I am investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must

different sucrose concentrations on potato stripes which have been submerged in a range of solute sucrose concentrations. II. Background Information Osmosis is one of the four methods of moving particles across membranes along with simple diffusion‚ facilitated diffusion‚ and active transport. Water is able to move in and out of most cells freely. Sometimes the number of water molecules moving in and out is the same and there is no net movement‚ but at other times the molecular movement from one direction

The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass at 15.2% for 0% concentration. Overall‚ the higher the concentration of the

INTRODUCTION Many important reactions and processes in materials occur by the motion of atoms in the solid (transport)‚ which happens by diffusion. Inhomogeneous materials can become homogeneous by diffusion‚ if the temperature is high enough. When substances are brought in contact with each other they intermix‚ this property is known as Diffusion

Activity FOUR There is a direct relationship between the MWCO and the filtration rate; the higher the MWCO‚ the higher the filtration rate. Powdered charcoal is the solute that did not appear in the filtrate when using any MWCO membranes. As pressure increases‚ the filtration rate also increases‚ as long as the MWCO does not decrease. Since we have no control over the MWCO of a living membrane‚ we can increase the rate of filtration by increasing the pressure. The molecular weight

understand the process of fermentation of yeast in different concentrations of sucrose. The experiment worked with yeast and sugar (sucrose and glucose) to determine the rate of fermentation by testing the pressure of C02 in the test tube. The experiment tested the metabolic capability of yeast anaerobically meaning no oxygen was present (this was ensured by the thin layer of oil on the top of the solution). This means that the metabolic rate of the yeast could be determined by testing the pressure in

amount of sucrose in the dialysis bag affected the amount of mass each bag loss or obtains. All the tubes contained different amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because
