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 ...
In this question we have to use the equation Moles= Mass(g)/ Mr. We have the mass of PbO2 so to find the moles we need to divide the mass, which is 37.2g, by Its Mr, which is 207.2 + (162) = 239.2. th...
