Gcse chemistry coursework magnesium oxide

If magnesium ribbon is replaced with an equivalent weight of powered magnesium, does the rate of reaction between magnesium and hydrochloric acid double? I would also consider using a wider range of concentrations so I can do in-depth analysis and I can compare the two acids.

Calculate the relative atomic mass of Chlorine. This shows what might be taking place at a sub-microscopic level. Background Research Chemical reactions are to do with changing the materials that form the base of your experiment. Burning and explosions are very fast reactions: Energy profile of an unsuccessful reaction Here, the reactants do not have sufficient energy to react so the activation energy is not achieved, successful collisions do not occur and no products are formed.

Chemical formula of potasium sulphate. The hydrogen bond is mainly defined as a strong electrostatic dipole-dipole interaction. Click on the arrow to follow the method used. The electrons within the atoms move around but move in sync with each other to preserve the attractive force mtchemers, The outer shell in oxygen atom needs to gain more electrons to enable it to reach a stable state by achieving its nearest noble gas configuration 2.

I could have use a colorimeter to identify colour changes in the products. I tied my hair back, tucked in my tie and pushed all stools and bags under the desk where there is no risk of anyone tripping.

I did, however find some outliers in my results.

Chemistry Questionnaire

The dissociation reactions and Ka values of carbonic acid are given below. Reactions that occur slowly have a low rate of reaction. Potasium has 1 projection since it has a valency of 1 and Sulphate has 2 grooves representing a valency of 2.

Decide never to repeat experiment. All you can do, unless you can arrange a pretty good vacuum around it, is to wait for it to lose interest. List of factors that can be used to control the rate of a reaction The rate of a reaction can be increased by: However, strong alkalis are not to be recommended as a suitable medication for 'heartburn' afflictions, since they can be just as irritating as strong acids!

Here are some facts about perfumes. Not unless you want it a very big bulk magnesium fire. Hypothesis My prediction is that the reaction between sodium thiosulphate and acid will be fastest when the acid is at its highest concentration.

SweatBasically, the holes in the material are too small for water drops to pass through but big enough for sweat vapour. Rates of ReactionThis site uses cookies from google and other third parties to deliver its services, to personalise adverts and to analyse traffic. The equally strong alkali potassium hydroxide KOH is used in alkaline batteries.

This shows that there is a difference in the data which proves accuracy. Study Variables The Dependent Variables: In the periodic table each of the rows is called a period. The mass number is placed as a left superscript of the symbol.

There are three types of intermolecular interactions, which are Hydrogen bonding, vander Waals and Dipole-Dipole Clarkson, Equipment and Materials The following chemicals and reagents were required in the experimentation: Chemical formula is a short notation of writing names of compounds.

Who can help me? This is because the first energy level can hold a maximum of two electrons.

Study Guides

Hydrogen atoms can each form one covalent bond, while oxygen atoms can each form two covalent bonds. For example, if a car travels at 50 km h-1, it is simply stating that in 1 hour, a distance of 50 km is travelled.

Taylor Varga [Worm, Luna Varga]

Understanding what chemical change is As David Read explainsthe challenge for many students is switching between macroscopic, sub-microscopic and symbolic representations.[4] (c) Describe two differences in physical properties between transition metals and a s-block metal such as magnesium, suggesting reasons for these differences based on their atomic structures.

[3] 11 (d) The oxidation of manganese(IV) oxide in alkaline solution in air produces green manganate(VI) ion, MnO Chemistry Project and Experiment Ideas. Unleash your inner mad scientist.

The rate of reaction between magnesium and hydrochloric acid increases as you increase the surface area of the magnesium. For example: powdered metal (greater surface area) reacts quicker with acid than strips of metal (lower surface area).

Magnesium + hydrochloric €magnesium + hydrogen solution and manganese oxide. €€€€€€€€€ Draw, on the axes above, a graph to show the result you would expect if the volume of hydrogen peroxide solution had been the same, but it was twice as concentrated.

Chemistry coursework rate reaction hydrochloric acid magnesium. The rate of reaction of magnesium with hydrochloric acid- Learn - investigating the effect of varying concentration on the reaction between magnesium ribbon and hydrochloric acid aim it is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid.
