Neutral water<span> has the same concentration of Hydrogen ions which are also called the H+ and the Hydroxide ions, which also could be referred to as OH-. A neutral water is considered to have a pH level of 7 wherein it stands between the acid level and the base level which makes it suitable for human consumption.</span>
Since the mass of a single popcorn kernel is not given, lets us assume that it is 1 gram
Now:
1 mole of popcorn kernels contain kernels
Since:
1 kernel weighs 1 gram
Then,
kernels would weigh grams
To remove one electron from singly ionized helium, will require approximately 54.4 eV or 8.72 1020 J of energy.
The amount of energy required by an isolated, gaseous molecule in the electronic state of the ground to absorb in order to discharge an electron and produce a cation has been known as the ionization energy. The amount of energy required for every atom in a mole to drop one electron is most often given as kJ/mol.
Anything that causes electrically neutral atoms and molecules to gain or lose electrons in order to become electrically charged atoms as well as molecules .
Therefore, the "To remove one electron from singly ionized helium, will require approximately 54.4 eV or 8.72 1020 J of energy."
