• ## Atomic Mass Of Beanium Lab

In this Beanium lab, the objective was to make sense of the numbers used to calculate average atomic mass. By separating, counting, and weighing beans we were able to create the numbers used to calculate the weight of one bean. From there, we could use the total number of beans to produce the percent abundance for each type of bean. These were the numbers that we had to produce in order to understand how and why there are many types of isotopes for each element. In doing this lab, we can think through the importance of finding the average atomic mass and not just using a single isotope for an element. 1. A weighted average must be used to calculate the average atomic mass of Beanium because, unlike a real element on the periodic table, the…

• ## Mass Destruction And Long-Term Effects Of The Atomic Bombs

office and was informed of the Manhattan project’s success; America now had the first atomic bombs. While American soldiers and civilians were weary from four years of war, the Japanese military was unwilling to give up their fight. This left President Truman with as he said, “The most difficult decision of my life.” On August 6, 1945, the first atomic bomb, named ‘Little Boy’, was dropped on Hiroshima, Japan. Three days later ‘Fat Man’ devastated the city of Nagasaki, Japan. Shortly after…

• ## Difference Between Atomic Mass And Molar Mass Of A Compound

Atomic mass: the mass of an atom of a chemical element expressed in atomic mass units; approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes Molar mass: a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance Mole: the amount of a substance contained in 6.02 x 10²³ particles of that substance…

• ## The Differences Of Mendeleev And Modern Periodic Tables

Newlands arranged the elements in order of atomic mass where every eight elements has similar properties. He called the relationship “the law of octaves”. Even so, this law could not be applied for the elements beyond Calcium, so it was not accepted by the scientific community. The modern periodic table is thought to be the outermost ground-state electron configuration of the elements. The elements are divided into categories; the representative elements, noble gases, the transition elements…

• ## Carl Friedrich Gauss And The CGS Framework

The CGS framework retreats to a proposition in 1832 by the German mathematician Carl Friedrich Gauss to base an arrangement of supreme units on the three essential units of length, mass and time. Gauss picked the units of millimeter, milligram and second The centimetre–gram–second arrangement of units (truncated CGS or cgs) is a variation of the metric framework taking into account the centimeter as the unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS…

• ## Pros And Cons Of Potential Energy

Energy is the ability to work, more, or elicit change in matter. Energy cannot be formed or impaired; it’s always preserved. Potential energy is a kind of spared energy that objects have because of their position or configuration. Energy comes in many forms, and can be converted from one form to another. Kinetic energy is energy of mass in motion, and the formula is E=1/2mv^2. The most important property of kinetic energy in the ability to do work, and it can be transferred from one body to…

• ## Engineering Stress And Strain Case Study Answers

Polytetrafluoroethylene (PTFE)? Please provide a graphical answer. Answer # 15: The repeating unit of PTFE is –CF2-CF2. 16) A vacancy in a lattice puts the surrounding bonds lattice in tension or compression? Answer # 16: Interstitial atoms cause the lattice to be strained, or put into compression around the interstitial. 17) What is the difference between inter diffusion and self-diffusion? Answer # 17: Inter diffusion: Inter diffusion takes place when atoms change…

• ## Copper Atom Research Paper

comprise an atom. The first of these components that make up an atom is the proton. The proton is a very important part of an atom, because the atomic number of an atom is equivalent to the number of protons that that atom has. Additionally, the mass of an atom is equal to the sum of the number of protons and the number of neutrons of that atom. The number of electrons that an atom has is also equal to the number of protons that that atom has.…
