An alpha particle is a helium nucleus without the electrons - 2 neutrons and 2 protons.
So, all you would have to do is 2 x 55, which equals 110.
Answer and Explanation:
The balanced chemical equations are as follows:
The chemical formula of oxalic is 
In the case when oxalic acts reacted with the water so here the oxalic acid eliminates one proton that leads to the development of mono acids
After that, the second step derives that when oxalic acid is in aqueous solution eliminates other proton so it represent the polyprotic acid
Now the chemical equations are as follows:
Elimination of one proton

Now the elimination of other proton

Ionization energy is the energy required to remove the
outermost electron from one mole of gaseous atom to produce 1 mole of gaseous
in to produce a charge of 1. The greater the ionization energy, the greater is
the chance f the electron to be removed from the nucleus. In this casse, Radium
has the largest ionization energy.
Neon is an element and elements are pure oxygen is. Or it is a gas
well none its made from iron nut i would go with c. a solution sorry if im wrong tell me in comments
