First we need to rearrange so that it's all on one side of the equals sign:x² + 2x - 48 = 0 Now we have to find what will sum to make the coefficient of x (2) and multiplies together to get -48...

The Van der Waals force is the weakest of all the intermolecular forces. This interaction occurs between every molecule, over very small distances, and becomes weaker the further away the two molecules ar...

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...
