Title: Formula of a Hydrate. Objective: Determining the percentage of water and the chemical formula of a hydrate. Background: Water has a polar structure and it has positively and negatively charged parts within each molecule. This gives it a strong attraction toward ions. The ions in some salts attract and form strong bonds with water molecules. These salts‚ when they have absorbed water‚ are called hydrates. Anhydrous salts are salts that can form hydrates but which have had all the water

Six-Gun Mystique. His description of the Western formula being “far easier to define than that of the detective story” may clearly be a paradigm for many authors‚ but not particularly for Stephen Crane. The standards Cawelti has set forth for a successful Western is quite minimal by thought‚ but at the same time relevant. Crane signifies a different perspective to these standards. Crane’s thoughts for the use of the Western formula are just approaches towards the west‚ from the

Slovin’s Formula Sampling Techniques * By Steph Ellen‚ eHow Contributor * When it is not possible to study an entire population (such as the population of the United States)‚ a smaller sample is taken using a random sampling technique. Slovin’s formula allows a researcher to sample the population with a desired degree of accuracy. It gives the researcher an idea of how large his sample size needs to be to ensure a reasonable accuracy of results. * When to Use Slovin’s Formula * If

Return on Shareholders Funds (ROSF) Ratio Definition: The Return On Shareholders Funds (ROSF) ratio is a measure of the profit for the period which is available to the ordinary shareholders with the ordinary shareholders’ stake in a business. Formula: Return On Shareholders Funds = ((Net profit after taxation & preference dividend) / (Ordinary share capital + Reserves)) * 100% Example 1: If the net income of PPC Ltd is $80‚000 whereas shareholder’s funds are $500‚000. Then‚ the ROSF =

A Formula for Happiness Bishop Gary E. Stevenson A formula embodied in the gospel of Jesus Christ reveals the pathway to happiness. It is a plain and precious truth found throughout the Book of Mormon. It is described particularly well in the teachings of the prophet Lehi to his sons as he neared the end of his life. In speaking to his son Jacob‚ he taught‚ “For it must needs be‚ that there is an opposition in all things” (2 Nephi 2:11). A few verses later he added‚ “Men are‚ that they might
