Rutherford's Experiment Lab Report

terms of molar concentrations, water at 25°C contains 1 x10-7 moles per liter of hydrogen ions and the same concentration

During the early 1940’s atomic science had just began to mature. Many people were exploring the powerful mystery of the atom. Two of those people were Eugene Booth and John Dunning, who, in 1941, synthesized uranium-235. Immense scientific growth followed their contribution, since it allowed for nuclear fission (Griffith). In the years following this discovery, nuclear science took a turn. Once only used as a constructive power source, atoms began being explored for their destructive power. In 1942 the United States government funded the Manhattan Project that sole goal was to develop a nuclear bomb. The initiator for this endeavor was surprisingly the famous scientist Albert Einstein. He wrote to Franklin D. Roosevelt , and tipped him off

Ernest Rutherford is often ascribed as the greatest and most respectable experimental scientist, second to none. His unparalleled success is attributed to his revolutionary work regarding but not limited to the atom. Rutherford's ingenuity and dexterity was able to alter our insight of nature three remarkable times. He first set laws on radioactive decay, explaining it as the spontaneous disintegration of atoms. He then riveted the scientific community when he determined the structure of the atom.

Where would the science world be today if it wasn't for Ernest Rutherford? We would probably still think that the atom was indivisible and unchangeable, or even there is no such thing as a proton. Ernest Rutherford is a famous physicist known for coining some basic terms in the field of physics such as; alpha rays, beta rays, gamma rays, the proton, the neutron, and half-life. He worked among the side of other great physicists like J.J. Thomson, Niels Bohr, Frederick Soddy, James Chadwick and Hans Geiger; together they discovered a whole new realm of science. (PBS, 1998).

In this equation shown above, our trial three our molarity ended up as 0.63716014 M and our molality ended up being 8.18627m.

The weight of oxygen is 16 grams and water is 18 grams [reference list]. 18 grams can be called a mole. A mole can be a substance [i.e. water] that would contain a number of molecules and that number is 6.02x1023[reference list]. This number is very well known as the Avogadro’s number; named after Amado Avogadro an Italian physicist.

From the start of time men and women have expanded on the theory of matter and atoms. Going from Leucippus and Democritus to Ernest Rutherford the theory has expanded on influences of others experiments. It started before Jesus Christ was born. The structure of the atom and the atom has changed over a long period of time.

Amount of water lost, by dividing the mass of the water lost during heating, by the number of grams per mole in 1 mole of water: 0.0565mol

After getting the total mass of the compound, divide it by the given mass which is 11.2 grams and express the answer as moles.

The purpose is to be able to combine Magnesium and Hydrochloride Acid and be able to deter the amount of hydrogen moles released from this double replacement lab ( A+BC->B+AC). The amount of Hydrogen can be found by using many different Gas Laws. Dalton’s law, one of the gas laws, states that the pressure of a combination of gas is the sum of all the particles in the container/area. Dalton’s law must be used because a volume of gas can be affected by temperature and pressure. In this lab, when collecting a volume over gas some water particles would change the pressure of the gas, therefore daltons law must be used. Volume, temperature, and pressure are all related. When

The first part of calculations was finding molarity, which has formula is, molarity equals moles divided by liters. We already were given the number of moles for HCl. Our results goes as follows: first trial is the molarity for HCl is 10, second is 9.9, third is 9.8, and fourth is 9.8. Then we proceeded to the second part of the calculations. The second part is where we figure out the molarity of NaOH, using the formula of MaVa=

In this case, Hydrogen has 3 atoms present and there is only 1 atom present in nitrogen. 3. Multiply each element by the number of atoms present. N- 14.01 x 1 = 14.01 H- 1.01 x 3 = 3.03 4. Now, you can get the molar mass by adding each element's product. 14.01 + 3.03 = 17.04 5.

If mass or gaseous volume of one of the reactants or products in a chemical reaction is known, mole(s) or mass or gaseous volume of a reactant or product can be calculated involving the mole ratio of a chemical equation.

calculate the molar mass of a given substance by summing up the atomic masses and then multiplying or dividing this sum by the coefficient of the substance in the chemical equation (BouJaoude and Barakat, 2000),

Named after Italian chemist, Amedeo Avogadro, in 1911, Avogadro’s number (denoted by NA ), also referred to as Avogadro’s constant, is a number of units in one mole of any substance. A mole of anything contains 6.02 x 1023 particles. These particles can be atoms, molecules, ions, formula units depending on the nature of the substance. Carbon has been used to define mole. The number of atoms (carbon 12) includes in 0.012 kilogram of carbon 12, which means that carbon 12 has an exact molar mass of 12 grams per mole; or 12 grams of carbon contains exactly 6.02 x 1023 atoms.
