Oh yeah I know it’s hard to get it
Answer: saturated
Explanation:
Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.
Supersaturated solution is defined as the solution in which more amount of solute particles is present than the solvent particles.
Unsaturated solution is defined as the solution in which more solute particles can be dissolved in the solvent.
As no more solid KCl dissolves and some solid KCl is still visible in the flask, the solution is termed as saturated
Answer:
XeF₂
Explanation:
Let's call the compound as XeaFb, where a and b are the number of atoms of each element. In the beginning, the partial pressure of XeaFb was 16 torr. By Dalton's Law, the total pressure of a gas mixture is the sum of the partial pressures of the components, so:
pH₂ = 64 - 16 = 48 torr
The reaction that happened was:
XeaFb + (b/2)H₂ → aXe + bHF
The stoichiometry of the reaction is 1:b/2:a:b. If all the XeaFb reacts:
1 torr of XeaFb -------- b/2 torr of H₂
16 torr -------- x
By a simple direct three rule:
x = 16b/2 = 8b torr of H₂ reacts
1 torr of XeaFb -------- a torr of Xe
16 torr -------- x
x = 16a torr of Xe is formed
Thus, 8b + 16a = 32
b + 2a = 4
The empirical formula is the minimum integer number of the elements in the compound. So, let's suppose a = 1 because fluorine can do only one bond, thus it's unprovable that will be more than one Xe bonded with one F:
b + 2*1 = 4
b = 2
Thus, the empirical formula is XeF₂.
