Cl2O but the two is a little two after Cl
Answer:
Molar mass of BaSO4 = 137.3 + 32 + (16 ×4)
= 137.3 + 32 +64
= 233.3g/mol
Molar mass = mass/ number of moles
= 233.3 g/mol = mass/ 1 mol
mass = 233.3g
Hope this helps.
As aluminium loses 12 moles of electrons oxygen gain 12 moles of electrons.
Explanation
4Al + 3 O2→ Al2O3
first write the ions of Aluminium and oxygen
that is, Aluminium ion is = Al^3+
oxygen ion is = O^2-
therefore one atom of Al loses 3 electrons moles while
one atom of O gain 2 electrons moles
from equation above there a total of number of Al atom are 4 =( 1 x4=4) atoms while
Oxygen atoms are 6= ( 3 x2=6) atoms
therefore the total number of Moles of Al lost is = 3 x 4 = 12 moles of electrons
total number of moles of O gained = 2 x6 = 12 moles of electrons
