Hi,
The answer is HF since hydrogen bonds are can be formed only between Hydrogen and Fluorine, Oxygen or Nitrogen.
Answer : True
Explanation : When storing parts outside it is best to keep them under tarps or wrapped to stay in compliance is true, because when we store the parts outside the house there are high chances of the parts getting exposed to environmental moisture. Which will develop rust on the parts and make it useless later on. To avoid this situation it is safer to keep it covered under the tarps or wrap it with something which can protect it from moisture.
the one main difference between a hurricane and a typhoon is the specific location where the storm takes place!!
typhoons and hurricanes can reach sustained winds of an averaging 74 mph.
Answer:
125.84 g/mol is the molar mass of the unknown gas.
Explanation:
Let the volume of the gases effusing out be V.
Effusion rate of the unknown gas =
Effusion rate of the nitrogen gas =
Molar mass of unknown gas = m
Mass of nitrogen gas = 28 g/mol
Graham's law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
125.84 g/mol is the molar mass of the unknown gas.
