Answer:
6) 225.8 g
7) 1.01 g
8) 21.624 g
Explanation:
6) Molar Mass of Lithium Bromine: 86.845
86.845 * 2.6 = 225.8 g
7) Molar Mass of Neon: 20.180
20.180 * 0.05 = 1.01 g
8) Molar Mass of Water Vapor: 18.02
18.02 * 1.2 = 21.624 g
Answer: a) Partial pressure of argon is 0.673 atm.
b) Partial pressure of ethane is 0.427 atm.
Explanation:
According to the ideal gas equation:'
P = Pressure of the argon gas = ?
V= Volume of the gas = 1.00 L
T= Temperature of the gas = 25°C = 298 K (0°C = 273 K)
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas = 
Thus the partial pressure of argon is 0.673 atm.
b) According to Dalton's law, the total pressure is the sum of individual pressures.





Thus partial pressure of ethane is 0.427 atm.
Answer:
hi im new because of its solid state
Explanation:
Answer:
Lipid forms structures in cells and stores energy
Explanation:
Answer: It depends on the type of chemical reaction that formed the compound.
Explanation:
Exothermic reactions give off the heat to the reaction environment, so the compound feels hotter.
Endothermic reactions absorb the heat from the reaction environment and the compound feels cooler.
