84. heavy water, d2o (molar mass = 20.03 g mol–1), can be separated from ordinary water, h2o (molar mass = 18.01), as a result of the difference in the relative rates of diffusion of the molecules in the gas phase. calculate the relative rates of diffusion of h2o and d2o.

relative rate of diffusion is 1.05

Explanation:

According to Graham's law of difussion:

Rate of diffusion is inversely proportional to the square root of molecular weight of a molecule.

For two given molecules:

The given molecules are

Water = 18.01

Heavy water =20.03

Thus the relative rate of diffusion will be:

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
