Description Whenever we do experiments‚ the actual result is a little different from the result we predicted. In chemistry‚ this discrepancy is compared by calculating the percent yield. In this lesson‚ we will define percent yield‚ and go over a few examples. !!!What is Percent Yield? Sometimes you look at a recipe and it says how many servings it will make if you follow the amounts listed on there. There are times‚ however‚ that the number of servings after you have made the food is not the

by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point‚ solubility‚ and conductivity‚ can be used to predict the type of bond that binds

a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead to stable molecules if they share electrons in such a way as to create a noble gas configuration for each atom. Hydrogen gas forms the simplest covalent bond in the diatomic hydrogen molecule. The halogens such as

the aims and key features of the Five-Year Plans change in the years 1928–41? The five year plans were introduced in 1928 by the Stalin and the USSR in order to industrialise Russia. Stalin wanted Russia to be self-sufficient which it wasn’t at the time to do this. The five year plans consisted of 3 plans were run from 1928-1941. The key features and aims of the five year plans can be viewed as being different for each one‚ however I will be arguing to a greater extent that the key aims and features

Homework #1 [Problem 4] Bond Price I discussed after class some ideas as to how to go about building the Bond Price function. This is problem 4 of the first homework assignment. There are three functions that have to be built. This is stated in the problem. The three functions are a function to calculate the present value interest factor for a single value. The second function returns a calculation of the present value interest factor of an annuity. The third function utilizes the first two

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic
