Answer:

<h3>Which of the following is the correct definition for electronegativity</h3>

<h3>А. The amount of energy to attract or bond electrons</h3>
Answer:
Explanation:
The modern model recognizes particles in the atom, whereas Dalton's model does not.
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:

The mole ratio of the 2 reactants is 1:3.
Mole of 100 mL. 1.25 mol/L
= 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
and
= 1:1
Equivalent mole of
= 0.125 mol
Mass of 0.125 mole
= 0.125 x 78 = 9.75 grams.
