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.

Answer:carbon dioxide is released during combustion
Answer:
68g/mol
Explanation:
The formula of ammonium sulfide is:
Ammonium sulfide = (NH₄)₂S
The molar mass of a compound is the mass in gram of one mole of the substance. In a compound, it is expressed gram formula mass or gram-molecular weight.
It is determined by the addition of the component atomic masses and then expressed in grams;
Atomic mass of N = 14, H = 1 and S = 32
(NH₄)₂S = 2[14 + 4(1)] + 32 = 36 + 32 = 68g/mol
