enthalpy lower than - 57 kJ/mol (numerically lower‚ not more negative!) Note that as the weak acid is in equilibrium as the hydrogen ions are ’mopped up’ by the base the equilibrium shifts to the right hand side to make more until eventually all of the acid is able to react. This does‚ however‚ absorb energy as bonds are being broken to dissociate the weak acid.

Biology coursework How does the temperature affect the rate of reaction? Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is

Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used

Introduction and Theory An investigative Cross-Country examination of the relationship between Commodities and Exchange Rates. The theoretical topic to be addressed will be to investigate the relationship between the fundamentals of exchange rates and commodities. In order to further current research‚ a variety of commodity and non- commodity currencies will be assessed. There will also be attempts to discern reasoning for the empirical results; relating to real life evidence such as compositions

Examine the main trends in the birth and death rates in the UK since 1900 As the population of a country increases‚ there will be certain factors affecting the people of that country; the birth rate‚ and the death rate are two of the major demographic trends. Since 1900 the UK has changed greatly‚ as has the demography of the country. The Birth rate - the number of live births per 1000 of the population per year originally was fairly high due to the fact that child labour was legal in Victorian

Is there any consistent relationship between levels of education and homicide rates? I did Japan and there was no relationship with education and crimes. b. Is there any consistent relationship between economic indicators and homicide rates? If so‚ which ones? They had a low homicide rates because of the high surveillance of the Japanese population.
