Question

For the following Chemical Reaction : 2HBr(aq)+BaOH2(aq)-->2H2O(l)BaBr2(aq) .. write the ionice equation, including phases.

Answer 1

The ionic equation for the reaction between hydrogen bromide and barium hydroxide includes writing down the balanced chemical equation, breaking up the soluble compounds into their ions to form the complete ionic equation, and then canceling out the spectator ions to obtain the net ionic equation which shows the actual chemical change.

Step-by-step explanation:

The student is asking for the ionic equation for the reaction between hydrogen bromide and barium hydroxide. First, let's write down the balanced chemical equation:

2HBr(aq) + Ba(OH)2(aq) → 2H2O(l) + BaBr2(aq)

Now, let's write the complete ionic equation:

2H+(aq) + 2Br−(aq) + Ba2+(aq) + 2OH−(aq) → 2H2O(l) + Ba2+(aq) + 2Br−(aq)

Next, we cancel the spectator ions to get the net ionic equation:

2H+(aq) + 2OH−(aq) → 2H2O(l)

This net ionic equation shows the actual chemical change during the reaction.

Answer 2

Step 1)
write out all aqueous compounds as ions
2H+ (aq) + 2Br- (aq) + Ba2+ (aq) + 2OH- (aq) --> 2H2O (l) + Ba2+ (aq) + 2Br- (aq)

Step 2)
Cross out the spectator ions (ions that appear on both sides of the reaction) 2H+ (aq) + 2OH- (aq) --> 2H2O (l)
what you have left is the net ionic equation.
I hope this helped.
