I don't want to write an essay but thank you so much for your clear and awesome videos. People like you that want to help and can do it so well are such a blessing. Thank you again, you are what every teacher should be like.
Of course; I can't tell you how much I appreciate you & your videos. If your students complain about you remind them you've got 25K people who'd love to have you as their teacher !!
These videos are extremely helpful. I wish I could ask you some questions. I am back in chemistry after only taking it in high school more than 30 years ago. I am taking a class online, and it is very difficult to understand with just the textbook. Your videos make the material more understandable. I also really enjoy that you show the physical reactions. Thanks!
+Ruchelle B, great question, oxygen needs two electrons to fill its outer shell and each hydrogen has one to give, so it take two hydrogens to satisfy each oxygen.
There are really not rules for the transition metals. The transition metal can form different charges so you have to designate the charge in the name, like iron (III) oxide. In this case iron would have a +3 charge. You can look up the most common charges.
Kelly Osada No that does not work because it does not show the correct structure and Ca is +2. The molecule actually looks something like this OH-Ca-OH. The OH (-1 charge) is the hydroxide and that is why it is called calcium hydroxide. You wrote it more like an acid, H in front. Does that help?

How did you know that iron had a +3 charge in the first example? Should the charge be provided in cases where elements can yield more than one charge, or is it a certain circumstance for synthesis reactions?
Thank you so much, I'm a high school student taking Honors Chemistry. These videos will help me get the grade I want on the test for the chapter tomorrow.
The test went very well, the best grade I have received on a chemistry test all year. I will be sure to check out your other videos for chapters coming up thank you again.
If it is an ionic compound then use the common charges directly from the periodic table. For example group 1 elements are always +1 and groups 17 are always -1. If it is covalent then you have use the Lewis structure rules.
+Muhja Ismail Sorry no magic, it is a little bit more complicated but there are some general rules. Check out this website, www.chemteam.info/Equations/Synthesis.html Also….you can see a listing of all my videos at my website, www.stepbystepscience.com
How would you determine the charge of a transition metal when it is not specified? For example, Cu + Fe. The charges aren't specified so I'm not sure how you would go about predicting the products
If it is bonded to something then you can do it that way. For example, Fe2O3; oxygen is -2 and there are three of them that equals a total charge of the oxygen of -6. That means the total charge of the iron is also -6 but there are only 2 of them. Therefore the charge on each Fe must be +3. Does that help?
@@stepbystepscience I understand that but in a reaction where the transition metal isn't bonded to anything, like Cu + Ag(NO3), how would you know the charge of copper? Would you just go with the most common ion?
So, I ended up here because I failed a quiz over this today, and I just want to say thank you! I finally understand : ) Also, do you know how to tell which reactants and products are gases, liquids, solids, or aqueous? We had to do that also on the quiz, and I'm pretty sure it's why I failed :'(
Maybe you are expected to use or know the solubility table/rules. Glad that you find the vidoes helpful. You can see a listing of all my videos at my website, www.stepbystepscience.com
Great question James Arellano , the most common charges for iron are 2+ or 3+. In the video I did say, "iron has a 3+ charge in this case". I probably could have put more emphasis on this statement, but that is why it is 3+ in this problem.
Can you tell me why you place the 2 in front of the Ag instead of putting a subscript 2 beside the Cl like it is on the other side? Sorry, I'm very new to chemistry.
Great question…..It shows that there are 2 separate atoms of the element silver as opposed to 1 molecule that it made up of 2 atoms of silver atoms. You may not think so but there is a big difference. Thanks for watching.
+LovezYouful Good questions, Iron generally occurs as +2 or +3. I just decided in this case that it would be +3. This would be called iron (III) oxide. But it could also be make it iron (II) oxide then the equation would just be FeO.
Ruchelle Bay I know this is very late, but this might help other people too. The reason is because Hydrogen has a +1 charge, while Oxygen has a -2 charge. Therefore the crossover rule comes into play, so it becomes H2O. The -2 charge crosses over from oxygen and goes to Hydrogen, while the +1 Charge from Hydrogen crosses over to Oxygen. Hope this helps!
+Pamela Coronado Great that your understanding has increased. Thank you very much for the positive comment. You can see a listing of all my videos at my website, www.stepbystepscience.com
what would you do if you had 2 negative charges? how would you balance that and make it neutral. I have a question like that and it makes no sense to me.
You know the charge on the iron based on what it is bonded to. For example, FeCl3 would mean iron is +3 because chlorine is always -1 and there are three of them. Does that help?
Thank you for the great videos, you explain everything so well and you also make it fun to watch and learn. All the videos help me a lot you are a great teacher!
When you write the A + B it does not matter which element goes first, but when you write AB then it does matter. The metal goes first. For example Na + Cl -> NaCl (Na, sodium is a metal) . It is also ok to write Cl + Na -> NaCl, but you may not write Na + Cl -> ClNa. Does that answer your question?
The metal, in this case Mg, comes first in the formula, non metals second. And then because MG has a +1 charge and O has a -2 charge it takes 2 Mg to balance out the 1 O. Does that help? You can see a listing of all my videos at my website, www.stepbystepscience.com
+Good Bad Because Good questions, chlorine (Cl) is a diatomic gas. In nature it always occurs as Cl2. The other diatomic gases are: Br, I N, Cl, H, O and F. You can remember them as Brincl Hof (pronounced Brinkle Hof), a persons name.
If i wanted to synthesize 5 amino 1mq at home from it's parent compound , 1 methyl quinolinium, what would need? Could you provide step by step instructions? What substances in nature contain the parent compound? Are there any substances found in nature that contain 5 amino 1 mq? Thank you in advance!
I am not sure what you are referring to but in a bond chlorine will gain one electron to fill its outer shell. In doing so it will then have a charge of negative one. Also chlorine is really missing an electron...a chlorine atom has a neutral charge. Does that help?
Pink Skittles When balancing chemical equations you can only add whole number coefficients. Coefficients are the numbers in front of the chemical formulas. After adding the 2 in front of the Ag there are 2 of each element on both sides of the equation and it is balanced.
Richard Reed If you actually mean "drawing" no I have not, if you mean "writing" I did do some videos with a Wacom (sp?) pad thing but then I have to worry about whether I am writing correctly/neatly enough. I am a bit limited by just using Keynote but it seems to work out most of the time.
If someone could respond quickly it would be very helpful to me, at 3:02 the first problem, why does iron have a charge of 3? I thought it was a transitional metal so it didn’t have a charge
Transition metal do have charges. It is just that many of them can have two or three different charges. Iron is most commonly +2 or +3, in this problem I just decided it would be +3. Does that help?
can i just take a moment to say a massive thank you for explaining to me what my chemistry teacher refuses to

I cant understand
How did you know that iron had a +3 charge in the first example? Should the charge be provided in cases where elements can yield more than one charge, or is it a certain circumstance for synthesis reactions?
i think it is because the common charge of iron is 3 or the +3 charge makes the net charge zero when combined
u can chck on ur periodic table
I'm confused too with that part because iron is a transition metal and therefore its charge is variable it could be 4 as well.
That's why I don't understand the Chemist. If only I understood that.
still helpful 7 years later! thanks so much :)
Physics doesn't change much over the years.
These are great videos. A plus for anyone trying to understand chemical reactions. Thank you for sharing.

do have to write the solubility too right? and also if its a metal and non metal it would be ionic and ionic compounds are always solid?
There is a solubility table you can look at.
