Procedure: The addition of 4.0 mL cyclohexanol‚ 1.0 mL of 85% phosphoric acid‚ and one boiling chip‚ were all added to a 10 mL round bottom flask that would be attached to the end of an assembled simple distillation set up. A sand bath was placed atop a hot plate‚ and the simple distillation mechanism was lowered into the sand bath with the bottom most piece (the 10 mL round bottom flask) submerged about half way. The distillation process was completed after a sufficient amount of liquid distillate

Introduction: Aim: To find the relationship between the length of a simple pendulum and the period of oscillation. Research question: How does the string length of the pendulum affect the period of oscillation? Prediction: The longer the string‚ the longer it will take to make one complete oscillation. Variables: Independent variable: Length (L). Dependent variable: Period of oscillation (T). Controlled variable: Mass of the plasticine. Tools & Materials: Stopwatch. Ruler. String. Plasticine

An Essay On Poop Stains Issues surrounding poop stains can never be over analyzed. I find my self constantly drawn back to the subject of poop stains. While it is becoming a hot topic for debate‚ it is important to remember that ‘what goes up must come down.’ Since it was first compared to antidisestablishmentarianism much has been said concerning poop stains by so called ’babies’‚ whom I can say no more about due to legal restrictions. With the primary aim of demonstrating my considerable intellect

EXPERIMENT 2 Measurement of g: Use of a simple pendulum OBJECTIVE: To measure the acceleration due to gravity using a simple pendulum. Textbook reference: pp10-15 INTRODUCTION: Many things in nature wiggle in a periodic fashion. That is‚ they vibrate. One such example is a simple pendulum. If we suspend a mass at the end of a piece of string‚ we have a simple pendulum. Here‚ the to and fro motion represents a periodic motion used in times past to control the motion of grandfather and cuckoo

Matthew Mannetta Simple Harmonic Motion Lab Report Introduction Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s Law. In this lab‚ we will observe simple harmonic motion by studying masses on springs. In the first part of this lab‚ you will determine the period‚ T‚ of the spring by observing one sliding mass that is attached to two springs with the spring constant k‚ and attached to a hanging mass by a string

Simple Harmonic Motion Lab Report In this lab‚ I will study the principles of simple harmonic motion using an oscillating pendulum. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the

Gram Stain: The important part of this experiment is being able to determine a bacterium based on its cell wall structure. It also helps indentify if the unknown organism is a Gram positive or Gram negative. This is the initial step that must be taken before any other lab procedure may continue on to ensure the purity is present‚ the arrangement of the cells‚ and the shape the cell has. The staining of the cell starts off with using the primary stain‚ Crystal Violet which is a purple color‚ to begin

secret ingredient to many mouthwatering Filipino delicacies such as pancit palabok‚ Leyte kinilaw‚ beefsteak Tagalog‚ and arroz caldo. One of the most basic Filipino dipping sauces is made with soy sauce and calamansi juice‚ called toyomansi; and a simple‚ yet flavorful marinade is a blend of soy sauce‚ calamansi juice‚ vinegar‚ pepper‚ and garlic. While many growers see the calamansi as tiny decorative oranges and mostly ornamental‚ they are finding that the trees are problem free and easy to cultivate
