Classify each chemical reaction as a synthesis, decomposition, single-displacement, or double-displacement reaction. (a)\mathrm{CaSO}_{4}(g) \longrightarrow \mathrm{CaO}(s)+\mathrm{SO}_{3}(g) (b) $2 \mathrm{Na}(s)+\mathrm{O}_{2}(g) \longrightarrow \mathrm{Na}_{2} \mathrm{O}_{2}(s)$ (c) $\mathrm{Pb}(s)+2 \mathrm{AgNO}_{3}(a q) \longrightarrow \mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}(a q)+2 \mathrm{Ag}(s)$ (d) $\operatorname{HI}(a q)+\mathrm{NaOH}(a q) \longrightarrow \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{NaI}(a q)$

Let's classify each chemical reaction as synthesis, decomposition, single displacement or double displacement for eight. We have a double displacement chemical reaction for B. We have a synthesis chemical reaction for C. We have a single displacement chemical reaction, and for D, we have a decomposition chemical reaction.

Hi everyone. So classify each chemical reaction. Is the synthesis become positions in your displacement or double displacement reaction. So, okay, these calcium salvage, use calcium oxide and sultry. So uh No, it is a decomposition reaction. It is yeah. The composition. Yeah. The reaction invade a single reactant. You're stupid at that. Is calls himself pictures heating use calcium oxide. And I saw three. Yes. Okay then. Second one toys in S plus or to use any tool to as the sodium peroxide. So it is a combination or synthesis reaction. Yeah, synthesis uh combination reaction. Right. The next PVS plush toy section or three acquires gives PB and or three toys plush toys SCS. So in this case the lorries displaced by letter three pigs displacement. Single displacement reaction. Single. This placement. Yeah reaction. Mhm. Then they were H. I. Aquarius lasting marriage because water and any I. So yeah. A chinese a seal. An eighties base. So it is double displacement or a choice. I see. An energy is best. So it is double displacement reaction, arm utilization or receive best reaction. It is double displacement. Mhm. Yeah. Let's bless me. The ancient are I see best actually face our neutralization reaction. Mhm. Mhm. No trucks liberalisation reaction. Yeah. Yeah. Thanks a lot.

So in the many types of chemical reactions, there is very, very common one school displacement reactions there to type of displacement reactions. The 1st 1 is called a single displacement. Also call a replacement. So what happens in this place in the reactions is an element is replacing another element of displacing it in a single displacement. Only one thing gets changed in a double replacement with is the second time two things get this place there two types of single displacement reaction. You have the 1st 1 in which you have a metal and then I can come bone for by metal and nonmetal. So this will be the middle. This will be the nonmetal and then the metal This metal will displays this medal so you have a C plus B, right? The other type of single displacement issue have a plus B c, and you would get if this a nonmetal and B C will look the same. The nonmetal will replace the nominal. So you get be a plus C. Since we have two types of medical this eight and I'm gonna call this be an example off a in which the thing that you served by itself will be a metal. So we have potassium plus lithium bromide and the metals going to replace the metal or this place that is gonna give you potassium brew might and lithium for be an example. That would be, for example, if you had chlorine plus sodium II, it will give you sodium chloride, and I died or iodine by itself, right? I mean, analysis tribute to here, and they should be up to here. So chlorine gas plus sodium iodide will give you sort of chloride and iodine. Note is that the nominal replace the nonmetal kicked out. This happens to have a two year in this. Don't because this college ins are the atomic means that when the by themselves, that you have a little too so no double displacement reactions of a general equation O a. B I on a company with a different Anna Campo where this is the medal, this is the nonmetal. And then this is a different metal and the different nonmetal and is gonna give you new compounds, right? So be 80 metal nominal plus C b. I don't not metal. That's what a normal double read this place man looks like so an example of it would be, for example, potassium bromine plus Leave him cool, right? Right. This is a B and C D. So we do A which will be potassium and the which will wreak lowering plus c would you relieve him and B which will be roaming. And that would be a double displacement, right? Two things get switch and then another example. Another, more complex example. You would have cause of hydroxide plus magnesium nitrite, right. It helps to label things. This will be a being C d. We give you a D plus c three and then we do it so it will be cost. Um, the will be nitrogen See will be magnesium and be will be Hi drops a and then we have to the charges when you're doing double displacing the reaction causing with the charge of plus C nitrogen has a charge of negative three. So will be a three here and now to hear when you cross your charges to make in any component and then for my niece of oxide, my museum has a charge of plus two hydroxide has a charge of minus one so cross charges. So too, goes there. That one goes there and then, you know, we have our com poems, and then I always issue bones your equations, which that one's a little more complex, and then you would have your chemical equations. So that is a double displacement reaction. That is also a simple level displacement reaction and those who are single displacement of reactions.

So in this question they asked that is classified each chemical reaction is synthesis decomposition. Single displacement audible displacement reaction. So first one is K. Two years plus seven or three days. We get 10 or three plus series. If you see properly there is a yeah A replacement of S Sunday and all three takes place and their sway that is mhm. You know from possession sell for is displaced and from kobol night it is displaced and that so it is a double displacement reaction did you say? Yeah. Buddy displacement very action reaction since hitting walls and once displacement of this place meant of brian's. Okay. Do I ins that is sulfide IBM's nitrates. Yeah. Yeah I am. So this display double displacement here then No second Try such too pleasant to use twice and H. three. Yes. So there is a combination combination are synthesis a reaction in reach average two or more er to engage and to and it's too yeah the reacts with each other. Mm. Okay. Mhm. You place. Mhm. The Prius. Okay. I don't know. Ammonia. Mhm. Uh huh. Ammonia like by roberson cases but. Mhm. To close ammonia. So yeah a single product single product and the process is called however synthesis but but it's nice it's called hamburgers synthesis. Yes. The next. Yeah. See one. Mm. But it's serena's plus your social to acquire skills and torrential to acquiesce plus C. O. S. It is single displacement reaction. Single displacement which now reaction since it it was ones displacement of this placement of chlorine from cobalt. Sure cobalt to sink. Then next ch three B. Our guests you will get decomposed to CS three plus B. R. Gas. So you know this is a decomposition reaction B composition. The action invades. Oh and Wales. The telegram manage. Come on meantime damage what they split age. His split days into. Mhm. Uh huh. Nick island roaming mean tied and brought me
