The Effect of the Concentration of Sulphuric Acid on the Reaction Rate with Magnesium Sarah Cain SCH 4UB Mr. Lankin April 1‚ 2009 Introduction The nature of the problem is to design an investigation that examines a variable affecting the reaction rate. In this experiment‚ magnesium will be reacted with different concentrations of sulphuric acid. The reaction is shown by the following chemical equation: H2SO4 (l) + Mg (s) → MgSO4 (aq) + H2

It is important to for me to have a good partnership with all parents and carers. Parents and primary carers are the most important people in every child’s life. These are the people who children will learn their values‚ culture and religious beliefs and they will the most influence on a child’s attitude and development. These are the people who a child feels the most secure with and who know the child best. In fact current legislation such as the Children Act 1989 gives parents and carers definite

Experiment 5 In the first part of this lab‚ the objective was to get the molar concentration of sodium hydroxide by using the secondary standard‚ sodium hydroxide solution with the primary standard‚ potassium hydrogen phthalate. With this information‚ we could create a second derivative plot‚ which can be used to obtain the exact concentration of the secondary standard‚ sodium hydroxide. Also‚ the indicator can give us these results along with the end points and with the readings from the pH meter;

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

bs-biology MW 1:00 - 2:30 & 3:00 – 6:00 A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They
