In the molecular equation for a reaction, all of the reactants and products are represented as neutral molecules (even soluble ionic compounds and strong acids). In the complete ionic equation, soluble ionic compounds and strong acids are rewritten as dissociated ions. In the net ionic equation, any ions that do not participate in the reaction (called spectator ions) are excluded. As a result, the net ionic equation shows only the species that are actually involved in the chemical reaction. View more lessons or practice this subject at www.khanacademy.org/science/a...

@@netcald991 Many textbooks are that expensive. It's easy to imagine, and if you go to college, you'll likely need to buy such books. A harsh reality that will hopefully change by then, but definitely true. They really do cost that much, if not more, especially if you're buying them new.

How do i figure out what is aq and what is not? Ive balanced an equation to 2NaOH + CuSO4 -> Na2SO4 + Cu(OH)2 But now I need to write a net ionic equation but I cant figure out how to determine spectators without knowing its solubility

@abdullahali6280 6 лет назад

What do you do if no solid can be formed? Or is that not possible?

@_elommusk 5 лет назад

If there's no solid, I believe you still only do the molecular equation and complete ionic equation, but no net ionic equation.

Why did u not split the 2 at the end of the equation

@RedLtdGuitar 5 лет назад

If you mean why he didn't split the AgCl, my understanding is that it forms into a precipitate (hence the (s) for solid) and therefore, you don't write it as individual ions. But, the sodium nitrate is still in an aqueous state and therefore, you write those two things as Na^+(aq) + No3^-(aq). Someone correct me if I'm wrong!

I'm stuck on how you know if the element has a positive or a negative

@puddleduck1405 2 года назад

metals form positive ions, non metals form negative ions. If it's in group 1 of the periodic table it forms 1+ ions, if it's in group 2, it forms 2+ ions, group 3 is 3+, group 5 is 3-, group 6 is 2-, and group 7 is 1-. The transition metals are slightly different cos they can form multiple ions, but the question should tell u using Roman numerals, eg Fe(II) forms 2+, and Fe(III) forms 3+, hope this helped :)

@josesparky2188 5 лет назад

In my experience, Kahn academy has only every made things long and complicated. After years of being forced to watch their videos, and deciding their methods were just not for me, a teacher assigned this video saying it made everything make sense. It made more sense before I was in chemistry at this point. No thanks Kahn academy.
