How can we contribute towards our society in the smallest possible way? We are apes‚copycatsof west in Culture‚Fashion‚Independence‚Freedom.We as individuals need to understand our responsibility.Our youths have loved their dresses‚became party animals‚night owls have engaged live-in relationships.Teenagers can be seen flaunting in front of their comrades. But friends i would like to raise a question ain’t we trampling our freedom?Are we really behaving as human beings and not opportunist animals

Sodium‚ one of many elements in the periodic table is being used in everyday life‚ it is also an essential element within your body. It is just another element‚ but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine‚ industry‚ and agriculture(Shriver). Sodium was discovered in 1807 by a man named Sir Humphrey Davy. He was well known for his discoveries of most alkali metals

The different types of diets Glucose Control - Diabetic Diet Nutrition experts say that there is no one diet for diabetes‚ but people with diabetes should follow the nutrition guidelines in the Food Pyramid‚ while paying special attention to carbohydrate intake. People with diabetes should also eat about the same amount of food at the same time each * Eat more starches such as bread‚ cereal‚ and starchy vegetables. Aim for six servings a day or more. For example‚ have cold cereal with nonfat

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

Purpose: The Purpose of this lab is to utilize‚ demonstrate and understand the various techniques and procedures used to gravimetric labs. For this particular lab we will utilize our scientific knowledge of related to gravimetric procedures to find the chloride content in an unknown soluble salt. Theory: Using our developed knowledge of the conservation of mass‚ solubility and precipitation it is possible (with some degree of error) to know the content of chlorine in a particular salt by dissolving it

12-STANDARDIZATION OF SODIUM HYDROXIDE Standard solutions for titrations are especially pure mixtures with exactly known concentrations. Primary standards are very pure solids. They have the advantage that they can be weighed (the analytical balance is normally the most accurate instrument in the laboratory) and they are stable under laboratory conditions. In this experiment‚ the primary standard is oxalic acid dihydrate‚ H2C2O4 ( 2H2O. It will be used to standardize a solution of sodium hydroxide

Decomposition of Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate?
