Answer: answer A
Explanation: because it gives more detail and a summarizations
Answer:
Lead (II) Sulfate
Explanation:
Don't forget to add the (II) marking indicating that lead has a charge of 2+ (because Sulfate has a charge of 2-, balancing the ion).
Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
<h3>What is thermal equilibrium?</h3>
The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.
Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.
In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.

Explanation:
forward reaction
a reaction in which reactent react to form product is known as forward reaction
reverse reaction
a reaction in which product react to form reactent is known as reverse reaction
At equilibrium stage
In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.
changing amount of reactent and product
lechatlier principle
" if you impose any change in concentration ( reactant or product) , temperature or pressure on chemical system, the system response in that way that opposes the change "
