The Importance of Numbers in Chemistry

The reaction "ICE" table demonstrates the method used in order to find the equilibrium concentrations of each species. The values that come directly from the experimental procedure are found in the shaded regions. From these values, the remainder of the table can be completed.

9. Chemists meet the demands of energy by finding ways to conserve, produce and store energy.

The importance of significant figures in chemistry is that when doing any type of experiments, accuracy and precision is key. Being exact is extremely important during any sciences and math.

The objective of EDC141: The Numerate Educator was for students to obtain the chance to develop their mathematical skills, build mathematical competency, and positively chance their disposition (as a pre-service teacher) towards the importance and the functionality of maths. The key to success is to learn from one’s mistakes and work (by practicing mathematical questions) to further improve one’s results. This I managed to do by increasing my Mathspace results from 64% to 68% (as shown in Appendices 1A). The Australian Curriculum focuses on developing student’s capabilities in six areas: number, Algebra, Geometry, measurement, statistics and probability. Using evidence from the Mathspace test results, the NAPLAN results and activities of ‘What

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:

2. The least precise measurement was the temperature but more specifically the freezing points of the solutions and solutes. Due to the freezing point only having two significant figures, the data is limited to two significant figures as well.

We can use this information for simple division, multiplication and even when multiplying and dividing larger numbers. This information can be used when cooking, grocery shopping, building things etc..

Since the p-value of 0.6943 is greater than 0.05, the data is said to be statistically significant. This means the null hypothesis is not rejected and the observed values meet the expected values.

2. Ozonolysis of compound Z yields the products shown below. What is the structure of Z?

While in table 1 it is shown that we had to round to two decimal places

Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation

It is my privilege to recommend Michael Crist for selection into medical school based on my direct observations of his capabilities. Michael was my student within a very stringent Chemistry Course, “Chem 1111,” in the summer of 2015. During this time frame, I found Michael to be a self-motivated, proactive, determined individual who is capable of achieving excellence despite demanding challenges. This, to me, is a strong indication that Michael can handle the arduous nature of medical school.

Without the use of significant figures, numbers in chemistry wouldn’t have any meaning. I could say 2g when I’m really

There are five main braches of chemistry: Organic Chemistry, Inorganic Chemistry, Analytical Chemistry, Physical Chemistry, and Biochemistry. Organic chemistry and Inorganic chemistry are self-explanatory, as organic chemistry is concerned with the chemistry side of carbon and living things, and inorganic chemistry is the branch of chemistry that deals with the interaction between and structure in inorganic compounds.

Alchemy is considered the precursor to modern chemistry. When you think of chemistry, usually you think of an exact science; something very meticulous. Truthfully, it is. To be accurate and to obtain precise and desired results, it must be accurate. Alchemy, however, was not an exact science, it was a primitive approach to the elements and usually they looked to a deity to actually initiate chemical reactions. Thus we separated them, but for good reason. In today's time we us instruments to give us exactness and precision that mankind had formerly ignored. Throughout time you will see that mankind has used chemistry to solve its most complex of problems and build a world that 7 billion people have come to know as home.
