Answer:
Molar mass (M) = mass(m) / number of moles (n)
To find the mass of Al2O3 first calculate it's molar mass
thus
M(Al2O3) = (27×2) + (16 × 3)
= 54 + 48
= 102g/mol
Mass of Al2O3 = molar mass × number of moles
= 102 × 0.513
= 52.326g of Al2O3

Answer:
Sample A - mixture
Sample B- Mixture
Explanation:
Looking at sample A, we can see that as water was poured over sample A, the sample was separated into its components as the powder disappeared leaving behind a gritty black sand-like material on the surface of the paper. A separation of the mixture has taken place.
In sample B, we can clearly see that it is a mixture because the amount of solid recovered is much less than the total mass of the solid put into the beaker. The sample must have been separated into its components.
Answer:
Linear molecule is a molecule in which atoms are deployed in a straight line (under 180° angle). Molecules with an linear electron pair geometries have sp hybridization at the central atom. An example of linear electron pair and molecular geometry are carbon dioxide (O=C=O) and beryllium hydride BeH2.
Explanation:
The solutions are the following :
12. C
13. A.
