Answer:
Electron
Explanation:
An Electron is a negatively charged particle.
A Proton is a positivley charged particle.
A Neutron has no charge (neutral).
- Acids are substances that form H^+ ions when dissolved in water.
- Bases are substances that form OH^- ions when dissolved in water.
- Substances with a Low pH ( < 7) have more H^+ ions are classified as Acids.
- Substances with a Higher pH ( > 7) have more OH^- ions and are classified as Bases.
The pH of a solution/substance is a measure of the molar concentration of hydrogen ions in solution/substance and as such, is a measure of the Acidity or Basicity of the solution/substance.
The letters pH stands for " Power of Hydrogen." and the:
Numerical Value: is defined as the Negative Base 10 Logarithm of the Molar Concentration of Hydrogen Ions.
pH = log10[ H^+]

A metal reactions form the molecules
Sodium Oxide ---> Na2O
Calcium Chloride ---> CaCl2
Potassium Sulfide ---> K2S.
I hope this helps! :)
The balanced chemical reaction is:
HC2H3O2<span> (aq) +Ba(OH)2 (aq) --> H2O (l) +Ba(C2H3O2)2
</span>
We are given the amount of HC2H3O2 to be used in the reaction. We use this amount as the starting point of our calculations.
0.432 mol HC2H3O2 ( 1 mol Ba(OH)2 / 1 mol HC2H3O2 ) = 0.432 mol Ba(OH)2 needed
Hope this answers the question.
