1.64 atm
PV = nRT —> P = nRT / V
n = 3 moles
R = 0.08206 L atm / mol K
T = 400 K
V = 60 L
P = (3)(0.08206)(400) / 60 = 1.64 atm
Answer:
Although all organic compounds contain carbon, and almost all have hydrogen, most of them contain other elements as well. The most common other elements in organic compounds are oxygen, nitrogen, sulfur, and the halogens.
Explanation:
I hope this helped!
I'm pretty sure that is correct too
Because Carbon has 4 VE and you have 4 atoms of hydrogen, each hydrogen atom has 1 VE (4 atoms = 4 VE)
4 + 4= 8 so yeah
Answer: A is condensation and B is freezing.
The process in which the gas changes to the liquid phase due to the removal of heat is known as condensation. Rains are formed in this way. The water vapour rises. As it raises above it loses heat and then cools down and condenses and comes down as rainfall.
The process in which the liquid changes to a solid on removal of heat is known as freezing. Formation of ice is an example. When the heat is removed at -4 degree Celsius the water freezes to ice.
For Ethanol:
D = m / V
D = 3.9 g / 5 mL
D = 0.78 g/mL
For benzene:
D = 4.4 g / 5 mL
D = 0.88 g/mL
benzene has a <span>higher density.
