Here we are balancing are some chemical equations. So this is where we have the same number and type of atoms on the left hand side, as we do on the right hand side. So fastly we have two and a at two That yields NH 202. Following on from this, we've got P four add 5 to. That's an equilibrium with P 4010 as our products. Following on from this, you've got CAHC- 032 at N A. To C 03 sodium carbonate. That's an equilibrium with CACO. three, calcium carbonate, had to lots of N A H C 03. And so an extra we have is following well and H three at 5- five moles of oxygen. That's an equilibrium with four moles of nitrogen monoxide at six H 20. And so our final example is to an A two H 20. That's an equilibrium of two, lots of N H O H two moles of sodium hydroxide and H two

We're given the situation that we have iron metal makes with sodium phosphate, and we have to determine where did this? Ah, reaction. Okay, it's whistle for when we look at this. Ah, we have a medal. And also very far. Hey, Constitution off off another. Um, I want a compound. Now. There may be a single displacement, but we don't really know. Okay, we can first assume we have a single this space with reaction for Use them. We can have. Ah, Are you mixed with sodium phosphate? And then we were half hour are in four states are soon to be former iron flee. Um, are you So I am phosphate. And also we have sodium mad. Oh, Okay. So by looking at this reaction, um, I don't think it's likely to happen. It's not likely to happen. The reason is that for sodium medal or an equal one meadow, they are extremely reactive, extremely reactive. So therefore, if okay, I assume this reaction happened, this highly reactive species is going to wee africa iron phosphate, and then you ever actually go back to our react and go back to our reaction. So you know, the in other words sodium phosphate. It's already of every stable and iron yourself. You're so strong enough to, uh, to go through this reaction to pull these sodium are in, so therefore, we don't have any reaction.

So this question is about the right name and formulas off some compound. So for party that is CR or three. So this is known as chromium six oxide. Because here oxidation state of chrome amis les six because off oxygen is minus two. So we get this. So for Barbie, that is what I she um What? I she, um magnet, but I should mention it. So production magnet is nothing but production magnet. So this is the year toe. I am an awful So this is what I shall magnet apart. See, chromium carbon, That is chromium garbling. Goldman Cardboard, that is CIA seal six. Body of the question that is the a C R. Toe. 47 So this is an honest, very, um, like remit bid M day. Good on me for body that is Lenten. Um, so then numb three sell food. Lenten, um, three soul food. No, no hydrate. No, no, I would rate So this is our l. A s 04 Try start nine edge toe. So this is no, No. Hydrate is used for the nine water model and three is the oxidation. State off. Lengthen on inventing. Um three Lenton himself. So no part of off the ocean is That is you see entry 0.3 h 20 So this is no less gold. So in court three cyanide Are you hydrated? Pray I read. Go to three water molecule and observation straight off Golden plus three for this case. So this is our answer. So this is our so I books the answer. So this is what I am Magnate for third chromium Carbonell. So this is chromium Carbonell? No, Forties billion Dyke Remit. So this is very, um die plummet. Next, lengthen. Um Morneau Hydrate Lenton. Um three. Some perfect Lenten amply sulfites. No nitrates. Next. Is he called, please Cyanide right here today. So I read the answer in the green box for these formulas.

Here in this problem, The H -3 year watched, replacing the right, replacing the bromide first replacing the bromide. I am at the end, I am at the and jane to form chain to form actual CH two whole 4 C. O. Reg, which reacts. But then intra molecular charity in the presence of a seat in the present, all issued to form psychotic six psychotic six remembered is structured electron. So according to the option in this problem, option B. It correct.
