Data Collecting and Processing Raw data Table of raw data Qualitative observation: At the start of the experiment‚ the crystals were blue. During the heating‚ the crystals turned white which means that they lost their water molecules. The source of hydrated copper sulphate consists of both small grains and large grains of the salt. Therefore during the heating process‚ the smaller grains of the hydrated salt turned from blue to white in just 1 minute. In other words‚ there is an uneven heat

Our Decisions Determine Our Destiny Our whole life is based on the decisions we make‚ whether it is big decisions like if we choose to go to college‚ get married‚ or have kids‚ or even smaller decisions such as if we decide to turn left or right on a walk. All of these decisions that we make in life can change our future‚ and of course we all want to make the right decisions so that we have a good future. God is so wonderful that he equipped us with moral law‚ which provides ways to tell the difference

FACTORS THAT WILL DETERMINE THE DEMAND FOR HOTELS IN THE UK Hotels play a big role in the hospitality industry‚ they provide not only a place to stay and eat for travellers but also a good quality of service which is sometimes compromised by some hotels due to other factors. As the number of traveller increases every year‚ thus the demand for accommodation increases. We will be looking on the Microeconomic Environment of hotels in United Kingdom and determine different factors that affect consumer

Chemical reactions proceeding until all the reactants are used is a common misconception. Chemical reactions actually behave differently. The general reaction equation is a A + b B → c C +d D in this equation A and B are the reactants forming the products C and D. However‚ unlike the common thought that the reaction ends when it runs out of A and B it actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b

A Method to Determine Reasonableness and Feasibility of Noise Abatement at Special Use Locations I. INTRODUCTION Most states have policies in place that determine whether noise abatement is necessary and reasonable/feasible for Type I projects. These policies mirror federal guidance and apply to various land uses near the proposed project. Special land use facilities such as parks‚ churches and schools are included in the policy as far as when abatement may be necessary (i.e. the Federal Highway

The synopsis of this article relates to how a group of researchers from Riverside‚ California have revealed a molecular mechanism that directs the chance and role of cells during the process of animal development. The researchers’ discovery shows remarkable findings that are promising in the advancement of cancer and stem-cell research. The hypothesis of this article relates to even though each individual cell contains the complete DNA code‚ only small portions of this DNA code are activated. Therefore

vacation. What did you do to fill those two months? Most kids would just sit around all day waiting for school to start. But if you were out trying new things and meeting different people‚ Thomas Jefferson would be proud. As Jefferson once wrote: "Determine never to be idle... It is wonderful how much may be done if we are always doing." I agree with this statement and believe that staying active will ultimately lead to progress. For instance‚ while Bob sits waiting for the jobs to come to him‚ Sally

Antibiotic test‚ such as the Kirby Bauer Method‚ are used to determine susceptibility to various antimicrobials. Why are they not used to determine resistance? a. They grow a resistance to antibiotics and antimicrobials. Kirby Bauer is used to determine diffusion of a disk‚ to measure the effectiveness of antibiotics towards pathogenic microbes. 4.

HOW DEMAND DETERMINES OUTPUT IN THE SHORT RUN Typically‚ firms that supply intermediate goods such as steel rods or other inputs let demand not price determine the level of output in the short run. To understand this idea‚ consider an automobile firm that buys material from a steelmaker on a regular basis. Because the auto firm and the steel producer have been in business with one another for a long time and have an ongoing relationship‚ they have negotiated a contract that keeps steel prices
