purges) summarises this point‚ saying‚ “People saw enemies everywhere‚ enemies who wanted to destroy the revolution and diminish the results of their hard work &accomplishments‚ and this only increased tension within society”. The purges deceived the general public and spread paranoia amongst the people‚ who thought the ideals of the revolution for which they had fought so hard‚ would collapse if they did not support Stalin. This directly resulted in the damage of morale and unity in the Soviet Society

The Generals In my personal opinion‚ I think that the Generals assemblage was a great success. Many websites and a book that I have looked at said that the statue gives off a humorous feel than serious. Most serious sculptures would only depict one rider on a steed‚ whereas the Generals has two men (one being our country’s Founding Father and the other Simón Bolívar‚ the political and military leader of Venezuela). It is also to be noted that the way the horse is depicted in the statue--it is very

Keghan Chapter 8 MULTIPLE CHOICE QUESTIONS Topic: Structure Elucidation 1. An alkene adds hydrogen in the presence of a catalyst to give 3‚4-dimethylhexane. Ozonolysis of the alkene followed by treatment with zinc and acetic acid gives a single organic product. The structure of the alkene is: CH3 A) CH3CH=C-CHCH2CH3 (cis or trans) CH3 CH3 B) CH3CH2C=CCH3 (cis or trans) CH2CH3 C) CH3 CH2=CCH2CHCH2CH3 CH3 CH2 D) CH3CH2CCHCH2CH3 CH3 CH3 E) CH3CH2CHCHCH=CH2

of the Upper Nepean Catchment. The following is a summary of factors that affect water quality. Water may contain several ions‚ namely anions and cations which are toxic to humans. Hardness is the scum on water surface from significant concentrations of calcium and magnesium ions. Total dissolved solids is the measure of dissolved solids that are ionic in water. Turbidity is the presence of suspended solids in water which reduces penetration of light‚ resulting in a decrease concentration of

Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a
