<span>The ideal gas law.
PV=nRT
pressure x volume = moles x Faraday's constant x Temp Kelvin (C+273)
Original data
Pressure 1 atmosphere
Volume 1 liter
Temp 25C = 298K
New data
Volume 0.5 liter
pressure X
Temp 260C = 533K
P1v1T1 = P2v2T2
plug and chug.
(1)(1)(293) = (x)(0.5)(533)
Solve for X, which is the new pressure. </span>
Answer:
you would be trapped in the gravitational pull of a black hole
Explanation:
there is a black hole in the center of the galacy
Probably Fresh vegetables, it can rot out, that’d be my guess, it’s not canned
Answer: Option (d) is the correct answer.
Explanation:
As it is known that like dissolves like. So, water being a polar compound is able to dissolve only polar compounds.
Hence, a compound that is ionic or polar in nature will readily dissolve in water. Whereas non-polar compounds will be insoluble in water.
As
is a non-polar compound. Hence, it is insoluble in water.
On the other hand,
is a polar compound due to difference in electronegativity of chlorine and carbon atom there will be development of partial charges. Hence, there will be dipole-dipole forces existing between them.
Whereas
is an ionic compound and it will readily dissociate into ions when dissolved in water. Also, there will be ion-dipole interactions between sodium and nitrate ions.
Hence,
will readily dissolve in water.
Thus, we can conclude that the compounds correctly arranged in order of increasing solubility in water are

Answer: D
Explanation: Convection transfers heat by movement such as air and water.
