this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the

Are people taking marriage less seriously as divorce rates rise? As divorce rates in the United States rise it seems that two groups of people are formed: one group deciding marriage isn’t for them and the other group being even more determined to make marriage work. A lot of factors can influence a person’s view on marriage. If a person has grown up with parents who never divorced and had a good marriage that might make them more determined to make their own marriage work. Those people

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

a stroke. In this‚ 610‚000 are first and new and 185‚000 are recurrent strokes. Nearly 75% of all strokes occur in people above the age of 65. The risk of having a stroke increases after the age of 55 but it can occur at any age. Stroke mortality rates are higher for African-Americans than for whites‚ even at younger ages (Mozaffarian et al.‚ 2015). The number of people living with stroke is expected to increase by 4 million by the year 2030 (Heidenreich et al.‚ 2011). Clinical types and subtypes

The problem of this article is that employee turnover continues to plague the leisure‚ tourism and hospitality industry as keeping and retaining employees become a huge issue. A common estimate is that employee turnover costs 1.5 times the departing employee’s income.

America’s Divorce Rates: Why Are They So High? The sanctity of marriage is a tradition that has been entered by generations over the past thousands of years. In the United States alone‚ 2‚200‚000 people choose to enter the lifetime commitment of marriage every year. Yet‚ less than half of that population is expected to keep that commitment. In a 1999 Rutgers University study‚ it is said that only 38 percent of Americans consider themselves happy in their married state‚ which has decreased from
