The total ball pressure is sum of gauge pressure and atmospheric pressure
We know that atmospheric pressure = 101.325 kPa
so the total ball pressure = 61 kPa + 101.325 kPa = 162.325 kPa
Now we will use ideal gas equation as
PV = nRT
P = pressure = 162.325 kPa
V = 5.2 L
R = gas constant = 8.314 kPa L / mol K
T = 32 C = 273.15 + 32 = 305.15 K
n = moles = ?
Moles = PV / RT = 162.325 kPa X 5.2 / 305.15 X 8.314 = 0.332 moles
Answer:
The correct answer is , Weak bonds are transient and easily reversible.
Explanation:
Molecules or atom that associate to produce a weak bond can interact, and then separate .this is evident in hydrogen bond and vanderwaal force where the combined effect can produce emergent properties.
Example; the hydrogen bonds present in water molecule; when the bonds are broken using heat, the molecules are separated or released in form of vapor, this same molecule can combine again by condensation to produce liquid. showing clearly how transient and reversible the bonds between them is.
It's -Bohr's Model- becuase Dalton I dont think did a model. Thomson's was the "Plum Pudding Model." Ernest Rutherford drew one out(I dont know i dont have a model down though) so it the only one left is Dalton's Model which is it. (Hopefuly)
If water is deionized and it is consumed, it may cause people to urinate more and eliminate more electrolytes from the body.
Answer:
The temperature changes. Think of taking a cup of ice out by the pool in on a hot summer day. The ice begins to melt. The sun was changing its previous temperature. If it stayed the same, the now puddle of water would remain ice.
