... Frequency (f) is defined as the number of cycles per second, and is expressed as sec-1 or Hertz (Hz). Frequency is directly proportional to energy (High frequency =High energy) and can be express as: E =hf Where E is energy, h is Planck's constant and f is frequency. Planck's constant: h= 6.62607 x ...

6-3 Solving Systems by Elimination
... Since -2y and 2y have opposite coefficients, you can eliminate the y by adding the two equations. The result is one equation that has only one variable: 6x = -18. When you use the elimination method to solve a system of linear equations, align all like terms in the equations. Then determine whether ...

... became ions. This is the result of a transfer of electrons. In the above reaction, an electron is transferred from a sodium atom to a chlorine atom. The sodium atoms now have ten electrons, instead of eleven. This means that the sodium has one more proton than electron and has a charge of +1. The c ...
