The chemical equation for this experiment is Mg + 2HCl MgCl2 + H2 Prediction My prediction on this experiment is when the temperature is kept at low degrees the reaction of magnesium strips with HCl will be slower but when the temperature is raised to a higher degree the magnesium strip will react with HCl much faster. So when the particles move faster they would have more collisions between them. In cold temperature In hot temperature Example when magnesium strip…

Introduction There are many types of snail but not less than 14 of these are edible. The most popular and most lucrative to breed for consumption and commercial purposes are achachatina marginata, archatina archatina, helix pomatia and helix aspersa. The first two are usually very big, weigh between 150 and 200g, lay between 5 and 300 eggs per batch and 8 times each growing season, and measure 90-130cm in length. The last two species of snail are helical in nature,…

Aim: I want to find out what ions cause hardness in water and the reasons as to why certain ions have an effect and others don't. Background information: Calcium hydrogen carbonate is the main cause of hard water. It forms when rain falls on rocks of limestone and chalk. These are made of calcium carbonate, which is not soluble in water. But rainwater contains carbon dioxide dissolved from the air, which makes it acidic. So it reacts with the rocks…

An investigation to find out how the concentration of acid affects the rate of reaction between hydrochloric acid and calcium carbonate (marble chips) Planning The aim of my investigation is to find out how changing the concentration of acid affects the rate of the reaction between CaCO3 and HCl. To make my experiments fair tests, I will only change one variable: the concentration of the acid. I will have to keep the volume of the acid, the mass and size…

I am going to see if changing the concentration of acid affects the speed at which it reacts with marble chips. Marble chips + Hydrochloric acid ( Carbon dioxide + Water + Calcium chloride CaCO3 + HCl ( CO2 + H2O + CaCl2 I will measure how much gas is given off by using a tally counter to count how many bubbles of gas are given off and measuring the volume of gas produced. Diagram: Apparatus: 5g medium marble chips…

The aim of this investigation is to find out what antacid tablet works the best. We will be finding out which antacid tablet is cost efficient and which antacid tablet if effective by this I mean the one that can hold acid the most This can be done by using a pH probe, and seeing how long it takes to make the antacid tablet turn the HCl back to an acid. The best antacid tablet will be cost effective, so…

In partial fulfillment of the requirements for CHM031: Chemistry for Engineers Julhany B. ButongkaySeptember 07 2019 THE CONCRETE History In the world we live in, buildings and infrastructures are common in our sight. These structures provide our basic needs like shelters, it also connects us to the place we wanted to go. So, these structures were made to be strong, durable and should last longer. Concrete is one of the materials that make our shelters safe for us. Through the years,…

Introduction Background Of The Study Inventories are items that are kept in stock for further processing or resell. Inventory is also the current amount of a product that a business has in stock. High levels of inventory or buffer inventory enables an organization to cope with surges in demand. But this would entail a considerable cost outlay, in holding high levels of inventory. Inventory management is primarily concerned with specifying the quantity and the reorder time in the manufacturing outfit.…

Acknowledgements From the bottom of our hearts, we would like to express our greatest appreciation to the following persons who supervised and guided us in pursuit of our investigatory project. First of all, we would like to thank ourselves, because through many failures and hardships, we remained strong and determined in finishing the research paper. To our research advisers, Ms. Ma. Pilar P. Carmona and Ms. Sasha Gliponeo for their assistance in making the paper and reinforcing the use of…

Use of concrete dates back to 3000BC and was only used for industrial purposes. But as time passes it has become one of the most standard materials used and even plays a major role in the infrastructure sector. This fact itself makes it a potential subject for researchers who are in line to concrete production and development. However present-day research shows that some of the current concrete treatment methods, such as the application of chemicals and polymers in the production…

Biosphere II was a project done in Arizona received recognition on 26th September 1991. Eight people; four men and four women were used in the experiment. Biosphere 2 was an air tight structure with its base made of steel pan and surrounded by an above ground structure that was made of glass and steel. Inside the biosphere was all that could be found in the real world. There was a desert, a marsh, a rain forest, a savannah, an agricultural…

Centuries before to cure the common diseases mostly people were used to the natural ingredients. The use of natural resources can be thought a way of glorifying the information about the lifestyle of past people. Natural health remedies have very powerful and healthy effects. The at-home pharmacist There are so many ways of self treatment nowadays but always remember some natural remedies don't play effectively like medicine or maybe it will be risky for some people with specific conditions. So…

Introduction According to Arrhenius definition, acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base, a method called acid-base titration is used. The end of the titration has been reached when…

SYNOPSIS The purpose of this experiment is to use the back titration method to determine the percentage of calcium carbonate in toothpaste. Instead of using standard titration methods where an acid is titrated directly using a standard solution of a base, back titration is used because the sample to be analysed, CaCO3 does not dissolve in water. Hydrochloric acid and sodium hydroxide are the reagents used in this experiment. The precise measured amount of HCl is added to the weighted…

The purpose of this experiment is to examine the percent yield of a precipitate in a double displacement reaction. A solution of calcium citrate and sodium carbonate were mixed together, then the products were filtered out as so only the precipitate remained. The filtered paper was then dried and the mass of the precipitate in the experiment divided by the theoretical mass of the precipitate from the calculated gave the percent yield. The percent yield that was acquired is about…

Philippines’ economic status nowadays depends mainly on the production of crops. As we all know, our country has also the advantage when it comes to technology and especially in businesses. Likely in producing products that’s essential to us Filipinos. From this statement, we could conclude the production of materials by factories. Chemicals and other harmful and toxic liquids being used by these factories would greatly affect the soil. Vehicles and other chemical-producing machines penetrate into the soil and also make…

Abstract: In this experiment Stoichiometry of a Precipitation Reaction, the main objectives were to use stoichiometry to calculate the theoretical yield of CaCO3 that precipitates from the reaction between Calcium chloride, Dihydrate and Sodium carbonate, and then compare that value to the actual yield. In order to do this accurately, we must be able to measure the products and reactants with accuracy. The last objective of this experiment is to calculate the percent yield of the product produced. When 1.0…
