Answer:
The answer to your question is V2 = 867.3 mL
Explanation:
Data
Volume 1 = V1 = 400 ml
Temperature 1 = T1 = 22°C
Pressure 1 = P1 = 760 mmHg
Volume 2 = V2 = ?
Temperature 2 = T2 = 30°C
Pressure 2 = P2 = 360 mmHg
Process
1.- Convert Celsius to Kelvin
T1 = 22 + 273 = 295°K
T2 = 30 + 273 = 303°K
2.- Use the Combined gas law
P1V1/T1 = P2V2/T2
- Solve for V2
V2 = P1V1T2 / T1P2
- Substitution
V2 = (760 x 400 x 303) / (295 x 360)
- Simplification
V2 = 92112000 / 106200
-Result
V2 = 867.3 mL
Answer:
Its neither a myth nor deadly
Explanation:
Bizarre hexagonal clouds forming above the Bermuda Triangle may be the reason why dozens of ships and planes have mysteriously vanished in the notorious patch of sea, according to scientists.
According to the new theory, clouds over the Bermuda Triangle are like “air bombs” strong enough to cause ship and plane wrecks. The strange “hexagonal” shaped clouds were discovered using radar satellite imagery, which were between 20 and 50 miles wide forming over the water.
Answer:
False.
Explanation:
The given statement is false because for hot vacuum filtration, the filter paper should be wet rather than dry when pouring the hot solution into the Buchner funnel. This is because The possible explanation the filter paper needs to be wetted is not only to allow it to adhere to the funnel, but also to promote the solute to filter down readily across its pores of the paper without wetting it (this is true for organic and aqueous solvents).

Answer:
Water has polar O-H bonds. The negative O atoms attract the positive H atoms in nearby molecules, leading to the unusually strong type of dipole-dipole force called a hydrogen bond. Since water has hydrogen bonds, it also has dipole-induced dipole and London dispersion forces.
