Solubility varies vastly. It depends on the solute, solvent, temperature, and pressure.
Answer:
% comp. H = 2.8%, % comp. Cl = 97.2%
Explanation:
HCl mass = mass of H + mass of Cl
HCL mass = 1.00794 + 35.453 = 36.46094
% comp. of H = 1.007694 / 36.46094 x 100 = around 2.8% (2.76376308455)
% comp. of Cl = 35.453 / 36.46094 x 100 = around 97.2% (97.2355622208)
Answer:
5.45mL
Explanation:
Using Boyle's law equation:
P1V1 = P2V2
Where; P1 = initial pressure
P2 = final pressure
V1 = initial volume
V2 = final volume
According to this question, P1 = 1.2atm, V1 = 25mL, P2 = 5.5atm, V2 = ?
1.2 × 25 = 5.5 × V2
30 = 5.5V2
V2 = 30/5.5
V2 = 5.45mL
Therefore, 5.45 mL sample of F2 gas will occupy a syringe at 5.5atm.
The best answer to the question presented above would be letter a. Changing the pressure of a system has the highest effect on a gaseous phase. Solids and liquids under pressure make little difference, while gas molecules have many behaviors due to change in pressure.
