Answer:
Hydrogen gas is highly combustible, and leakage can lead to a catastrophic explosion. The concentration of hydrogen gas in the furnace is held constant at 6.022 x 1023 atoms/m3 and is effectively 0 outside the furnace. Calculate the mass flow rate (mg/hr) of hydrogen from the furnace if the diffusivity of hydrogen through the glass is 2 x 10-5 m2 /s. You may assume steady state behavior and constant diffusivity. You may assume that diffusion only occurs through the glass. The molar mass of hydrogen can be taken as 2 g/mol
Explanation:
It is so because warm air is lighter than cold air. Cold air means the molecules are not moving as much, so they will feel like sticking together and will not jump around as molecules in warm air will(higher temp. means higher KE). Think of a solid, colder solids are much heavier than warmer ones(think of ice-starts melting).
Answer:
Ethanol has covalent intramolecular bonds. Ethanol is polar. Ethanol has dispersion intermolecular forces. Dimethyl ether is polar. Dimethyl ether forms hydrogen bonds. Dimethyl ether has dispersion intermolecular forces.
Explanation:
Ethanol is not a carboxylic acid. It is an alcohol and it has covelent intramolecular bonds. It is polar and it also has dispersion intermolecular forces.
Dimethyl ether is also polar and it has forms hydrogen bonds. It also has dispersion intermolecular forces. Dimethyl ether does not have ionic intramolecular forces
The atomic # and the mass #.
