Q: Regular usage of hard water can lead to dry, irritated skin. Combat this effect right after showering, bathing, or washing your face by moisturizing right away. Use a facial moisturizer and rich body lotion, and apply generously.  A non-alcohol toner can also be used after washing to remove traces of minerals and heavy metals. Warm coconut oil can also be used as an intensive body moisturizer. Hard water may leave mineral deposits in your hair and on your scalp, leaving it dry. Counteract this effect by purchasing a chelating shampoo, which contains an ingredient that bonds with the minerals in hard water and helps to rinse them away. Look for a shampoo (in pharmacies, beauty supply stores, or online) that contain “EDTA”, or Ethylene Diamine Tetra Acetate. Consider switching to a sulfate-free shampoo or cleanser as well. Sulfates can react with metals and minerals found in hard water. Hard water makes it difficult for soap to dissolve, leaving a buildup on your skin that can have negative effects (e.g. dryness, irritation). Using less soap can lessen this effect simply by cutting down the amount of potential buildup. When washing, focus larger amounts of soap on areas where you perspire frequently (like your underarms) and use it sparingly on the rest of your body.
A: Moisturize skin after washing. Use a chelating shampoo. Use less soap.

Article: Make up three to four concentrations of one solution. Using a spectrophotometer, measure the absorbance of one concentration of solution at a given wavelength. Start with the lowest concentration of solution and move to the highest. The order isn’t important, but keep track of which absorbance goes with which calculation. Using the values obtained from the spectrophotometer, plot each point on a line graph. For each individual value, plot the concentration on the X-axis and absorbance on the Y-axis. Draw a line between each of the points. If the measurements are correct, the points should form a straight line indicating absorbance and concentration are proportional to Beer’s Law. To calculate the slope of the line you take rise divided by run. Using two of your data points, subtract the X- and Y-values from each other, then divide Y/X.  The equation for the slope of a line is (Y2 - Y1)/(X2 - X1). The point higher on the line is given the subscript 2, while the lower point is given the subscript 1. For example: The absorbance at a .2 molar concentration is 0.27 and at 0.3 molar is 0.41. The absorbance values are Y-values, while concentrations are X-values. Using the equation for a line (Y2 - Y1)/(X2 - X1) = (0.41-0.27)/(0.3-0.2) = 0.14/0.1 = 1.4 is the slope of the line. The final step to calculating molar absorptivity with data points is to divide by the path length. The path length is the depth of the cuvette used in the spectrophotometer. Continuing our example: If 1.4 is the slope of the line and the path length is 0.5 cm, then the molar absorptivity is 1.4/0.5 = 2.8 L mol-1 cm-1.
Question: What is a summary of what this article is about?
Measure the intensity of transmitted light through varying concentrations of solution. Plot the concentration versus absorbance on a graph. Determine the slope of the line-of-best-fit through the data points. Divide the slope of the line by the path length (depth of the cuvette) to calculate molar absorptivity.

Q: Credit unions are small, local banks that are owned by members rather than shareholders.  Because of this business model, credit unions tend to have lower fees and a different customer service model that evaluates loan applications based on more than just a credit score. If your credit is poor, the rate will still be high, but not as high as it would likely be at a large bank. Because credit unions are member-owned, you must become a member and be eligible for a loan. Opening an account at a credit union is the same as opening an account at any bank. Bring some cash and identification and a banker will help you set up a checking and/or savings account. Talk with a banker at the credit union about your eligibility for a loan, and fill out the necessary paperwork.  Because of the more personal approach taken by credit unions, the banker you talk to will be more likely to take into consideration your individual circumstances when applying for a loan. Even if a large bank has denied your loan application, a credit union may approve it.  Nonetheless, you should not expect to receive a loan under the same terms and conditions as you would if your credit was good: bad credit will still mean that any funds you receive will only be granted at a high interest rate. This is because the bank is taking a greater risk on your loan than on a loan to someone with a better credit score.  Your specific rate in this case can vary based on the loan offer your credit union makes. Consult an online loan repayment calculator to determine your payments and repayment schedule.
