Answer:
The correct answer for the reverse reaction is the third option starting from top.
Explanation:
If we examine the given chemical equation:
2SO2 + O2 ⇌ 2SO3
The double arrow indicates that the reaction goes in both directions:
2SO2 + O2 -> 2SO3
2SO3 -> 2SO2 + O2
However, the closest option for the real situation would be the product from the semirreaction reacting in turn with oxygen:
2SO3 + O2 -> 2SO2
Thus, the correct answer is the third.
This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
<h2>The required "option is b) Fusion"</h2>
Explanation:
- During fission, the nucleus of higher mass is broken down into the nucleus of lower mass in which a high amount of energy is released.
- During fusion two nuclei combine or fuses to form a larger molecule of higher mass for which a high amount of energy is provided.
- Therefore, the higher mass of a substance is formed with the combination of lower mass of a substance during the process of fusion.
- Hence, the required option is Fusion.

Answer:
240.17 g Ba3(PO4)2
Explanation:
1. Determine the limiting reactant.
2H3PO4 + 3Ba(OH)2 --> Ba3(PO4)2 + 6H2O
moles H3PO4 = M x V = 3 x 0.286 = .858 moles H3PO4
moles Ba(OH)2 = M x V = 1.4 x 0.855 = 1.197 moles Ba(OH)2
ratio Ba(OH)2 : H3PO4 = 1.197: .858 = 1.39: 1
stoichiometric ratio Ba(OH)2 : H3PO4 = 3:2
Ba(OH)2is the limiting reactant
MM Ba3(PO4)2 = 601.92 g/mol
g Ba3(PO4)2 = moles Ba(OH)2 x(1 mol Ba3(PO4)2/3 moles Ba(OH)2) x (MM Ba3(PO4)2/ 1mol Ba3(PO4)2) = 1.197 x 1/3 x 601.92 = 240.17 g Ba3(PO4)2
