Answer:
C. Covalent Bond
Explanation:
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
 
        
             
        
        
        
Moles of phosphoric acid would be needed : 0.833
<h3>Further explanation</h3>
Given
15 grams of water
Required
moles of phosphoric acid
Solution
Reaction(decomposition) :
H3PO4 -> H2O + HPO3
mol water (H2O :
= mass : MW
= 15 g : 18 g/mol
= 0.833
From the equation, mol ratio H3PO4 = mol H2O = 1 : 1, so mol H3PO4 = 0.833
 
        
             
        
        
        
The new volume be if the pressure inside the balloon was reduced to 58kpa is 2.58 L.
<h3>What is ideal gas equation?</h3>
Ideal gas equation PV=nRT gives idea about the behavior of gases at different conditions and for this question the equation becomes:
P₁V₁ = P₂V₂, where
P₁ = initial pressure = 115.3 kpa
V₁ = initial volume = 1.3 L
P₂ = final pressure = 58 kpa
V₂ = final volume = ?
On putting all these values in the above equation, we get
V₂ = (115.3)(1.3) / (58) = 2.58 L
Hence resultant volume of gas is 2.58 L.
