Answer:
1x10⁻¹²
Explanation:
- Cu₂S(s) ⇌ 2Cu⁺(aq) + S²⁻(aq)
At equilibrium:
The equilibrium constant for the the reaction can be written as:
[Cu⁺] is squared because it has a stoichiometric coefficient of 2 in the reaction. <em>Cu₂S has no effect on the constant because it is a solid</em>.
Now we can <u>calculate the equilibrium constant</u>:
- Keq = (1.0x10⁻⁵)² * 1.0x10⁻² = 1x10⁻¹²

A. The box will move to the right
N(Mg) : n(O)
1 : 1
the ratio is one to one
The wood can't do the same function as done by the water and glass in the same virtual experiment due to its different chemical composition.
The light will not pass through the wood due to its translucent behaviour that prevents light to pass through it as compared to water and glass which are transparent materials and light can easily pass through it.
So using wood as a bottom material instead of glass and water will not perform the same function as perform by water and glass in the same virtual experiment so we can conclude that wood can't perform the same function in the experiment.
