Magnesium 2+ ions bind to (they don’t REALLY bind) and stabilize ATP molecules. The ATP (also ADP and AMP) contain highly reactive phosphates (the energy is stored in the chemical bonds between the phosph...

In this model ions are considered perfect spheres and therfore point charges. In this model ions have only electrostatic attraction with no covalent interactions.

Hydrogen bromide and hydrogen chloride are both simple molecules. They have London forces between molecules. It is essential that you highlight that these interactions (induced dipole-dipole) are BETWEEN ...

Mass Spectrometry is often used by scientists to determine all the isotopes present in a sample (using their isotopic masses) and thus identify the element. The first stage is called the 'ionisation sta...

Initially it helps to read over the question a couple of times underlining/ highlighting all important information ie. volumes and concentrations. Next it always helps to have a chemical equation to work ...
