Chemistry how to get the equation for energy of electron

In oxygenic photosynthesis water is the electron donor and, since its hydrolysis releases oxygen, the equation for this process is: 2n CO2 + 4n H2O + photons ? 2(CH2O)n + 2n O2 + 2n H2O. carbon dioxide + water + light energy ? carbohydrate + oxygen + water.

You must try different combinations of coefficients such that the number of atoms of each type is the same on both sides of the arrow.
Start with N. You have two atoms on the left, so you must have a total of two N on the right. or 2NH_3. By doing so you get 2*3=6 atoms of Hydrogen on the right. But to get 6 H on the right you must have 3H2 (6 atoms H on the left).
The balanced equation must be
N_2+3H_2---->2NH_3

Chemistry - is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned with the composition, behavior (or reaction), structure, and properties of matter, as well as the changes it undergoes during chemical reactions.

- It is a physical science which studies various substances, atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, and which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes.

A unit of energy used for convenience in atomic systems. Specifically, it is the change in energy of an electron, or of any particle having a charge numerically equal to that of an electron, when it is moved through a difference of potential of 1 mks volt. Its value (in mks units) is obtained from the equation W = qV, where W is energy in joules, q the charge in coulombs, and V the potential difference in volts. For a potential difference of 1 volt and the electronic charge of 1.602 × 10?19 coulomb, the electronvolt is 1.602 × 10?19 joule. See also Electron; Ionization potential.

Conversion factors:

• 1 eV = 1.602176487(40)×10?19 J (the conversion factor is numerically equal to the elementary charge expressed in coulombs).

The kinetic energy gained by an electron by falling through a potential difference of 1 volt. 1 eV is equivalent to 1.6 × 10-12 ergs. 1,000 eV is referred to as 1 kilo electron volt, or keV, and 1,000,000 eV are referred to as 1 mega electron volt, or MeV.

From this equation W = qV = (5 x 1.6 × 10?19 Coulomb) x 8900 v = 44.500 x 1.6 × 10?19 Joule
= 44.500 eV (because 1 eV = 1.602176487(40)×10?19 J)
= 44.500 x 10?6 MeV ( because 1 MeV = 1.000.000 eV)
K.E. = 0.0445 MeV

Well, I hope this right, I'm not so sure my self :P.
Hope this help and be kind to rate please, thanks.

Faraday's Law is actually more accurately referred to as the plural of that, Faraday's LawS.
The reason for this plurality is indicated by the existence of three different laws or equations, as shown below:

• Faraday's Law of Induction - related to principles of transformers, inductors, electric motors, generators
• The Maxwell-Faraday Equation - states that a changing magnetic field creates an electric field in a closed loop, or circuit; appears in a modern set of Maxwell's Equations, and is commonly called "The Faraday Law."
• Faraday's Laws of Electrolysis - refers to the relationships between change in mass of substances (at electrodes) and amount of electricity (Coulombs) flowing through an electrolytic cell.

I know that the last one listed above is taught in the second semester of general chemistry courses offered at community colleges. The first two, and maybe the last one, are taught in physics courses.

The full chemical equation for photosynthesis is:

Glucose + Oxygen = Carbon Dioxide + Water + Energy
C6H12O6 + 6O2 = 6CO2 + 6H2O +Energy

chemistry diagram...???? give me the equations, let me try...

Hi,
The law of conservation of mass and energy states that mass and energy can neighther be created nor destroyed however it can be changed into one form to another.

Protons have a +1 charge. This is the same magnitude of an electron but an electron has a −1 charge. Neutrons have a 0 or no charge.

The following Wiki Article explains the process of Proton decay

Main article: Proton decay Protons are observed to be stable and their theoretical minimum half-life is 1036 years. Grand unified theories generally predict that proton decay should take place, although experiments so far have only resulted in a lower limit of 1035 years for the proton's lifetime. In other words, proton decay has never been witnessed and the experimental lower bound on the mean proton lifetime (2.1×1029 years) is put by the Sudbury Neutrino Observatory.[5]

However, protons are known to transform into neutrons through the process of electron capture. "When a high energy-proton collides with an atom, it causes the ejection of an electron from the outer layer of the atom."[6]:125 This process does not occur spontaneously but only when energy is supplied. The equation is:
where
p is a proton, e is an electron, n is a neutron, and νe is an electron neutrino The process is reversible: neutrons can convert back to protons through beta decay, a common form of radioactive decay. In fact, a free neutron decays this way with a mean lifetime of about 15 minutes.
