Carbonates react with strong acids to give off carbon dioxide and water. Marble is calcium carbonate and thus behaves in the same way: CaCO3 (s) + 2HCL (aq)  CaCL2 (aq) + H2O (l) +CO2 (g) In this experiment‚ I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction. I predict the higher the temperature‚ the faster the reaction rate. This is due to the kinetic theory. The more heat
Premium Calcium carbonate Carbon dioxide Chemical reaction
Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

Investigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation

This experiment is to show how much carbon dioxide is produced during the reaction between an acid (hydrochloric acid) and marble. Equipment: Hydrochloric Acid (20ml) - 0.5M‚ 1M‚ 2M Marble Chips (2g per test) Large Measuring Cylinder Plastic Bowl (3/4 full of water) Rubber Tubing Glass Conical Flask Stopwatch Method The first thing that we did was fill the plastic bowl with water. We only filled it up 3/4 of the way because otherwise the water displaced into

Hypothesis: The higher the concentration of hydrochloric acid‚ the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction. The lower the concentration‚ the weaker the reaction will be as there will be fewer particles so less chance of a collision and a lower rate of reaction. Equipment: Conical flask – to hold the hydrochloric acid and marble chips Boiling tube – to hold and indicate

Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid Aim. In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by

Introduction: Temperature - Is a measure of the motion of particles‚ increasing the temperature will cause the particles to move faster because the reactant particles have more thermal energy from the heat. When particles move faster‚ more frequent collisions will occur and the collisions are more violent. This should increase the reaction rate. This will result in the particles colliding more frequently and increasing the speed of the reaction. Also when they have more energy there will be more

Rate of Reaction Experiment Introduction : in this term in chemistry class I was learning about rate of reaction. As defined by the Britannica encyclopedia‚ a chemical reaction is a process where one or more substances (reactants) are converted to one or more different products because of the rearrangement of atoms of the reactants. For the reaction to occur‚ the particles must collide with each other and in order to succeed there must be enough energy for the collision because a collision with little
