Indicators can be used to determine whether these substances are acidic‚ basic or neutral. Manufactured indicators are one type and the second type is natural indicators. Believe it or not‚ the majority of fruits‚ vegetables and flowers contain pigments which may be used as acid-base indicators. For example‚ Red cabbage contains within its

I base my values on stuff that makes me happy. My God is the head of my value system. I believe spiritual growth is the foundation of my life and everything else will follow suit. One major value in life is peace of mind that is something I treasure. Being able to sleep at night‚ without anxiety‚ fear or anything affecting my ability to sleep. Knowing that I have God to watch over me‚ taking all the problems and issues away makes me value him so much more. When my mind is at peace I can get through

Put simply‚ The Different Kinds of Monsters by Seth Chambers is a story clearly meant to expose readers to the different forms of monstrosity that have always existed in our world‚ beginning in the era of the dinosaurs and ending (at least in terms of this novel) with the current state of humanity. On the surface‚ this novel merely tells the story of the Armitage family and their relationship to a prehistoric dinosaur‚ Emily (or “First‚” if you prefer). The story is told both from the point of view

The Different Kinds of Monsters written by Seth Chambers follows a story of a young man named Dylan Armitage‚ traveling around the United States throughout his life as he meets new people along the way‚ seeing the different sides of them and their monsters‚ including his. The title itself is pretty self-explanatory – that there are different kinds of monsters in this world. But what’s not self-explanatory is that there are monsters‚ outside and inside of us. Just as there was a famous saying that

RESOURCES BASE VIEW Financial resources: The 1998 financial report shows that SingTel‚ the largest telecommunications company in Singapore‚ has a huge reserve (cash and bank deposits) of S$4.44 billion. This is the company’s strength as not many companies have such large reserves. The debt-to-equity ratio1 in the last 3 years was also very low. In fact in 1997‚ it was just 0.05 as opposed to in 1998 and 1999 when it was merely 0.06. With such a huge reserve and low debt-to-equity ratio‚ SingTel

Objectives 1. To separate a mixture of an acid and a neutral compound into its component by extraction. 2. To determine the melting point and the yield of the benzoic acid and the unknown sample. 3. To determine the unknown sample whether is is Trimethylmethanol or 1‚2‚4‚5-Tetrachlorobenzene. Introduction Extraction is a process of transferring a solute from one solvent to another. It is usually used to separate one or more components from a mixture. Diethyl ether‚ dichloromethane

Introduction to Acids Base chemistry Purpose How to determine the constant equilibrium of an acid‚ Ka? How to evaluate the concentration (M) of an acid? In “part A” experiment‚ we would test the PH of different concentration of acetic acid (a weak acid which partially dissociated in water) with a PH probe. After we got the PH‚ we could find out the concentration of H+ by applying the relationship pH = -log [H+]. Having the determined value of [H+] of a weak acid with a known molar concentration
