Possibly, Yes if it is proven
Answer:
it is directly related to the intermolecular forces present between its molecules
Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
1. Pressure decreases with increasing volume as the increased volume increases space for molecules to move around, thus decreasing the collisions and decreasing pressure.
2. A has a higher pressure given that the higher the n value, or moles present, the higher the pressure will be if everything else is held constant.
3. Gases have weaker intermolecular forces than liquids and solids.
4. Pressure must be 1/2, or 0.5 as PV=k, (P)(4)=(2), (P)=(2/4)
5. 2.25 L
6. Increasing space will decrease collisions and vice versa
7. 1122 2L bottles
8. 2.35 L
9. 2.1428 L
10. It would expand as they are directly proportional
11. 2.14959 L
12. 546K
13. .003663 atm`K
14. If pressure and temperature are directly proportional, then they increase or decrease at a constant rate
15. quadruples as they are directly proportional
16. 18.9963587 atm
Sorry hun, I gotta go. Good luck!
Answer:
The pH is 4.76
Explanation:
Step 1: Data given
Volume of a 0.476 M hydrocyanic acid solution = 29.8 mL = 0.0298 L
Volume of 0.487 M barium hydroxide solution = ?
Ka HCN = 6.2 * 10^-10
Step 2: Calculate pH
Hydrocyanic acid is a weak acid.
Barium hydroxide is a strong base.
The question asked = the pH BEFORE any base has been added, so we can ignore the base.
To calculate the pH of aweak acid, we need the pKa
HCN ⇔ H+ + CN-
Ka = [H+][CN-]/[HCN]
⇒ for weak acid: [H+]=[CN-]
Ka = [H+]²/[HCN]
[H+]² = [HCN]*Ka
[H+] = √([HCN]*Ka)
pH = -log(√([HCN]*Ka))
pH = -log(√(0.476 * 6.2*10^-10))
pH = 4.76
The pH is 4.76
