Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to

CHAPTER I THE PROBLEM AND ITS SETTING INTRODUCTION This research paper is all about the factors that affect the behavior of high school students in dealing with other people. The researcher chose this kind of problem to be aware of the distinctive behavior of her fellow schoolmates‚ classmates‚ batch mates‚ etc. The researcher conducted this study to know the effective implications for the behaviors.

Acid Base Titration bre’ana March 1‚ 2013 Purpose: The purpose of this experiment is to determine the concentration of a solution of NaOH by titration with a standard solution of HCl. It was also the purpose to determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH. Introduction: Using the method of titration is how the experiment gets to the conclusion of the concentration of a solution. When doing this experiment‚ measurement is very important

affected by different factors. We cannot deny the fact that these factors could really affect the student’s academic performance. Some students who are influences by peer groups or barkadas tends to cutting class which may results their low academic performance. The peer factors like smoking may cause disease that would become hindrance to their success and this differs from other insight about those factors and their purpose and existence.

LAB 6. ACIDS AND BASES: PH AND BUFFERS PURPOSE: To determine the pH of common acids and bases using a pH meter‚ pH paper‚ and red cabbage indicator. To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic

Background of the story Students between the ages of 5 and 18 years of age are expected to learn in school. It is their primary job in society‚ and it’s possibly the one thing that will prepare them to become productive members in their adult years. What they learn will also determine the choices they’ll make when they enter the workforce or continue onto higher education. In order for students to learn there are several factors that must be considered. Most of these factors are external; they deal with

This affects the intermolecular attractions because the more polar a molecule is the stronger its attraction to other polar molecules will be. The next two alcohols were ethanol and propanol which followed the predicted pattern at 13.2 ºC and 5.3 ºC respectively

Modern methods of food production have altered radically from processes used in the past. Many food producing companies have invented their own improved techniques of cooking. Most of these procedures contain numerous different forms of chemical additives and one of the newest chemical substances that will enhance food flavor is monosodium glutamate (MSG). Even though it has no taste of its own‚ it intensifies considerably the taste of a wide variety of food as well as revealing flavors that could

To determine which factors affect the resistance of a conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor of affecting the resistance
