120 barrels = 15120 quarts
To convert from barrels to quarts, you just need to multiply the value in barrels by 126 (the conversion factor).
So, 120 barrels = 120 × 126 = 15120 quarts.
The atom that is oxidized : Cr
The oxidizing agent : H₃PO₄
<h3>Further explanation</h3>
Reaction
2 H₃PO₄ (aq) + 2Cr(s) → 2 CrPO₄ (aq) + 3H₂(g)
Atoms undergoing a reduction reaction (decrease in oxidation number) and an oxidation reaction (increase in oxidation number)
H⁺(in H₃PO₄) =+1
H₂=0
Cr = 0
Cr³⁺(in CrPO₄ )
the oxidizing agent.⇒which undergoes a reduction reaction and oxidizes another compound/element : H₃PO₄
The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:
Sodium hydroxide + Sulfuric acid → Sodium sulfate +water
<h3>What is the balanced molecular equation?</h3>
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
In the given reaction, the reactants have been sulfuric acid and sodium hydroxide. Thus, these are written on the left side of the right arrow. The sodium sulfate and water have been the products and written on the right side of the right arrow.
The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:
