How does Wilfred Owen represent conflict in Dulce ET Decorum Est? Refer to other poems in your answer. The entire story of Dulce et Decorum revolves around conflict. It was the first poem to show a realistic description of the war. It was conflict that created the atrocity that we call ‘The Great War’. This is showing one of the many devices Wilfred Owen and Siegfried Sassoon used in their famous War poems and the conflict that ended the lifestyles that they describe. Wilfred Owen and Siegfried

DryLab - III 1. What experimental evidence leads scientist to believe that only quantized electron energy states exist in atoms Answer The evidence was the Niels Bohr experiment on Hydrogen gas that established a quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. 2. a. what is the wavelength ranges of the visible spectrum for electromagnetic radiation Answer The ranges of visible spectrum for human eye is between 390 to 700nm

Rules for aromaticity 1. A cyclic planer structure and each atom must have a P orbital so that the electron cloud is not intterupted 2. It must contain an odd number of electron pairs ▪ i.e. the number of electrons must be 4n+2 where n=0‚1‚2‚3‚4……… ▪ so the number of electrons is 2‚6‚10‚14‚18……. ▪ this rule is called the Hückel’s Rule • monocyclic hydrocarbons with alternating single and double bonds are called annulenes • annulenes are named as [n]-annulene

Outline some of the major changes that have taken place in family life since the 1970s and discuss the concerns arising from these changes. In the past many families were similar‚ as traditional nuclear families were the excepted norm of society. Since the 1970’s a number of major changes have taken place in family life. The traditional nuclear family is no longer seen as the norm as many other types of specialist families have developed to best suit the needs of the people within them. Family life

for the nuclear family to no longer be the norm‚ for example‚ one in ten households are headed by a lone parent‚ which is due to death or divorce after having children. The rise in divorce creates a rise in lone parent families. Lone parent families are most common in the working class rather than middle and upper class. Nearly 50% of Afro-Caribbean families are lone parent families. As well as lone parent families‚ reconstituted families have also risen due to divorce. A reconstituted family is where

He risked his life to talk to Ten Bears‚ even something Lone Watie did not think that Josey would come back alive from. Laura Lee was an especially important part of Josey’s new family. Her gift of a watch band made out of her own hair brought Josey back into time. She served as a goddess to Josey‚ and helped

Topic 5 – Bonding and Structure Revision Notes 1) Introduction • Atoms form bonds to get a full outer shell of electrons • There are three types of bonding: ionic‚ covalent and metallic • The structures produced by forming bonds are either giant or simple • The possible combinations of structure and bonding are giant ionic‚ simple covalent‚ giant covalent and giant metallic • Simple covalent is sometimes called simple molecular • Giant covalent is sometimes called giant
