A compound contains 22.1% Al, 25.4% P, and 52.4% O. What is the empirical formula of this compound?
In this day and age where energy is one of the greatest factors in world events, it is unsurprising to see nuclear energy, the bridge between fossil fuels and renewable resources, argued for and against so fiercely. Yet under this umbrella term of “nuclear energy” that people enjoy throwing around, there are two wildly different forms of energy. Things that perhaps shouldn’t be lumped together so haphazardly. Those are Nuclear Fission and Nuclear Fusion.
Many people do not realize that chemistry is a part of our day to day lives. One specific thing we see on a daily basis is the colors and paint people use in paintings, on buildings, and any other place paint could be. When this paint is developed, the people who make it have to decide exactly what the compound should be made up of. This is an important thing to consider when making these paints because as discussed in Chemistry 101 lab, compounds are different things that develop one item, in this case it is paint. They have to make sure that the paint is homogenous because if it was heterogeneous when being applied, the paint would not go on well. The creators of the paint discuss the different ways to make sure the compound is homogenous,
The actual score on the exam was as little bit higher than what I predicted. This is due to the fact that I worked really hard to earn this grade and I liked the material a lot more. I implemented new strategies and used old strategies that had worked in order to try and get a higher grade.
To analyze and determine if a chemical reaction occurred between two compounds using the concepts we learned in class. Also, if the chemical reaction occurred, to determine if it formed a precipitate or gas.
The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
What are atoms? Well, atoms are the base of any chemical element. Atoms consist of in multiple things, in which these things scientists of the past have discovered, and they are so well known, poems and stories are made about them. In fact, the Periodic Table of Elements is made up of atoms. Atoms are the smallest bit of matter. They are matter and matter is them.
The purpose of this experiment was to prepare an unknown Grignard reagent and then identify the product by molecular weight and melting point. An IR reading was taken to further identify and validate what product was formed.
Intermolecular Forces: Are forces between molecules. Depending on its strength, they can cause the formation of three physical states: solid, liquid and gas.
The mole’s three identities include formula, molar mass or mole mass. This is defined as the mass of one mole or 6.02 * 1023 particles of that substance expressed in amu’s.
Atoms are the basic building blocks for everything we see in our lives today. Atoms combine, share, lose and gain electrons to become molecules. A molecule is a group of two or more atoms that are held and formed together by chemical bonds. Covalent bonds happens when there is
NaClO does not have any covalent bonds because it mostly happens to atoms which have their outer shell filled and this case NaClO does not. SClO_2 does have covalent bonds because its outer shell is full and it holds its atom together. The two different types of covalent bonds are
How can someone explain the relationship between a chemical engineer and his job? It’s pure chemistry! Chemical engineers work with chemicals to develop new products. They may engineer a more efficient source of fuel. When engineering this, they would calculate emissions that are released when the fuel is used. Chemical engineers go through a lot of schooling and training, have high salaries, can find jobs all over the country, and their job has both benefits and downfalls.
Pop culture can do more than just properly educate people about science. Pop culture helps to contour a lot of the public's knowledge of science and the people behind science. It can be more of an influence, a greater tool, and leave a better lasting memory. It can be greater than any book could ever even attempt to. You have sci-fi movies like Star Wars the no biophysics class can compete with. You have movies where they make monsters come to life with lighting from the sky. This can be a kid’s first experience of science (Riper, 2003). This would be their first messages about science. The some people can likely base their knowledge on these movies. Science is compound and can be hard to grasp the concept. Popular culture can have a big role in how the public can portray it.
Key unit competence: Describe how properties of ionic compounds and metals are related to the nature of their bonding
