radius affects the reactivity of an atom‚ as the bigger it is the bonds become weaker. As electrons are further away from the nucleus‚ the attraction between it (negative and positive forces) are not as strong‚ where electrons are able to move easily. A smaller atomic radius has a stronger bond between electrons and nucleus making it harder for other atoms to get it’s electrons. The

Observing Enzyme Activity Purpose: The purpose of this experiment was to test whether the pH affected the enzyme reaction rate. Hypothesis: If the enzyme is in a basic solution‚ then it will react faster because the enzyme (catalase) reacts better in basic solutions. Materials: 10 potato cubes (1 cm3) -Pipet Baking soda solution -50 ml glass beaker Bleach Water Lemon juice Vinegar 5 glass test tubes Drying rack Timer Graduated cylinder Hydrogen peroxide Procedure:

The reactivity series is the known series of how metals should react. It places Calcium as the most reactive (of the metals being tested in this experiment)‚ followed by Magnesium‚ Aluminium‚ Zinc‚ Iron‚ Tin and finally‚ as the least reactive (of the metals being tested in this experiment)‚ Copper. However‚ the results this experiment produced did not follow this trend. If the metal that produces the most hydrogen gas is considered the most reactive‚ in this experiment magnesium was most reactive

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Aim: To compare the reactivity of various metals by observing their reaction with hydrochloric acid. Materials: 2 M hydrochloric acid Detergent Test tubes and test tube rack 0.5 pieces of magnesium‚ aluminium‚ iron‚ zinc and cooper Sand paper Ruler Timer Bench mat Method: 1. The surface of the magnesium was cleaned with a piece of sandpaper 2. The Magnesium was placed into a test tube 3. Three Drops of detergent were added to the test tube 4. 2cm of hydrochloric acid was added

The purpose of the lab “All in the Family” was to compare the reactivity of the halogens Chlorine‚ Bromine‚ and iodine by observing the reactions between their elemental forms and their ionic forms. To accomplish this experiment‚ we first added a squirt of pet ether to two test tubes. Then‚ we added the same amount of Cl2 to both of the tubes‚ shook the mixtures‚ and recorded the color that resided in each mixture as the initial color. After‚ a squirt of NaBr was added to one test tube‚ and a squirt
