Investigating travel and tourism industry There are 8 main components of travel and tourism industry. They are : 1- Accommodation- this is the most important component in the travel and tourism industry. Accommodation may include hotels‚ guest-houses‚ lodging-houses‚ bed and breakfast‚ inns and motels. 2- Transport- a good transportation system is very important for a travel and tourism industry‚ whether people are on business‚ travelling for leisure or visiting friends and

Zachary Bishop The effect of distance between dominoes and time taken to fall Introduction By collecting data whilst keeping all variables constant apart from the independent and dependent variables of an experiment‚ it is possible to determine a relationship between them. One relationship that can be observed in a laboratory is the relationship between the distance (denoted by symbol d) of separation of dominoes in a domino chain and the time taken (denoted by symbol t) for all dominoes to fall

LABORATORY 3: LABORATORY 3: Basic Chemistry for Investigating Living Systems Abstract The purpose of this experiment was to explain how colorimetry can be used to qualitatively detect cellular chemical components; to chemically differentiate between proteins‚ sugars‚ starches‚ and lipids; to identify the roles of molecular components in living systems; to comprehend the value of using a systematic approach to research; and to describe why hypotheses‚ controls‚ standards‚ and quality control

concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that

data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order. Using this information‚ the rate constant was determined to be 0.408 M-1S-1‚ the units indicating that the reaction was a second order

the least. Also‚ 0.5mM ONPG solution has the highest rate of enzyme activity and it is the most efficient as the enzyme activity of the ONPG solution continues even though the other concentrations of ONPG solution has already stopped the enzymatic reactions as the substrate is already used up. Introduction This experiment is to study and measure the enzyme activity using a spectrophotometer and to understand the practical aspects of handling enzymse. This is done when the colourless ONPG is split

Kinetic Expressions (Kinetics) has been taking place at Berea College for 20 years. This year the team celebrated its 20th by revisiting a choreography that was performed at the first Kinetics and were very purposeful of who they allowed to choreograph in this production. This will be a critique of some of the dances performed; it will go into detail about each dance‚ analyze the movements and reveal the message. The opening act to Kinetics this year was the choreography that was performed at

Kinetic energy is increasing between letters A-B‚ C-D and E-F. Based off the observations‚ in phase A-B Tert-Butyl Alcohol stays a solid‚ in phase C-D Tert-Butyl Alcohol stays a liquid‚ and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the

2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make
