at 1:50 would you take into account the big numbers that are apparent before the formula in some different equations? example - 2Fe + 3CO2 ??? would you just do normal co2 relative formula mass or times it by 3?

not my scinece teacher teaching us the complete wrong thing and it saying products instead of recatants in the equation. idk if there are two ways to do it but i think the way shes taught it will just calculate how much of the products are useful instead of how much recatant creates a useful product. thank god i watched this because that test in two days would not have gone well
It doesn't matter, no matter is created nor destroyed in the reaction, so the total mass of the products is the same as the total mass of all the reactants. Your science teacher knows what they are doing!
thanks to u i got 9 9 9 in triple science!!!! literally all thanks to u all i did was watch ur videos and do pmt questions i love you sir
woah nice
please drop the method

Same here man
@@account8494practice papers, cognito videos. Just before the exam watch one of the Science Shorts videos eg ‘All Chemistry Paper 1 in 30 Minutes’.
Super helpful, you make it really easy to understand and very straightforward. Thank you!
one of the most underrated channels💔
hey can you do a video of productive revision
Thank you so much sir 💗❤🎉
at 1:50 would you take into account the big numbers that are apparent before the formula in some different equations?

That’s also what I was wondering
Thanks
I'm a few years late but you would include the big numbers as it is the total formula mass
hello.. why some reference dividing it with the sum of all products? What is the difference?
No difference in a balanced equation as both sides total relative atomic mass should be the same

The equation for the production of ammonia is incorrectly balanced
It should be
N2+3H2=2NH2
@@SirGallyoN2 + 3H2 = 2NH3
does this cover foundation??
yea
mr bateson
is very very cool
indeed
@@ethanralph3374 I agree
Litreally did this yesterday lol
what is the position of the equilibrium - 4:35
under there
3:08 isnt the reaction reversible so some of the ammonia would turn back into reactant?
👍🏽👍🏽👍🏽
At 3.16 the equation is not balanced
ok
1:00
economy?!?!?! realy?!?!?

nice
