<span>What is the 10% energy rule?</span>
The 10% energy rule means that when energy is passed into
the ecosystem from one trophic level into the next, only ten percent energy
will be passed on.
Answer: 204 L
Explanation:
According to ideal gas equation:
P = pressure of gas = 0.262 atm
V = Volume of gas = ?
n = number of moles =
R = gas constant =
T =temperature =
Thus volume occupied by 11.7 g of Helium in a balloon is 204L

Answer:
The heat of vaporization of acetaldehyde is 25.72 kJ/mol.
Explanation:
Mass of acetaldehyde = 50.0 g
Molar mass of acetaldehyde = 44.05 g/mol
Moles of acetaldehyde =
Amount of energy required to vaporize 50.0 grams of acetaldehyde = Q
Q = 29.2 kJ
The heat of vaporization of acetaldehyde :
