article: When the baking soda combines with liquid and acid, it creates carbon dioxide bubbles that will help breads, cookies, and other baked goods to expand. You can add baking soda to any recipe that contains a liquid (such as water or milk) and an acid, such as:  Lemon juice Cream of tartar Sour cream Buttermilk Vinegar The alkaline nature of baking soda will cut the acidity in foods that have too much. For instance, if you're making tomato soup or sauce and find that it’s too acidic, stir in 1 teaspoon (5 g) of baking soda to neutralize the flavor. You can also add baking soda to lemonades, store-bought soups and sauces, canned tomatoes, and even tea to cut the acidity and bitterness. You can make your own baking powder by combining 2 teaspoons (7 g) of cream of tartar with 1 teaspoon (5 g) of baking soda. Whisk the powders together thoroughly to produce 1 tablespoon (14 g) of baking powder. Use equal parts homemade baking powder as a substitute for the store-bought version. Wet your produce with a small amount of water and sprinkle baking soda over the skin. Scrub the fruit or vegetable with a damp cloth to remove dirt and residue. Rinse the fruit or vegetable with fresh water before eating or preparing.

article: Some medications can increase your risk of bruising after surgery, such as heart medications and blood thinners. For instance, aspirin, clopidogrel, and warfarin can all increase your chance of bruising. As most of these medications are necessary to keep you healthy, it's not recommended that you stop them, although, you may be able to stop aspirin for a week before your surgery under a doctor's orders and supervision.  Other medications that can lead to this problem include dabigatran, enoxaparin, ticlopidine, and dipyridamole.  Have your doctor review your medications to help you determine which ones may lead to more bruising, and when they should be stopped before the surgery and restarted after the operation. Depending on the indication, some of these medications cannot be stopped and will need to be continued throughout the surgical period. Herbal supplements can also lead to an increased risk for bruising. For instance, if you take garlic or ginkgo biloba in pill form, it can increase your chances of bruising. Vitamin E can also have this effect. As these pills are not medically necessary, you may be able to stop them before your surgery; usually, you can take a break from them starting 2 weeks before your surgery. How you are positioned during surgery can affect how much you bruise. Having an open discussion about your concerns before surgery may encourage your doctor to make changes if necessary.  For instance, if you are having surgery on your face, your surgery should be conducted with you in a chair with your head on a headrest. In addition, the angle of the chair should be angled back about 30 degrees from straight upright.  The room should be bright enough to look for blood vessels, and a side light is especially helpful. One way you can help your doctor is by removing all traces of makeup before entering the clinic; it's best not to put any on the morning of your surgery. Makeup can hide your blood vessels. If your doctor nicks a blood vessel, it can lead to more extensive bruising. You can also ask what your doctor uses to look for blood vessels to help reassure you. Some use magnifying glasses, while others use more advanced technology, such as devices that use infrared technology to help your doctor look for blood vessels. The night before your surgery and the night of your surgery, it's best to skip the alcohol. Alcohol can make bruising worse. While studies aren't conclusive about this natural remedy, some people have had luck with it reducing bruising. Make sure your doctor knows you plan to take it around your surgery time, though, because like any medication, it can react with other medications.  Bromelain is an enzyme found in pineapples. You can find it in natural health stores in capsule form. Try 500 milligrams four times a day for a day or two before your surgery and a few days after. Be sure to ask your doctor if this dosage is safe for you. Use quercetin along with the bromelain. This is a plant flavonoid that can be found in capers, apples, red onion, citrus fruit, and leafy green vegetables, or in the form of a supplement. Take this with the bromelain to help reduce swelling and bruising.

article:
Atomic mass, the mass of a given atom or molecule, can be expressed in standard SI mass units - grams, kilograms, etc. However, because atomic masses, when expressed in these terms, are incredibly small, atomic mass is often expressed in unified atomic mass units (usually shortened to "u" or "amu") or in Dalton's (Da). The standard for one atomic mass unit is equal to 1/12th of the mass of a standard carbon-12 isotope. Atomic mass units tell the mass of one mole of a given element or molecule in grams. This is a very useful property when it comes to practical calculations, as it allows easy conversion between the mass and moles of a given quantity of atoms or molecules of the same type. Most standard periodic tables list the relative atomic masses (atomic weights) of each element. This is almost always written as a number at the bottom of the element's square on the table, under its one or two letter chemical symbol. This number is usually expressed as a decimal rather than as a whole number.   Note that the relative atomic masses listed on the periodic table are average values for the associated element. Chemical elements have different isotopes - chemical forms that differ in mass because of the addition or subtraction of one or more neutrons to the atom's nucleus. Thus, the relative atomic mass listed on the periodic table is suitable as an average value for atoms of a certain element, but not as the mass of a single atom of that element. Relative atomic masses, as listed on the periodic table, are used to calculate molar masses for atoms and molecules. Atomic masses, when expressed in amu, as on the periodic table, are technically unitless. However, by simply multiplying an atomic mass by 1 g/mol, a workable quantity is obtained for an element's molar mass - the mass (in grams) of one mole of an element's atoms. For example, the atomic mass of iron is 55.847 amu, which means one mole of iron atoms would weigh 55.847 grams. As has been noted, the relative atomic masses listed for each element on the periodic table are average values of all of an atom's isotopes. This average value is valuable for many practical calculations - like, for instance, calculating the molar mass of a molecule comprised of several atoms. However, when dealing with individual atoms, this number is sometimes insufficient.   Because it's an average of several different types of isotopes, the value on the periodic table isn't the exact value for any single atom's atomic mass. The atomic masses for individual atoms must be calculated by taking into account the exact number of protons and neutrons in a single atom.
