Answer:
Ba(NO₃)₂ (aq) + H₂SO₄ (aq) → BaSO₄ (s) + 2HNO₃ (aq)
Explanation:
The equation bellow can be explained by the dissociation of each specie:
Ba(NO₃)₂ (aq) → Ba²⁺ (aq) + 2NO₃⁻ (aq)
H₂SO₄ (aq) → 2H⁺ (aq) + SO₄²⁻ (aq)
The reaction will lead to the formation of solid barium sulfate and nitric acid.
The answer is A: biodegradable.
None of these because it doesn’t make since
The solid water begins to change into liquid water when the ice molecules<span> start to move around. Another way to say that a substance changes from the solid state to the liquid state is to say it </span>melts<span>. Te </span>ice<span> continues to </span>melt<span> as more </span>ice molecules<span> get enough energy to move around.</span>
Standard entropy of the compounds of interest are as follows,

= 212.1 J/K.mol

= 205.0 J/K.mol

= 213.6 J/K.mol

= 69.9 J/K.mol
Now for the reaction:
C6H12O6(s) + 6O2(g) —->6CO2(g) + 6H2O(l)
ΔS°reaction = ∑

- ∑

∴ ΔS°reaction =( 6

+ 6

) - (

+ 6

= 205.0 J/K.mol)
∴ ΔS°reaction = [6 (213.6) + 6 (69.9 )] - [(212.1) + 6(205.0)]
∴ ΔS°reaction = 258.9
