In this question we've been given incomplete chemical reactions and we've been asked to complete them and then write the net ionic equation.
00:08
So the first one we've been given hcl -3 plus barium hydroxide and this forms bacl -o3 plus h -2o.
00:22
So to balance this out we need two moles here and here this is two.
00:28
So this is now completely balanced.
00:29
So remember we need to form the ionic equation and the compounds that actually form ions in solution are the ones whose state are acous.
00:40
So this is a liquid.
00:42
So these are the compounds whose ions we need to first or fall from.
00:45
So you're forming two moles of h plus ions, two moles of c -o -3 ions plus barium 2 plus ions, plus 2 moles of hydroxide ions.
00:58
And then in the products we are forming two or rather barium two plus ions and two moles of clo3 plus h2o.
01:08
The next step would be to remove the spectator ions this time around.
01:12
This is going to be the clo3 minus ions, the glue and the barium ions.
01:21
Remember, the spectator ions are those ions that will be common in both the reactants and the reactants and the products...
