Answer:
With an understanding of the ideal gas laws, it is now possible to apply these principles to chemical stoichiometry problems. For example, zinc metal and hydrochloric acid (hydrogen chloride dissolved in water) react to form zinc (II) chloride and hydrogen gas according to the equation shown below:
2 HCl (aq) + Zn (s) → ZnCl2 (aq) + H2 (g)
Explanation:
Explanation:
As a neutral lithium atom contains 3 protons and its elemental charge is given as . Hence, we will calculate its number of moles as follows.
Moles =
=
= 100 mol
According to mole concept, there are atoms present in 1 mole. So, in 100 mol we will calculate the number of atoms as follows.
No. of atoms =
= atoms
Since, it is given that charge on 1 atom is as follows.
=
Therefore, charge present on atoms will be calculated as follows.
Thus, we can conclude that a positive charge of is in 0.7 kg of lithium.
