Answer:
0.20 moles of Pb(CH3COO)4
Explanation:
89g Pb(CH3COO)4 x 1 mol Pb(CH3COO)4 / 443.376 g Pb(CH3COO)4
= 0.20 moles of Pb(CH3COO)4
Moles of Sulfuric acid- H₂SO₄ needed to react completely : 3.2 moles
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction(balanced)
<em>2LiOH + H₂SO₄ → Li₂SO₄ + 2H₂O</em>
From the reaction equation above, the reaction coefficient shows the mole ratio of reagents and products
moles of Lithium hydroxide-LiOH = 6.4 moles
mol ratio of LiOH : H₂SO₄ = 2 : 1, so mol H₂SO₄ :

Hello! So to answer your question all the answers can be found within the above chart provided. Simply compare and contrast the pH levels in which the indicators changed color.
So doing that we can conclude the followoing pertaining to our indicators. Bromothymol blue 5.3-7.3
Methyl yellow 2.4-4.3
Bromocresol green 3.3-5.3
Red cabbage extract 3.3-5.3
For your second question it is the exact same concept, but we can just look at our answer for the first question to conclude which indicator would be best used for those ph levels.
Comparing and contrasting we can see that the best indicator to use for observing PH changes around pH= 2 would be Methyl yellow,
for around pH=4 would be Bromocrescol green,
and for pH= 6 it would be Bromothymol blue.
If you have any other questions or would like further explanation just let me know! :)
