Could someone confirm that this is correct? Thanks!

Explanation:
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
Atomic mass of aluminum = 27 g/mol
Molar mass of oxygen gas = 32 g/mol
Molar mass of aluminium oxide = 102 g/mol
Total mass on the reactant side :
Total mass on the product side :
Total mass on the reactant side = Total mass on the product side.

Hello!
You would expect to observe 2 triplets in the ¹H NMR spectra for o-chlorotoluene.
Multiplicity observed in ¹H NMR spectra when the atom couples with a neighbor ¹H atom. The multiplicity is equal to N+1 where N is the number of neighbor atoms.
To observe a triplet, you'll need a molecule with 2 neighbor atoms. In o-chlorotoluene (shown in the figure), only protons C and D have 2 neighbor atoms (B and D; A and C, respectively), so you'll expect to see a 2 triplets.
Have a nice day!

2x = 350- x
3x = 350
x = 350/x
therefore,
x = 116.67cm.
so, (350 - x)cm³ = (350- 166.67)cm³ = 233.33cm³
Hence distance covered by gas A is 116.67cm that by B is 233.33cm
