Reaction Between Hydrochloric Acid and Magnesium Essay

Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas. One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction. CaCO + 2HCl CaCl + H O + CO = = =

Please Note: This lab involves a lot of waiting for the gas collection. Make sure you allot yourself the full three hours to perform the experiments.

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:

Because it is dangerous to burn magnesium, it is not possible to directly record heat change. Our lab team suggests an indirect way of determining the heat of combustion for magnesium. To accomplish this, we need to perform two separate trials. One uses a solid (powder) version of MgO, while the other uses Mg ribbon. With the results from these, we can use Hess’ Law to determine q=∆H. This provides both a safe and successful way of indirectly determining the heat of combustion for magnesium.

It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid.

1. Gather appropriate lab equipment and secure a safe workspace with open ventilation, away from children and pets. All chemicals will be combined in the 96 well plate. Don’t contaminate end of pipet with other chemicals.

Both experiments were able to determine the yield of hydrogen gas by testing the effect of limiting reactants, balanced equations, stoichiometry, mole ratios and molar masses. Balanced equations are equations that have a balanced number of moles of each element on both sides of the equation. Molar mass is the sum of the atomic masses of all elements combined in a chemical substance. Mole rations can be determined using the coefficients of the reactants and products in the balanced equation. Mole ratios can be used to relate moles of product formed from a certain number of moles of a reactant. Stoichiometry is the method of using the relationship between two or more substances in a chemical reaction. The limiting reactant of a chemical reaction is the reactant that is used up first in the reaction and limits how much of the product can be formed. In experiment 2-1, a company wanted to know if magnesium or aluminum would be practical to use as an alternative to zinc to produce a given volume of hydrogen gas. In experiment 2-2, the company wants to know how to optimize the production of hydrogen gas and whether hydrochloric or sulfuric acids are reasonable alternatives for gas production. The The reactions performed in experiment 2-1

The purpose of this experiment is to verify the formula of magnesium oxide based on the masses of magnesium and the product (MgO). We verify the formula firstly by calculating the empirical formula of magnesium oxide and then calculating creating the magnesium oxide itself- a magnesium ribbon is combined with oxygen in the presence of air through combustion and this forms MgO. The empirical formula of a compound is the simplest method of expressing a chemical formula in whole-number ratios of the constituent atoms that are consistent with masses measured in the experiment; whereas the molecular formula expresses the chemical formula using the actual number of atoms. For example, the molecular formula of anthracene is C14H10 while the empirical formula is C7H5.

Can the concentration of hydrochloric acid increase the rate of the reaction between magnesium ribbon and hydrochloric acid?

Science Coursework – What factors effect the rate of reaction between magnesium and hydrochloric acid? Background Knowledge There are four factors that can affect the rate of reaction and they all rely on the collision theory. This is basically how hard and how often particles collide with each other. The more and harder they collide, the faster the reaction time will be.

Overall, the results were almost as expected. It was predicted that Magnesium and Calcium would have a similar reaction will the hydrochloric acid and produce approximately that same quantity of hydrogen gas. However, the results demonstrated that the Calcium reacted more vigorously than expected and produced a larger quantity of hydrogen gas. The reaction which occurred whilst using Magnesium resulted exactly like the prediction. It was expected that the metal would bubble, eventually dissolve and produce gas which would potentially displace the water in the test tube. With the reaction involving Calcium, it was not predicted that it would heat up the conical flask and react as violently. It was expected that the Tin would either have a

Magnesium is the most important nutrients in the energy powerhouse. The heart is benefited by magnesium. It also helps protect the blood vessels. Magnesium is aforementioned to prevent heart attacks and strokes. Diabetes is said to be prevented by magnesium. The adult body contains about 25 g of magnesium. Enzymes are turned on by magnesium. Magnesium protects from a number of chronic diseases. For instance, our body balance, avoid being sick, and can do well under stress from the help of magnesium. Magnesium interacts with most all of the systems in the body. Magnesium is stored in the body for future use. Magnesium is important in muscle relaxation and heart health. Magnesium sends messages in the brain and nervous system by the

The acid in your stomach is strong enough to dissolve razorblades. Hydrochloric acid is the type of acid found in your stomach. Because of this you get a new stomach lining, every three to four days. The mucus like cells lining the walls of the stomach would soon dissolve because of the strong acid in your

The purpose of this lab was to test the law of conservation of mass by comparing the total mass of the reactants in a chemical reaction with the total mass of the product.
