or physical change? Explain? Store the excess cabbage juice in your refrigerator, you will need them for future experiments.

A farmer is considering planting maize, wheat or ryegrass in a 30 hectare field. Table 1 gives values for the amount of Nitrogen (N) and phosphorus (P) removed from the soil by maize, wheat or ryegrass. Table 2 shows the balance between the inputs and the outputs of phosphorus within the 30 hectare field. 1.) Using the tables, calculate the next soil phosphorus balance if: a. Wheat was planted b. Maize was planted c. Ryegrass was planted 2.) identify the crop which produces the greatest phosphorus stress within the soil. 3.) suggest what steps the farmer may take to avoid phosphorus loss within the soil.
