Predict whether a precipitation reaction will occur when aqueous solutions of the following substances are mixed:
(a) $\mathrm{NaOH} + \mathrm{HCIO}_{4} \quad\quad$ (b) $\mathrm{FeCl}_{2}+\mathrm{KOH}$
(c) $\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}+\mathrm{NiCl}_{2} \quad$ (d) $\mathrm{CH}_{3} \mathrm{CO}_{2} \mathrm{Na}+\mathrm{HCl}$

Here we are looking to determine the product of our reaction. So the first example we have an age 42 s 04 those eight queers B A and our 32 acquis generates B A s 04 that is the solid state Add to an age four and oh, three. That is equally so. You can see our precipitate this b a s 04 In the next example, we have the following reaction each to us and the equi estate ad n I s 04 Also, Equus will give us an I ask. This is a solid state at H two s, 04 That is, of course, a queer. So you can see our perceptive is an I s twin part c. We have the following reaction. We have f e c l three that is acquis at three n a o h again acquis gives us f e oh h three that is solid at three and a c l. That is Aquarius. So you can see the precipitate because of the state that is f o h. Three

Turns of this question, we need to first to calculate the amount of culprit call right to need. It needed to be reacted. So the how many, most off the most off copper call Reid equals two 95. Appointed for Millie two times times it's molar mass. General 0.2102 Most per litter on dhe according to these ballots, too comical. You caution. We can see the we can see the ratio off so they enforce it on on the copper chloride is to over three. So based on this, we can calculate the most off off sodium force if it were divided that with the smaller mess will with this my clarity Well, you know, we need a 31.37 point one miles.

Hello. Okay. The question is calculate the majority of so did my drug side. And the question. Okay so we will used in this question mold racial concept. So what is given in the question In the question we have volume of sodium hydroxide. That is 12 to 28.85 mm. If we can avert it into leader then we will divide 5000 That will come out 0.0 Who's 885 later. Okay. And the mass of oxalic as they were That is given zero 506 Grand molar mass of oxalic acid. That is the 90 grandpa removed. Okay. Okay. Yeah it will do 90 grand by the move. If we calculate Mall of H two City go for then how can we calculate we know that more equal to mas bye Mueller mas. Okay so moss has given 0.506. Get out And mother masses given 90 ground for more that will equal to 5.62 into 10. To the power minus three minus three more. Okay now what is the situation between oxalic acid and sorry and hydroxide situation is X two C two or four plus any which that gives any edge C two or four plasma has to do here we can conclude that one mole of oxalic acid required one mole of sodium hydroxide. So we can write this mole of any which will be equal to mold of any edge moon of obviously like festival. Okay, what is the formula of mole and modularity? We know that more equal to moderate into volume or moss by muller moss. Okay, so in that question we have majority and volume of sodium hydroxide. So here we will put majority in the volume of what? sodium hydroxide And we have mole of sodium. We have moral of oxalic acid. That is the total 5.62 Into 10 raised to the Power -3. So where is the volume of any which? That is 0.0 mm. Double left five letter equal to 5.6 to 10 to 10 to the power minus three more. Okay, when we solve it then we will get 1 94 .8 into 10 to the power -3 mall are lifted. Or we can Right this 0.194 Moon foreign leader Soria hydroxide. So it is the correct answer of this question. Okay.

Everyone. My name is in this question we have to solve. Which is the 1st 1 is Ah. So do you mind group sign which he has a B o h is equal as stated here, five e our exist with the solution off Magnesium. Mmm. Could dry, which is concentration is open toe 18 more clarity. Uh, in this question, he told us amount off. So do my dark side. Makes it is 75 million liter isn't. Mix it with amount off my ignition cry. 100 25 millilitres. A question here is amount. We mix it with these amount. Is there a press ity for me? First off the answer. Jeez, what happened with these? Reacted together. Busy forming magnesium hydroxide and for sodium chloride, sodium chloride. Is this solvent? While magnetism on group site is a compound the half K s B Z one toe boy. 06 times fighting negative. 13. So I don't know if this prosecutor form it or not. We all know this is a magnesium on Brooke sign. We deserve a small amount of silver and the other remain. And among the desert is it's, um It's convert to magnesium blast to last. To which negative And we know right this case is B. It's represent a concentration off magnesium blast, too. Times vice a concentration off. It's you get there, which is negative power to this is how can radic a speed. So now we want to know is this amount. We mix it together to form a precipitate it or not to answer Jerry's. We first said the concentration off H negative in this solution is but a prison. Its initial concentration, which means the B. 00 H, is 2.58 the concentration off, which is still in negative 2.58 and the initial volume is 75. As it's stated here, why the concentration of which is the total volume is 75 plus 1 to 5. So this is the concentration off. It so may mean easier cooler rights on here. So magnesium corn rye is represents amount off magnesium so we can stay that the concentration off magnesium blast, too, is equal. The concentration initial off magnesium chloride, which is opening toe a one a times of my 102 5 divided by the toe, tell voiding so This is a concentration off magnesium plus two. So now we can calculate value. It's cute, is similar to the law off K S B. But using disease concentration which is a concentration off magnesium times vice a concentration off. Ohh, negative power too. So then we compare the results. Cue boys. A K is big by some we found is a phone using a calculator. We found that the queue is higher Sense of value of kiss piece that we stated here. So that's mean the precip t will be for me. Thank you.
