To count the number of ions in a equation you will use a net ionic equation. To start with a net ionic equation start with a balanced equation, and break all soluble strong electrolytes.

In a chemical equation can you count the number of molecules?
Only if you know how many moles there are.
Which equation best represents the dissociation of water molecule into hydrogen ions and hydroxide ions?
The equation is: H2O------>H+ + OH-
Ions that appear on both sides of a chemical equation are?
Ions that appear on both sides of the equation are spectator ions. These ions do not participate in the reaction at all. Thus, they are omitted when writing the net ionic formula of a reaction.
Which ions are not spectator ions in the precipitation equation Pb(NO3)2 plus 2KI -- and gt PbI2 and nbsp plus 2KNO3?
The spectator ions in this precipitation equation are K+ and NO3-. The non-spectator ions are Pb2+ and I-. They combine to form the precipitate PbI2.
What is the balanced equation of c2h60?
do you have another chemical equation with this as the answer could be 2CH30 my advice is to count the number of atoms and make sure they match if they do it is a balenced equation. If you have to write one yourself then make sure the numbers match.
In a chemical equation can you count the number of molecules?
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 number should be placed in front of CaSO4 to give the same total number of sulfate ions on each side of the equation?
To balance the number of sulfate ions on each side of the equation, a coefficient of 3 should be placed in front of CaSO4. This will give a total of 3 sulfate ions on each side of the equation.
Which equation best represents the dissociation of the water molecules into hydrogen ions and hydroxide ions?
The equation is: H2O------>H+ + OH-

The unit used for counting umbers of atoms ions or molcules is the?
You generally count them in moles, which is actually a number: 6.02X1023.
Ions that appear on both sides of a chemical equation are?
Ions that appear on both sides of the equation are spectator ions. These ions do not participate in the reaction at all. Thus, they are omitted when writing the net ionic formula of a reaction.
What is a complete ionic equation?
An equation showing all dissolved compounds as ions
How is a net ionic equation from a complete ionic equation?
the spectator ions are removed
How is a net ionic equation written from a ionic equation?
the spectator ions are removed
Is NaCl acidic or alkaline and give a chemical equation to support your answer?
In solution the number of chloride ions (negative) equals the number of positive ions (sodium). NaCl -> Na+ + Cl- which is neutral in totality (neither acid nor alkaline)
