Okay therefore we're gonna write both molecular and that ionic equations. So because that this 1st 1 I have acetic acid and I'M reacting that through an aqueous systems of K. O. H. Therefore we're walking to do potassium acetate i m sorry is a chris and some water. Okay simply as a keep in mind this is a weak acid. So we're gonna leave it together. So once we create our network ionic equation that stays written the same. Hey this is gonna be a K. Plus and an O. H minus. This is walk to it is in a K. Plus and the acetate. So ns think you have the right to see the potassium ions or spectator ions. So we'll simply react this with O. H. Minus. And we're walk to create our acetate add to H 2 0. Liquid. For this reason there's her net ionic equation. Okay so now we're walking to take chromium 3 hydroxide i m sorry is a solid and we're walking to react it through nitric mountain Which will give us three waters part chromium three nitrate. We need the threes since we've obtained three minuses. For this reason we required three H add to is this is a strong acid. Therefore it's going to it is in HPE plus in nitrates. This is going to be chromium ion and also three nitrates. So ns think you have the right to see the nitrates space going to be Spectator ion so they'll disappear. For this reason our net ionic equation A strong acid division apart. So three h plus gives us our three waters and then just some chromium three ion. It s okay so in our final instance here we've got H. C. L. O. A systems of the being reacted through calcium hydroxide solution. Therefore we're gonna make some calcium hypochlorite and also we're also going to create some water. We should balance that v a pair of twos. Therefore this is a weak acid. Therefore we're gonna leave it together. This is a strong base therefore it'll get broken up. This is an Aquarius solution below so we're gonna have actually some calcium ion to hypo chlorides for this reason we have the right to see the calcium ions or spectator ions. The all at once equation will end up through there's going come be as well H. C. L. O. Remember we leave the together due to the fact that it's one Aquarius equipment plus The 20. H- is i m sorry will provide us the two hypochlorite ions and the two waters. So hopefully you deserve to see the we've gained a bunch that twos here so let's rewrite that correctly. Therefore H. C. L.

O. Near the wage minus will provide us hypochlorite and the water
