What Chemistry Means to Me

When mining gold there is about 1 ounce of gold per ton though when mining on the surface that statistic drops to about 0.5 ounce of gold per ton. Gold is highly valued at about $120,000 per truck this is because gold is malleable, and it never loses luster or rusts. Next, copper which is also a valued metal because of its specific properties, it conducts electricity and bacteria doesn’t like to come in contact with copper. Many people have found the value in copper and trade copper in the same way stocks and shares of companies are traded. And finally bronze which is made of 80% copper and 20% tin, bronze is used in the manufacturing of bells. Bronze is used in the making of bells because when copper, a pure substance, is hit it creates a ripple effect making the bell easy to dent, with tin the rows of copper atoms are more stabilized, but too much tin can result in a bell cracking as the Liberty bell did.

As for metal, it has many uses. In fact, modern civilization has thrived off of things where iron is used like: buildings, car frames, bridges, and much more.

First of all, this is a theory. A theory is when a system of ideas are intended to explain something such as an event. There are many different theories in the world. Theories can be crazy and some of the theories are really believable. Theories can be about anything if you think about, all you need are the facts to back it up. Imagine all the theories that can be made. Some popular theories are that chemicals

Chemistry relates to everything we touch, see, smell, hear, and taste because atoms make up everything in the universe. Chemistry influences so much in our everyday lives that it is hard to think of an activity that does not involve a chemical process in some way. The science also plays a major role in the human body. Our bodies are made up of chemicals, in fact almost 96% of our body mass is made up of four different elements: hydrogen, oxygen, carbon, and nitrogen. Besides the physical way I am affected by elements, chemistry also majorly affects me in my line of work as a certified nursing assistant. As a certified nursing assistant I work in a nursing home and

Out of all of the skin care products in the world, your bathroom cabinet needs to be filled with products researched and designed by me. When I entered high school, I discovered my passion for selecting lip sticks, lip glosses, lotions, perfumes, and makeup foundations. You name it. After learning about the connections between the information in my chemistry class and these items, a light bulb went off! I maintained an A average in chemistry throughout the whole year! Additionally, in 2014, I became a student in the Academy of Engineering and Technology, which also heightened my interests in chemistry. In a science fair at that academy, there was a chemistry course where we made colorful slime, and during that process, I learned that I get an adrenaline rush when I am mixing different chemicals together to see what the outcome is. Majoring in chemistry at Norfolk State University will definitely prepare me for a very successful future in chemistry! My ultimate goal is to conduct research and development for chemical cosmetics. I plan to obtain employment at the greatest companies in the world such as L'Oréal and Avon.

I would have to agree chemistry is a central science because it can be used in different aspects of science such as biology, medicine, physics and more. It brings a lot of the sciences together. Chemistry connects those other parts of science such as physical science. An example would be the makeup of how medicine is created and also how the body chemistry uses the medicine into the body.

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter.

A chemical reaction is a process that involves change of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The key concepts of a chemical reaction are:

1. Decide if the mineral is metallic or non-metallic based on its luster and streak.

Chemical reactions make new things by rearranging other things. In a chemical reaction, the main change that occurs relates to the way atoms are bonded to each other, in order to change those connections, bonds must be broken and new bonds be formed.

Iron began being widely used across Central Europe during the 8th century, and across Northern Europe during the 6th century, and the Near Eastern Iron Age took place in two phases during the 12th and 13th century. Asia began using iron at the same time as Europe, and China used iron long before the Common Era. In North and South America, the development of iron began right after the rock age, skipping the Bronze Age. During the early Iron Age, iron was used to make tools when combined with 0.3% to 1.2% by weight of carbon to form the alloy steel. Iron was used to make houses, tools such as swords, daggers, chisels, and knives, and jewellery, among others.

Early uses of the element include jewelry, weapons, and tools. The element was first used around 9000 b.c.e. and was found in northern Iraq. Copper was first used by Native Americans around 2500 b.c.e. One of the first skills that the ancient coppersmith must have learned how to do was shape the metal, possibly by heating. This element was first used to its full potential when Coppersmiths began to use tin with copper to make an alloy called bronze. An alloy is a mixture of two or more metals with properties differs from those of the individual metal. The alloy was first discovered as early as 4000 b.c.e. Bronze was used similar to copper due to the many variety of tools, weapons, and jewelry that are created from the alloy. It differs from copper in the way that with tin added, the alloy is a better conductor and easier to shape than the metal alone. Copper was used as the primary metal of the world to around 3000 b.c.e when society discovered iron. Many copper compounds are used in today’s agricultural, medical, and pest-control jobs. Copper Acetate (Cu20 (C2H3O2) 2) is a

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed.

These people made a discovery that made most everything we know today possible. They made the discovery of iron purification. Iron is a fairly common element on earth. we can mine it deep form within the earth's crust, but it can be found in mountains and in caves, it can even be found on the surface and in our water. The problem is that it is very hard to find it pure. Many times you can find it as iron oxide or as an ore mixed with other metals and rocks. The Hittites experimented and were able to separate iron from the impurities that were in it. Iron's melting point is about 2800 degrees Fahrenheit (onlinemetals). The Hittites were able to create furnaces to achieve this temperature and bring forth a weapon that no other group of people had ever seen before. Iron is an amazing pure element, it has higher toughness and tensile strength than copper or bronze, which gave the Hittites great advantages in weapons and armor. This knowledge soon spread though. It spread to Egypt and then the Bantu speaking people became very proficient at making iron.
