Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

HENRY WARD BEST KNOWN FOR Reverend Henry Ward is best known for changing the Jamaican school system. Up until Reverend Henry Ward got involved with the government to change it‚ the system was a flawed‚ failing system‚ with hundreds‚ if not thousands of children unable to get educated because of the lack of facilities. Although churches and infant centres tried their

Therefore‚ the importance of seeing environments beyond one’s own becomes even greater.

Activity 1.1.2 Investigating Basic Circuits (DLB) Introduction What is an electrical circuit? How can you manipulate components and design a circuit that will do what you want it to? This guided activity will introduce you to some components‚ tools‚ and concepts that are fundamental in electronics. It will allow you to investigate and discover: What are voltage‚ current‚ and resistance? How are they related to one another? What are some of the basic components that make up simple circuits and what

population distribution - defn. economic development S-N migration: Italy‚ 60million in population whereas the Mezzogiorno has 20million. mezzogiorno covers 40% of land and only 35% of the population. Change in population distribution - economic change. 1960’s S.Italy there was out-migration (population decline) towards NIP the North Italian Plain. 1951-1971: 4million people left southern Italy due to push and pull factors... PULL factor: Industrial Triangles in North attracted employment

Research Question: How will an increase of FeSO4 concentration affect the activity of the enzyme catalase? Hypothesis: By increasing the concentration of FeSO4‚ there will be a decrease in the activity of the enzyme catalase because the Iron (ii) in the metallic ion will act as an inhibitor during the catalysis of the hydrogen peroxide into O2 and H2O. Introduction: We rely on oxygen to provide us with energy (ATP) and go through all the phases of aerobic respiration. However‚ oxygen can be

The Digestive System Why is it that 1 in 3 people perhaps even more regularly battles some kind of digestion problems? Understanding how the digestive system works will help to understand why digestive problems are so common. The digestive system is more than stomach and intestines. It is a system of organs that turns food into energy and is one of the most important functions the body performs. There are many reasons that cause so many people to suffer with digestive problems. Three of

The Digestive System Structure and Functions Jermaine Kendrick Vista College The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are
