A South African Englishman doing his 3rd Year thanks you kindly

[@xancrystal3115]

in part b where we calculate the moles of MgCl2 she forgot to multiply the Mr of chlorine by 2 cuz there are 2 atoms of chlorine

[@mansithawani2571]

Amiiiiiiiiiiiii!!!!!!!!!!

[@mattharris1930]

the formula given in part b is the wrong formula for ethanol, the one in part a is the correct one. (if I'm wrong then even when there's only one product formed the A.E. is not =100%)

[@thefightingdog3032]

they're the same formula but part a needed to be balanced so has a 2 in front of the formula and part b didn't need to be balanced, its all to do with ratios of the elements

How to improve atom economy of a reaction?

[@aliagha7826]

get a hybrid car, hope this helps.

How to know the desired product

[@NA-so1ke]

it will give it to you in the question

[@sarahmohammed80]

the equation is wrong? atom economy = (molecular mass of desired product/sum of molecular masses of all REACTANTS) x100.... its masses of all reactants, not the product

[@hannalewicka6598]

no, it's just the products. it wouldn't make sense if it were all reactants because you want to see how much of ALL PRODUCTS is useful.

[@sarahmohammed80]

Hanna Lewicka check the syllabus

[@hannalewicka6598]

Oliver its the MR of the products that you create

[@Oliver-wm1xi]

@@hannalewicka6598 Thank you, that is what I thought but this video is massively misleading. She even uses a majuscule 'M' to show Mr when M actually means molarity.

[@hannalewicka6598]

Oliver no probs :)

[@Ayesha______]

She slows down here and it’s appreciated

What will be for two step reactions

[@_chukzyy2251]

Thank you for the video it really helped😁😁

[@chemistrylearner2096]

amazing

[@zigzagnemesist5074]

one of the easier topics of A level chemistry in my opinion. I think this should be part of the gcse syllabus as well

[@superman2957]

It is mate...
