Are your feet‚ legs‚ ankles‚ or hands swollen? This condition is called edema‚ commonly known as water retention‚ and is manifested by buildup of fluids in the cavities‚ circulatory system‚ and the tissues. In most cases‚ edema is caused by pregnancy‚ menopause‚ burns‚ contraceptive pills and any other pill containing estrogen‚ medications like vasodilators and NSAIDs‚ physical inactivity‚ and poor diet. The symptoms of edema depend on the root cause and they typically develop slowly over time

stomach acid. They are used to relieve acid indigestion‚ upset stomach‚ sour stomach‚ and heartburn. Antacids are taken by mouth and work by neutralizing excess stomach acid. They contain ingredients such as aluminum hydroxide‚ calcium carbonate‚ magnesium hydroxide‚ and sodium bicarbonate‚ alone or in various combinations. Antacid products may also contain other ingredients such as simethicone‚ which relieves gas. Antacids differ in how quickly they work and how long they

ABSTRACT The effect of inorganic cofactor such as Magnesium to the rate of respiration of yeast was determined using Durham tube assembly with the substrate glucose. After thirty minutes‚ the test tube with the cofactor in the form of Magnesium sulphate MgSO4 showed the higher amount of carbon dioxide evolved which was measurable through volume and was one of the by- products of cellular respiration. This stated that the higher amount of CO2 evolved‚ the higher the rate of respiration. Thus‚ the

now has eight electrons that fill the 2s and three 2p orbitals. Magnesium (group 2A) has 12 protons and 12 electrons in the neutral atom. This gives magnesium two more electrons than neon‚ the noble gas closest to it in the periodic table. In losing two electrons‚ magnesium forms a cation with a+2 charge‚ which still has 12 protons‚ but now has only 10 electrons in its electron cloud. In terms of valence electrons‚ a neutral magnesium atom‚ with an electronic configuration of 1s22s22p63s2‚ has two

Introduction a. Magnesium is a very active metal which can reduce copper (II) ions in a weight sample of a compound to metallic copper. The reduction of copper ions in a compound to a copper metal is caused by the addition and oxidation of magnesium. The reaction takes place in an aqueous solution of a weighed sample of a copper-containing salt. Magnesium completely displaces copper from the solution allowing for measurements. Hydrochloric acid is then added to dissolve the excess magnesium which also

also poses a huge threat to our vegetation as well. When salt dissolves in water‚ it replaces important nutrients that all plants need to survive. The sodium ions separate from the chloride ions and the nutrients such as potassium‚ calcium‚ and magnesium‚ nutrients that the plants need to survive‚ are replaced by the salt ions. When this happens‚ it can disturb the photosynthesis of the plant‚ or cause the plants to become stressed out. If plants continue to not receive nutrients‚ and continue to
