question. 1. Which type of compound usually has higher melting points‚ ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds usually have higher melting points. This is because the atoms of covalent compounds are bound strongly to each other in stable molecules‚ but those molecules are in general not very strongly attracted to other molecules in the compound. On the other hand‚ the atoms in ionic compounds show strong attractions

MODULE 5 SESSION LONG PROJECT Take the current amount you have in your checking or savings account. Suppose you have a choice of keeping your money for five years in a savings account with a 2% interest rate‚ or in a five year certificate of deposit with and interest rate of 4.5%. Calculate how much interest you would earn with each option over five years time with continuous compounding. I’m going to do this for my checking and savings account amount Checking Account A = Ce^RT My total money

What is Organic? The word ’Organic’ means ’living’‚ and in practical terms‚ this means natural food that is grown and processed without chemical fertilizers‚ pesticides‚ herbicides or fungicides. Nothing unnatural is allowed so there are no growth hormones‚ antibiotics‚ preservatives‚ dyes‚ chemical coatings or irradiation allowed. There is no genetic engineering allowed in organic foods. Organic food is nothing else but good pure nutritional food - the way it used to be. Toxic overload

Organic Food vs Non Organic Food In today’s society you walk into a grocery store and you always have the option of organic or non organic food. There are even grocery stores dedicated to organic foods like Trader Joe’s‚ Sprouts and Whole Food market. I personally have gone organic and will never go back to eating or drinking non organic food. Organic food may be pricey but less hormones‚ less cow puss and blood in your milk‚ and less pesticides. The controversies about organic food vs non organic

Chemistry revision Atoms elements and compounds Atom-the smallest part of an element that can still be recognized as an element Element-a substance made up of only one type of atom. An element cannot be broken down chemically into any simpler substance Nucleus-middle of the atom‚ which contains protons and neutrons Electron-tiny particle‚ which surrounds the nucleus with a negative charge Compound-when two elements react and combine together which contain more than one element.

- Dropper - Timer Procedure: 1. Set up a row of eight test tubes. Use a marker to number them 1 through 8. 2. To each test tube‚ add 4 mL of the solutions listed above‚ matching each number to the number on the tube. 3. Add one dropperful (2mL) of Benedict’s reagent to each tube. 4. Mix the reagent and the sample by agitating the solution in each tube from side to side. Record the original color of each tube’s contents in your data table. 5. Heat the test

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Being able to extract a compound or substance from a product or object will encourage us in being able to do the same in a similar manner with a tea solution. Extracting compounds is an important step in any kind of organic chemistry lab and will help us be better at accomplishing the experiment in a much faster and accurate rate than from before. Experimental To begin the experiment‚ a tea solution must be made by incorporating a tea bag into a beaker filled with almost boiling water and the
