Sulphuric acid
there are many types of acids, ask a question on what kind of acid you want to make.
Acid rain is created when pollutants such as sulfur dioxide and nitrogen oxides combine with water vapor in the atmosphere to form sulfuric acid and nitric acid. These acids are responsible for the acidity of rainwater.
Choose an acid and then add acid to water (and NEVER add water to acid). The amount of water, depends on the exact concentration of the dilute acid needed. The molecular formula of the acid will not vary after dilution, just its concentration will reduce.
To make a 9N (normal) Phosphoric Acid solution, you will need to know the concentration of your Phosphoric Acid. The formula to calculate the volume of Phosphoric Acid required is: Volume (in liters) = (Desired Normality * Equivalent Weight of Phosphoric Acid * Volume of Solution) / Concentration of Phosphoric Acid.

Currently, skinny, distressed, acid-washed, and, bootcut jeans are in style. However, make sure that your outfits go together--- Chic skinny jeans should not be worn with a baggy tee shirt and a pair of beat up sneakers. Think carefully of what matches AND what looks good on you. If you are still having trouble, pick up a fashion magazine (i.e. TeenVogue, Elle) and look at the pictures and articles. It also depends on you shape: For example, if you are short, try long, lean styles. This will lengthen your body. Also, if you are good in heels, try to get jeans long enough to cover a pair. Dark shoes with dark jeans lengthen your body, as well as high waisted-pants that will make your legs look that much longer. Wear what makes you feel comfortable, too! If you aren't comfortable wearing acid-washed jeans, don't wear them.
