What reaction is depicted by the given equation: au3 3e− au
1 answer:
This is a reduction half-reaction. Initially, gold exists as 
, and after the reaction, it has been converted to elemental gold. To make this possible, three electrons must be added to <span>
. This fits within the definition of reduction reactions, where the reactant gains electrons in the reaction.</span>

Answer:
2.42L
Explanation:
Given parameters:
V₁ = 1.8L
T₁ = 293K
P₁ = 101.3kPa
P₂ = 67.6kPa
T₂ = 263K
Unknown:
V₂ = ?
Solution:
To solve this problem, we are going to use the combined gas law to find the final volume of the gas. The combined gas law expression combines the equation of Boyle's law, Charles's law and Avogadro's law;
All the units are in the appropriate form. We just substitute and solve for the unknown;
101.3 x 1.8 / 293 = 67.6 x V₂ / 263
V₂ = 2.42L
