sashaice [31]3 years ago
5 0

Isolated atom basically means atom which exists separatly without any bonding with other atoms. It can only be acheived experimentaly because normally all atoms are bonded together by strong nuclear forces and its really hard to isolate a single atom.

Indicate the mechanistic symbol (SN1, SN2) that is most consistent with the following statement. Select the single best answer.
Degger [83]

Answer:

The most consistent mechanism is SN1.

Explanation:

The solvolysis of tert-butyl iodide in methanol will arise by the SN1  mechanism.

The reason for that is due the geometric structure of tert-butyl. The tertiary structure allows the formation of a stable carbocation, after the loss of the iodide ion. The carbocation will then be attacked by methanol molecules forming an eter.

Please help me!!!!!!!!!!!!!

1)The limiting reactant will be aluminum acetate

2) The mass of aluminum hydroxide formed will be 9.75 grams.

<h3>Stoichiometric problem</h3>

The equation of the reaction is as below:

Al(C_2H_3O_2)_3 + 3NaOH --- > 3C_2H_3NaO_2 + Al(OH)_3

The mole ratio of the 2 reactants is 1:3.

Mole of 100 mL. 1.25 mol/L Al(C_2H_3O_2)_3 = 0.1 x 1.25 = 0.125 mol

Mole of 300 mL, 2.30 mol/L NaOH = 0.3 x 2.3 = 0.69 mol

Thus, aluminum acetate is limited.

Mole ratio of  Al(C_2H_3O_2)_3 and Al(OH)_3 = 1:1

Equivalent mole of Al(OH)_3 = 0.125 mol

Mass of 0.125 mole Al(OH)_3 = 0.125 x 78 = 9.75 grams.
