Answer:
40.72g of sulfuric acid are needed
Explanation:
When sulfuric acid, H₂SO₄, is neutralized by lead (IV) hydroxide, Pb(OH)₄, Lead (IV) sulfate, Pb(SO₄)₂ and water as follows:
2 H₂SO₄ + Pb(OH)₄ → Pb(SO₄)₂ + 4H₂O
To solve this question we must find the moles of 57.18g of Pb(SO₄)₂. As 2 moles of H₂SO₄ produce 1mol Pb(SO₄)₂ we can find the moles of H₂SO₄ and its mass as follows:
<em>Moles Pb(SO₄)₂ -Molar mass: 275.23 g/mol-</em>
57.18g * (1mol / 275.23g) = 0.2078 moles Pb(SO₄)₂
<em>Moles H₂SO₄:</em>
0.2078 moles Pb(SO₄)₂ * (2mol H₂SO₄ / 1mol Pb(SO₄)₂) = 0.4155 moles H₂SO₄
<em>Mass H₂SO₄ -Molar mass: 98g/mol-</em>
0.4155 moles H₂SO₄ * (98g / mol) =
<h3>40.72g of sulfuric acid are needed</h3>
Answer:
I think it is C since the trees hold the habitats of the animals and provide cover so with less animals there is less diversity.
Answer:
5.5 mol H2O
Explanation:
Given over what you need and then mole ratio of coefficients in the balanced equation then cross multiply and do PEMDAS for that, and then you got your answer :) hope this helped.
Sulphuric acid (H2SO2) is a dibasic acid. It generated H+ ions when dissolved in water. In order to neutralize an acid, a base containing hydroxy ion (OH-) will be required.
NaOH, Ca(OH)2, KOH, etc. can be used to neutralize H2SO4.
If NaOH is used as a base, following reaction is initiated.
2NaOH + H2SO4 → Na2SO4 + H2O

A horizontal exempted is a bit tight but I think it’s a good idea
