Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise

of the experimental values and theoretical values may have been to sources of error such‚ as weighing the flask before it has fully cooled down to room temperature‚ or allowing too much vapour to escape from the flask during heating. Each of these factors would result in a higher or lower molecular weight than the theoretical value.

Nowadays‚ the minimum wage legislation has been an increase in very many countries (Exclusivepapers‚ n.d.). According to Law Pay Commission (2006)‚ a minimum wage is the lowest wage that each employee can legally get from an employer in hourly‚ daily or monthly basis. This is the lowest amount at which workers can sell their labour. By each country independently having their laws‚ there has different opinions regarding the merits and the demerits of the minimum wage legislation. This essay will illustrate

United states should not pass a minimum wage. The reasons for this is that it will negatively impact the economy in several ways: Product costs will rise in order for companies to maintain profit margins‚ which will lead to drops in demand for products produced. This can ultimatley lead to job losses‚ as consumers may choose to purchase foreign goods which are more competetive in the market. Smaller companies will not be able to compete effectively in the market place‚ leading to more job losses

The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate of consumption of A = -[pic]rate of

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly
