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>

Consider the chemical reaction in equilibrium.
Zarrin [17]
This is an application of Le Chatlier's principle:  What happens when we add a reagent to one side of an equation? The reaction will shift to the other side.  So heat is a reactant and we're adding more of it, the reaction must therefore, shift to the right ( or the products side).

lianna [129]
The correct answer among the choices given is the last option. Galaxies are classified according to their shapes or visual morphology. There three main types of galaxies currently. They are the elliptical, spiral and irregular. Elliptical galaxies are like a spheriod or an elongated sphere. Spiral galaxies are characterized and distinguished by having a bulge, a disk and a halo. Lastly, irregular galaxies do not have regular or symmetrical shape.
