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 whether or not carbon dioxide has been formed Delivery tube

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

Marble Statue of a Wounded Warrior Marble Statue of a Wounded Warrior is a Roman statue‚ crafted in the second century A.D.‚ as a copy of a bronze Greek statue cast between 460 and 450 B.C. Though sculpted with obvious technical aptitude‚ Wounded Warrior is riddled with anatomical imprecision and is inhibited by a reluctance to depict the unsightliness of injury in combat. The first time I laid my eyes on this exquisite artifact‚ I was astonished by its fierce presence. The orientation

Race Your Marbles to Discover a Liquid’s Viscosity Which Liquid Has the Highest Viscosity? In this project we will determine the viscosities of 5 separate liquids. The liquids we will test are corn syrup‚ honey‚ vegetable oil‚ milk‚ and water. We will find their viscosities by dropping a marble into each of these liquids and measuring the time it takes for it to reach the bottom. Before we conduct the experiment‚ we must first understand what viscosity is. “Viscosity is the quantity that describes
