Write a balanced equation for each of the following neutralization reactions: (a) Potassium hydroxide solution is added to phosphoric acid. (b) Strontium hydroxide solution is added to acetic acid.

Start by balancing our equation. We have the neutralization of city acid. Yeah we're barium hydroxide. Yeah. This would produce water and barium acetate. Mhm. You got to balance this. Put it to here in the two here because there is our balanced occlusion and we put our faces in here Equus liquid. A quiz. And how many moles of barium hydroxide are needed To neutralize? .461 moles acetic acid. We use our reaction. Start geometry here two moles of the acetic acid To one mole of barium hydroxide. And this would give us point 231 moles barium hydroxide. So this would be the amount needed for neutralization. Yeah.

This question we've been asked to write the chemical equation of a reaction between ascetic acid and calcium component. So looking at ascetic acid is chemical formula is CH3 c. O. H. And this is an aqueous solution. This will be reacting with calcium carbonate, whose chemical formula is C. A C. or three. And this is going to be a solid. So when these two are here, what is going to form here is calcium asserted Chemical Formula C. AC. H. three, see or or two. And this will be an actor solution Plus H 20. Which is a little now coming. Looking at this reaction, we can tell that this is not a balanced chemical equation Because for example, here we have CH3, c. o. two of these. But here we only have one of. So looking at this, if we have a true here and then we count the number of carbon atoms, hydrogen atoms and oxygen atoms in the products and then the reactions, they are now equal of meaning to say this is now a fully balanced chemical reaction.

For auction, eh? Acidic acid undergoes compassion in the ear. The products form will be carbon die Excite along with water represented by the reaction. The given reaction here is unbalanced. So there are two atoms off carbon for out number off hydrogen towards the left, only two carbonara only one carbon along with two hydrogen on the right. So we balanced them by placing a two in front off carbon dioxide and water. This makes six oxygen atoms on the right by four on the left. So we place two in the front off or two to balance the whole chemical equation for part B. When solid cash, um hydroxide is heated, it gets decomposed into solid Cadman along with border people. Reaction can be presented us God meme hydroxide. Ben. He did. It gives cadmium oxide. Bless water for part C. When nickel metal combines with chlorine gas, it forms a solid nickel chloride. We have solid nickel plus flooring to it. Give us nickel chloride to Richard stolid in nature

Hi there. This would be question number 85 and we are asked to write and balance out some equations. So in letter A we have acetic acid, C H three C 00 H. More commonly known as vinegar, where the acid found in vinegar. So that is going to be Aquarius because the acid is dissolved in water and it is combusting, which means it combines with oxygen. It says it completely combusts. So the products of a complete combustion or carbon dioxide gas he had since it's hot, it is typically water vapor. Okay, so we need to balance this equation. If we look at the acetic acid, we see two carbons in that. So I'm going to put a two in front of CO two to balance out the carbons, I would see four hydrogen zone the acetic acid. So I'm going to put it to in front of H 20 because two times two gives me four. Now we need to balance the oxygen on the product side. There are two times two which is four plus two more oxygen. For a total of six. We see too in the acetic acid. So that means we need four more. So that would be a two in front of 02 Because two times two would give me for more oxygen and that is our balanced equation for part A in part B. We have calcium hydroxide decomposing, so calcium has a two plus charge. Hydroxide is the poly atomic ion with a one minus charge. So I would need two of those and this is a salad. It decomposes into calcium oxide two plus and two minus. So the formula is just Ceo we're told that is a solid and the other product is water vapor or H. 20 Yes. As we check for balancing now we see one calcium on each side of the equation. We see two oxygen's and we see two hydrogen. So when written correctly, this equation, he's already balanced. Let's look at letters C. And let us see we have nickel metal reacting with chlorine. Gas, chlorine is a die atomics with Cl two. All right. And we are making nickel chloride. So we're going to say it's the nickel with a plus one charge, I'm sorry. Plus to charge because that is going to give us and I C. L two nickel chloride, which would be a solid. Alright, looking at this equation, it is balanced. There's one nickel and to Gloria's on both sides of the equation so it is complete. Okay, Thanks so much for joining me for this question. Yeah.
