Gina's group classified their mineral samples based on relative hardness. They considered the minerals that have a hardness of l

ess than five as relatively soft, and those with a hardness of five or above as relatively hard. They showed their groupings in a table.
A 2 column table with 3 rows. The first column is labeled Relatively soft minerals with entries: Bornite, Chalcopyrite, Goethite. Second column is labeled Relatively hard minerals with entries: Hematite, Pyrite, Pyrrhotite.

What does Gina’s group need to do to correct the information in the table?

Bornite needs to be switched with pyrite.
Pyrite needs to be switched with goethite.
Goethite needs to be switched with pyrrhotite.
Pyrrhotite needs to be switched with hematit

11. Write the balanced equation for the reaction of HC2H3O2 with Al(OH)3 to form H2O and AI(C2H3O2)3
TiliK225 [7]

Answer:

3HC2H3O2(aq) + Al(OH)3(aq) --> AI(C2H3O2)3(aq) + 3H2O(l)

Explanation:

HC2H3O2 is the chemical formula for Ethanoic acid which can be written as CH3COOH.

Hence, the balanced equation is stated as 3CH3COOH(aq) + Al(OH)3(aq) --> AI(CH3COO)3(aq) + 3H2O(l)

Acid + base → Salt + Water.

The equation is a neutralization reaction in which the acid, aqeous CH3COOH reacts completely with an appropriate amount of base, aqueous Al(OH)3 to produce salt, aqueous AI(CH3COO)3(aq)

and water, liquid H2O only.

During this reaction, the hydrogen ion, H+, from the Ethanoic acid is neutralized by the hydroxide ion, OH-, from the Aluminum hydroxide to form the water molecule, H2O and aluminium ethanoate.

Thus, it is called a neutralization reaction.
