To obtain number of atoms, multiply number of moles by the number of molecules per mole (Avogadro's number) and by the number of atoms per <u>molecule </u>(<u>in this case, there are six if you count them in CH3OH</u>). Therefore, 1.44 x 10^25 atoms in 128 grams of CH3OH.
I hope this helps and please mark brainlyest i need 5 to level up
I believe its Nitrogen and Carbon...?
H2Se is the acid as it is donating H+ to H2O and forming SeH- (which is conjugate base).
H2O is the base since it’s receiving H+ from H2Se to form H3O+ (which is the conjugate acid)
Se is in the same group as O but is in different period which means Se has higher radius compred to O. this led to H-O bond being stronger than H-Se bond and H-Se bond which in turn makes it easier for H2Se to donate H to H2O
