How many ions are there in two moles of water?
If the dissociation equation is:2 H2O-------------(H3O)+ + (OH)-the number of ions is 12,044281714.10e23.
In a chemical equation can you count the number of molecules?
Only if you know how many moles there are.
What is the coefficient shows in a chemical equation?
The coefficient represents the number of atoms, molecules, ions, or moles of a substance.
What is the purpose of a subscript in a chemical equation?
A subscript indicates the number of atoms or ions of an element in a chemical formula.
Which equation best represents the dissociation of water molecule into hydrogen ions and hydroxide ions?
The equation is: H2O------>H+ + OH-
How is a net ionic equation written from a complete ionic equation?
By removing from the complete equation any ions that occur in the same number on both sides of the complete equation.

Only if you know how many moles there are.
How do you identify the number of terms in an equation?
Carry out all the multiplications and divisions and then count them.
Can the total ionic equation shows the net change in the equation after spectator ions been removed?
The total ionic equation shows all of the equation, even the spectator ions. The net ionic equation shows the net change after spectator ions have been removed.

What is a constituent ion?
Constituent Ions are Spectator Ions. Spectator Ions are ions that appear on both sides of the chemical equation. (Spectator Ions appear as both reactants and as products). They do not participate in the reaction and they are NOT shown in the Net Ionic Equation.
