Chemistry
The formation of the iron(III) thiocyanate complex ion is an exothermic equilibrium system. For each change to the system, indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium. An up arrow indicates an increase in concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in the concentration.

Ответ:
This question appears incomplete
Explanation:
The equation for the formation of iron(III) thiocyanate complex ion is
Fe³⁺ + SCN⁻ ⇄ Fe(SCN)²⁺
Three factors affect the equilibrium of a reaction
temperaturepressure (in gases)concentrationSince the formation of Fe(SCN)²⁺ is an exothermic reaction (delta H is negative); an increase in temperature will favor the backward reaction and more reactants will be produced. When the temperature is however reduced, the forward reaction will be favored and more products will be produced.
When the concentration of the reactants increases, the forward reaction is favored and hence more Fe(SCN)²⁺ is produced. However, when the concentration of Fe(SCN)²⁺ decreases, the backward reaction is favored and more reactants are produced.
Ответ:
B. Hazardous waste.
D. Potential reactor accident.
Explanation:
The production of nuclear energy has two biggest drawbacks. First, the risk of accidents in nuclear reactor and the difficulties of storing nuclear waste, which implies the risk of contaminating locations and its surroudings as well.
