The percent composition of the neutral aluminium acetate - Al(C2H3O2)3 - is:
- C: 35,29 %
- O: 47,04 %
- H: 4,45 %
- Al: 13,23 %
The balanced equation is: 2Al(C2H3O2)3(aq) + 3(NH4)3PO4(aq) → AlPO4(s) + 6NH4C2H3O2(aq)
Aluminum is lighter in weight, has a higher shine, and does not tarnish like pewter. Pewter is darker in color, has a slightly duller appearance, and may develop a patina over time. A magnet can also help differentiate them, as aluminum is not magnetic while pewter may show some magnetic attraction due to its composition.
Sodium bromide has the chemical formula NaBr. Its molar mass is approximately 102.89 g/mol (22.99 g/mol for Na and 79.90 g/mol for Br). To find the percent composition, divide the molar mass of each element by the molar mass of the compound and multiply by 100. For sodium: (22.99 g/mol / 102.89 g/mol) * 100 ≈ 22.36%. For bromine: (79.90 g/mol / 102.89 g/mol) * 100 ≈ 77.64%. Therefore, the percent composition of sodium bromide is approximately 22.36% sodium and 77.64% bromine.
Aluminum can corrode under normal conditions, but the rate of corrosion can vary depending on factors such as exposure to moisture and other environmental factors. In general, it can take several years for aluminum to show signs of corrosion under normal conditions.
Ca+2 C2H3O2-1 <---- these are the ions and their charges Ca+2 C2H3O2-1 C2H3O2-1 <----- the charges have to add up to zero, so two -1 acetate ions cancel out one +2 calcium ion Ca(C2H3O2)2 <----- simplify
The balanced equation is: 2Al(C2H3O2)3(aq) + 3(NH4)3PO4(aq) → AlPO4(s) + 6NH4C2H3O2(aq)
Anodized aluminum itself is not magnetic because the anodization process forms a non-ferrous oxide layer on the surface. However, the base aluminum material can be magnetic depending on its alloy composition.
