The first step is to stop rubbing the area and clean the area with a cloth saturated with mineral spirits. The second step is to buff the shoe by applying the mineral spirits to the area with a soft cloth and buffing the shoe. This will remove the scratches.
Step one is to use a grit-less sandpaper to gently sand the area of the shoe where the scratches are. Step two is to use a toothbrush and hydrogen peroxide to clean away any debris that is left behind. Step three is to apply a layer of leather conditioner to the area of the shoe that was scratched.
The amount of energy required to ionize a hydrogen atom is equal to 13.60 eV or 13.60 times the energy needed to ionize a hydrogen atom in its ground state. The ground state of a hydrogen atom is when it has the lowest energy and is neutral.
You can ship a car to Ireland via a number of different shipping companies. At the time of writing, the cost of shipping a car from the US to Ireland, including all import duties and taxes, was roughly 4,600 euros.
The amount of energy required to ionize a hydrogen atom depends on the energy level of the electron. As the energy level increases, so does the ionization energy. The amount of energy required to ionize a hydrogen atom in its fourth excited state is 74.2 kilojoules per mole.
