This video looks at how to identify the five reaction types presented in most introductory chemistry texts: 1. combination/synthesis, 2. decomposition, 3. combustion (& hydrocarbon combustion), 4. single replacement, 5. double replacement. Each reaction type is presented with an identifying feature specific to the type, and several examples are included, also touching on product prediction. Product prediction videos are linked at the end. For help with balancing equations, see this video • Balancing Chemical Equ... , for help with stoichiometry, see this video • Stoichiometry Tutorial... .

I'm am still very confused. Why does Cl have a subscript of 3 on the right but a subscription of 2 on the left
@CrashChemistryAcademy
@CrashChemistryAcademy 3 года назад
the subscript changes to balance the charge. The Zn on the left has a 2+ charge while the Al on the right has a 3+ charge. You may want to watch my video on predicting products, which goes into more detail with this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nUO6S2tmB8w.html

So if I combined copper nitrate solution and an Iron nail. Would it be a precipitation reaction?
@CrashChemistryAcademy
@CrashChemistryAcademy 4 года назад
Yes but... So solid copper metal precipitates from aqueous copper ions, which makes it a precipitate. However most high school textbooks would classify this only as a single replacement. However a college text would classify it as an oxidation reduction, with the observation that a precipitation occurs. It most definitely is an oxidation reduction as well as precipitation. You might want to take a look at my video on double replacement for clarification: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nUO6S2tmB8w.html

how am i supposed to find synthesis without the product because that's the only feature
@CrashChemistryAcademy
@CrashChemistryAcademy 3 года назад
If it is a reaction between a metal and a nonmetal then you write a compound that balances the ionic charges, and that is the synthesis. With two non-metals it is not straightforward at all and you would need a lot of additional information, and two metals create an alloy.

zinc sulfate solubility is 57.7 g/100 mL water, anhydrous (20 °C), magnesium fluoride is 0.013 g/100 mL (temp not given) (Wikipedia)

@CrashChemistryAcademy
@CrashChemistryAcademy 3 года назад
It has two names, it is usually called an acid-base reaction, but in higher level texts you may see it called a metathesis reaction, meaning not an oxidation reduction.

Can I ask something? Is CH4+H2O=CO2+H2O can be balanced?
@CrashChemistryAcademy
@CrashChemistryAcademy 3 года назад
That is not really a reaction. CH4 does not react with H2O. If you mean CH4 + O2 -> CO2 + H2O, that is a reaction that can be balanced. See ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Vym8RUqKhcw.html for how to balance.

Can you burn oxygen? I mean going from oxygen to ozone.
@CrashChemistryAcademy
@CrashChemistryAcademy 4 года назад
So while ozone is synthesized through oxidation, probably via diatomic oxygen, it likely does not release much energy (I have not compared their bond energies) since ozone is a better oxidizer than diatomic oxygen, in other words it loses an oxygen atom easily, meaning it probably has low bond energy and therefore there is little energy given off in bond formation, so no burning. Hope that makes sense.

@@CrashChemistryAcademy But does that mean one oxygen molecule gets oxidized but the other not, so reduced? That's confusing!
@CrashChemistryAcademy
@CrashChemistryAcademy 4 года назад
@@fukpoeslaw3613 Good point. I think one way to view this is that the ozone molecule has a slight polarity with the central oxygen being partially negative. From this, one might assume that the central oxygen gets reduced during O3 formation, with the added (third) oxygen getting oxidized. I'm not sure how else one could look at this. It does have to be a redox, nothing else fits.
