Date of Experiment: 6/9/15 Report Submitted: June 10‚ 2015 Title: Observations of Chemical and Physical Changes Purpose: the purpose of this lab experiment is that I will be able to decipher the difference between a chemical and physical change. I will be about to tell whether a chemical change has occurred during the experiment or if it was a physical change and I will be able to answer why it is either one. Procedure: In the lab experiment‚ I mixed different types of chemicals

EXPERIMENT 1 COLLIGATIVE PROPERTIES OF SOLUTIONS Date: December 03‚ 2013 Locker 21 Members: Vanessa Olga Dagondon Christine Anne Jomocan Janica Mae Laviste Nablo Ken Menez A. TYPES OF DISPERSED SYSTEMS Results and Discussion The first part of the experiment aims to differentiate the different dispersion systems. In this experment‚ three systems are introduced: true solution‚ colloidal dispersion and coarse mixture. The said three systems are classified through a property of colloids known as the

from systematic errors (deterministic error) or random error (not deterministic error). In this experiment‚ the group measured the diameter of sphere using different kinds of measuring devices (foot rule‚ vernier caliper‚ and micrometer caliper) in order to achieve accuracy in the scientific measurements. After experimenting‚ it was revealed that the micrometer caliper has the lowest percentage of error. 1. Introduction In the early days‚ people used mostly human body parts for measuring. And because

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Description This program will determine the usable area of a house. The rooms are rectangular in shape and maximum of four rooms are allowed to be calculated at once. It will use the area formula for a rectangle to find the usable area of each room and once the calculation are made for each room it will print out the total usable area of a house to the output screen. Analysis This program will calculate the usable area in square feet of a house with a maximum of four rooms that are rectangular
