release approximately - 57 kJ/mol of energy on neutralisation with strong base. This energy release is due to the formation of water molecules from the H+ ions from the acid reacting with the OH- ions from the base. H+(aq) + OH-(aq) H2O(l) When a weak acid is neutralised some of the energy is needed to dissociate the molecules to make the hydrogen ions available for neutralisation. The result is a value for neutralisation enthalpy lower than - 57 kJ/mol (numerically lower‚ not more negative

Crime rate is basically defined as the number of Criminal Code offenses in an area reported to the police per 100‚000 population in that area (StatsCan‚ 2016). Crime rates provide an insight about the society and the deviance going in and around it. Crime rates steadily dropped in most countries in the 1990s but the most drastic change seen was in the North American region. According to Understanding why crime fell in the 1990s written by Steven D. Levitt‚ the homicide rates in The United States

Why is the Divorce Rate So High? Intro to Sociology April 25‚ 2006 A question that has been plaguing sociologists for years is the issue of high divorce rates.

found that the trial rate for “actual definitely would buy” for pizza will be 80% of the definitely would buy rate of the BASEL research. The actual probably would by is taken as 30% of the research’s probably would buy rate. After calculating the actual rates‚ we summed “definitely would buy” and “probably would buy” in order to calculate the trial rate‚ which is 27%. Before estimating the demand‚ we should calculate “marketing adjusted trial rate”. In order to calculate that rate‚ we took the average

Chemical reaction rate is the change in the concentration (per unit) of the reactants or products. Collision theory is our current understanding of how reactions can occur. The theory states that all reactants must collide with enough energy‚ the correct orientation‚ and with enough energy equal or greater than the activation energy to be successful. Reactions that don’t meet these requirements instead use an external factor to allow the reaction to occur. Some factors are high temperatures as it

Accounting rate of return The accounting rate of return (ARR) is a way of comparing the profits you expect to make from an investment to the amount you need to invest. The ARR is normally calculated as the average annual profit you expect over the life of an investment project‚ compared with the average amount of capital invested. For example‚ if a project requires an average investment of £100‚000 and is expected to produce an average annual profit of £15‚000‚ the ARR would be 15 per cent. The
