The ideal gas equation is given by pV = nRT, where p is pressure of the gas, V = volume, n = molar amount, T = temperature (in Kelvin!) and R is the gas constant which is given by 8.31 J / (K*mol). From t...

Protons have a +1 charge and electrons have a -1 charge. The overall charge on an atom is 0, therefore there must be an equal number of protons and electrons in an atom so that the charges cancel out. So ...

1. Identify a common denominator4(x +1)/12 + 3(2x + 5)/12 (= 2)2. Expand both brackets(4x + 4)/12 + (6x +15)/12 = 23. Multiply out the denominator4x + 4 + 6...

The dual nature of light. Sometimes it behaves as a particle, sometimes as a wave.

You take the power of X down and multiply the term by it. Then you reduce the power of the term in X by 1.
