The Programming Development Life Cycle (PDLC) Programming can be defined as the development of a solution to an identified problem‚ and the setting up of a related series of instructions which‚ when directed through the computer hardware‚ will produce the desired results. The notification that there is a problem can come from a systems analyst‚ an end user‚ or management. The problem needs to be defined so that the correct solution to solve it can be a program. Once a program is written‚ it is

Does Buying Local Organic Grown Foods Help the Environment? Buying locally grown organic foods helps us have a cleaner and healthier environment. Getting local organic foods rather than conventional foods reduces the carbon footprint that conventional foods bring about. This means that your food travels a lot less distance than other foods would. It has been said‚ that on average‚ a fresh food item travels about 1‚500 miles just to get to our plate. That is just one item; imagine how many miles

A cycle is a biological pathway or process in which the end product of one cycle becomes the starting point for the next cycles Write an essay about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration‚ the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration‚ the production

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

I feel that alcohol causes problems not only to the user/drinker but also to their spouses‚ children‚ and other family members. Problem drinking can change the roles played by family members in relation to one another and the relationships that surround them. As a family member develops this problem‚ the drinker may fail to perform his or her functions as a breadwinner‚ to the support their children or to complete chores. These things get done by another person‚ often times‚ the spouse. However

impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid. 3. What effects on the measured melting

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula
