How many milliliters of 0.550 m hydriodic acid are needed to react with 5.00 ml of 0.217 m csoh? hi(aq) + csoh(aq) → csi(aq) + h
Harman [31]

First calculate the moles of CsOH.

moles CsOH = 0.217 M * 0.005 L = 0.001085 mol

 

We need 1 mole of HI per 1 mole of CsOH, therefore the moles of HI needed is:

moles HI = 0.001085 mol

 

The volume required is therefore:

Volume = 0.001085 mol / 0.550 M

<span>Volume = 1.97x10^-3 L = 1.97 mL</span>

When a solution of NaI reacts with a solution of AgNO3, what is the net ionic equation?
Leni [432]

Answer:

Ag⁺(aq) + I⁻(aq) → AgI(s)

Explanation:

Net ionic equation is a way to write a chemical equation in which you are listing only the species that are participating in the reaction.

In the reaction:

AgNO₃(aq) + NaI(aq) → AgI(s) + NaNO₃(aq).

The ionic equation is:

Ag⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + I⁻(aq) → AgI(s) + Na⁺(aq) + NO₃⁻(aq).

Now, listing only the species that are participating in the reaction:

<h3>Ag⁺(aq) + I⁻(aq) → AgI(s)</h3>
