The Effects of the Western Fast Food Diet In recent decades there has been a change in the global food and nutritional profile‚ where "left the scene" the traditional food‚ and fast foods came on to the scene. With the convenience of today’s world and with all the technological advances‚ people are induced to sedentary conditions‚ thus leaving to conduct physical activity and lose weight.

From the experiment‚ it was determined that Sodium chloride had a crystalline structure‚ even after being broken into smaller pieces with a hammer. Even though there was two different types of Sodium chloride‚ coarse and fine‚ they still had a symmetrical‚ three-dimensional shape. All ionic compounds have this structure. It was also found that Sodium chloride had a high melting point and sugar had a low melting point. This is because Sodium chloride is ionic and the bonds holding it together take

I. Introduction The purpose of this experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble

CAUSES AND EFFECTS OF THE POPULARITY OF FAST FOOD Nowadays‚ most people -especially kids and young people- prefer to eat fast food‚ such as hamburgers‚ pizza‚ fried food‚ etc. Why it has become so popular? It tastes better than homemade food? We do not believe it is only the taste the reason of the popularity of fast food. There are several reasons why fast food had become popular over the years. It is popular because it is cheap‚ quick and convenient to those who have

The moles of sodium thiosulphate can be determined using the average titre values and its concentration. When calculating the average titre values‚ the outliers are ignored because they are mainly created by errors and their great difference from the titres achieved in other trials will pose a great impact to the accuracy of the final result. n=v × c Where ‘n’ is the moles of sodium thiosulphate‚ ‘v’ is the average tire values sodium thiosulphate‚ and ‘c’ is its concentration

Background An indicator is a halochromic chemical compound that is added to a solution to determine its pH. It is a chemical detector for hydronium ions. The indicator changes colour to show the pH of the solution. Some indicates are not very precise and only tell us whether the solution is acidic or basic. When the indicator is added to the solution‚ they bind to hydrogen or hydroxide ions. The different electron configurations of the bound indicator cause the indicator ’s colour to change.

To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a greater number of

Leticia Jackson The Causes and Effects of Fast Food Consumption Often times many wonder what drives an individual to eat fast food. Thinking about the numerous amount of calories sin each fast food meal one would choose not to eat such a thing. There have been studies that have shown that the amount of fast food consumption has grown tremendously in the last couple of years. There are many causes of people eating such foods; such as‚ lack of knowledge on what people are consuming‚ lacks of

social and habitual life. Every year we read sad stories of how animals have been treated badly even resulting in their death in some cases. Another sad situation is the long-haul transport of animals even between countries. The killing of animals for food is almost unnecessary today in terms of human nutrition. From a nutritional point of view‚ vegetable proteins - particularly legume proteins - are as good as animal proteins if composed in correct proportions. Only pregnant and ovulating women occasionally
