## A Chemical Formulas !: What Is A Chemical Formula?

!!!What Is A Chemical Formula? Everyday, we encounter chemical substances. In our household alone, substances that we use to clean, and those that are staples in our medicine cabinet, as shown in the picture below, are made up of chemical substances. These chemicals that we use everyday are made up of atoms of a fixed proportion and these atoms are arranged in a certain way. How do we know what the atoms are, their proportion as well as their arrangement? This information can be gathered from the

## How To Write A Fertilizers Lab Report

During week 1 of this experiment, we recorded common components of fertilizers and then went on to find the chemical formulas involved in creating them. The second week we began the process of comparing three authentic ions we had established in the first week to ion samples to discover other properties they might contain. We decided to discover these different ingredients

## Copper Sulfide? Who Knows?

The mass of the copper coil was found. The copper coil was placed in a crucible. A sulfer powder was added to the crucible to cover the copper coil. The cover was placed on the crucible. The Bunsen burner was lit. The covered crucible was placed on the triangle, on the ring stand, above the

## Rearranging Letters in a Word

coursework I am going to investigate the number of different ways I can write a word, re-arranging the letters without having any repeats of the sequence. After I have finished my investigations I will try and use my findings to draw together a formula which I could then use to find out how many ways a word can be written for any chosen word. My initial step is to write the name 'EMMA' with as many different arrangements I can find. ======================================================================

seen. In this coursework I will be finding out the global formula for the total number of hidden faces for any number of cubes in any way positioned. To find this out I will be testing various numbers of cubes in different positions. This will enable me to find out several different formulae. Using the formulas found I will then be able to find out the global formula. I am generating only 3 formulae to get to the global formula. 1 row 6 faces 1 cube 1 hidden face 1 row 12 faces

## Portland Cement

PORTLAND CEMENT Chemical composition. Portland Cement is made up of four main compounds: tricalcium silicate (3CaOSiO2), dicalcium silicate (2CaOSiO2), tricalcium aluminate (3CaOAl2O3), and a tetra-calcium aluminoferrite (4CaO Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as C3S, C2S, C3A, and C4AF, where C stands for calcium oxide (lime), S for silica, A for alumina, and F for iron oxide. Small amounts of uncombined lime and magnesia

## The Molecular Formula of Succinic Acid

The Molecular Formula of Succinic Acid The relative formula mass is the mass of 1 molecule of succinic acid compared with 1/12th of the mass of an atom of carbon-12. This is obtained by adding together the relative atomic masses of the atoms within the molecule according to its written formula. However we do not know the exact formula: HOOC(CH )nCOOH Where n is a whole number between 1 and 4 So to calculate the relative formula mass I must use the formula m = n ×Mr and

## The Zone Diet

It seems like everywhere you look there is some new diet plan making miraculous promises of weight loss through pills, plans, and formulas. The zone diet is no exception. The zone diet was developed by Dr. Barry Sears in his book," Enter the Zone" which was on the bestseller lists for weeks. The zone promises high energy, weight loss, and no hunger to those willing to follow the simple set of zone rules. It sounds great you say, but does it really work? What is the Zone? The "zone" was first

## Measurement - Mathematic Reform

dimension. Instructional programs from prekindergarten through grade twelve should enable students to understand measurable attributes of objects and the units, systems, and processes of measurement. Also, apply the appropriate techniques, tools, and formulas to determine measurements (NCTM, 171). This paper will describe how those ideas are developed in grades three through five. The first and most basic standard for measurement at this level is being able to understand measurement attributes that we

## Srinivasa Ramanujan

solve the quartic. It was in the Town High School that Ramanujan came across a mathematics book by G. S. Carr called Synopsis of Elementary Results in Pure Mathematics. Ramanujan used this to teach himself mathematics. The book contained theorems, formulas and short proofs. It also contained an index to papers on pure mathematics. By 1904 Ramanujan had begun to undertake deep research. He investigated the series (1/n) and calculated Euler's constant to 15 decimal places. He began to study the numbers

square and a 5 by 5 square. After doing this, I will try to find a formula that can find the difference in any sized square. I will then decrease the size of the grid so that it becomes 9 by 9 and will then do exactly the same method as I did before and then I will do this again but with a 5 by 5 grid. I will then work out formulas for both of these grids, to find the difference. I will then use algebra to prove that my formulas are able to work out the correct difference. To investigate further

## Math Investigation of Painted Cubes

dry, the large cube was cut up into the smaller cubes, all 8000 of them. From there, I had to answer the question, 'How many of the small cubes will have no red faces, one red face, two red faces, and three faces?' From this, I hope to find a formula to work out the number of different faces on a cube sized 'n x n x n'. Solving the Problem ------------------- To solve this problem, I built different sized cubes (2 x 2 x 2, 3 x 3 x 3, 4 x 4 x 4, 5 x 5 x 5, 6 x 6 x 6, 7 x 7 x 7, 8 x 8

We also use the calculator, especially a calculator with graphing functions, to make graphs and to see what the math formula actually did. We can see what it measures and actually what the formula means. In another class called Senior research, we are using the ANOVA (Analysis of Variance) which is a data analysis tool that

foundation of Brahmanic Hinduism. The main body of Rigveda's text contains mostly hymns dedicated to the ancient Hindu gods. The second text of Vedas is called the Yajurveda. It was written in 1200 BC. The main themes of Yajurveda are the sacred formulas recited by Brahmin priests during the performance of sacrifices. The third book of Vedas, Samveda (1100 BC), was also known as the Veda of chants. In its essence Samveda was an anthology of Rigveda writings. The last Veda is the Arthaveda (1200 BC)

## Elasticity of Demand for Lottery Tickets

Elasticity of Demand for Lottery Tickets Elasticity is the responsiveness of demand or supply to the changes in prices or income. There are various formulas and guidelines to follow when trying to calculate these responses. For instance, when the percentage of change of the quantity demanded is greater then the percentage change in price, the demand is known to be price elastic. On the other hand, if the percentage change in demand is less than then the percentage change in price; Like that

## The Formula of Succinic Acid

The Formula of Succinic Acid Succinic acid is a diprotic, which means it donates two protons per molecule. Succinic acid can be completely neutralised by sodium hydroxide. The indicator most suitable for this experiment is phenolphthalein, it is colourless in acids and pink in alkalises. The half way stage is about pH 9.3, this is when it will either change from colourless to a very pale pink or from pink to colourless. To determine the relative formula mass of succinic acid I am going to

## The Mechanics of War

Recently a new trend has taken up Wall Street. Savvy broker firms have realized that the market is probably controlled by some rules, and those rules have to be found to make more money with the least risk. They hired many mathematicians to look for any formulas that would seem to express the market. Those analyzed previous market trends and used laws of statistics to try to predict the “future” of the market. The funny thing is that at times this approach actually worked. It yielded a slightly more than
