What are the resulting spectator ions when aqueous solutions of rb2o and cacl2 are added together?

Explanation:

Spectator ions are the ions that do not take part of the reaction and, so, you do not show them in the net ionic equation.

1) Molecular equation:

You must show the phases

You are told both Rb₂O and CaCl₂ are in aqueous solutions, so you know their phases and you can write their ionization equations.

2) Ionization

       RbCl(aq) → Rb⁺ (aq) + Cl⁻ (aq)

3) Total ionic equation:

Now you can write the ionic equation:

2Rb⁺(aq) + O⁻ (aq) + Ca²⁺ (aq) + 2Cl⁻ (aq) → CaO(s) + 2Rb⁺(aq) + 2Cl⁻(aq)

4) Net ionic equation:

Cancel the ions that appear in the same form in the reactant and product sides:

So, you canceled 2Rb⁺ and 2Cl⁻ because they are the spectator ions.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
