6Li(s)+N2=2LiN
the mass of N2 needed to react with .536 moles of Li

Mass = 3.752 g

Explanation:

Given data:

Number of moles of Li = 0.536 mol

Mass of N₂ needed = ?

Solution:

Chemical equation:

2Li + N₂   →  2LiN

Now we we will compare the moles of Li and N₂.

                           Li           :        N₂

                            2          :          1

                          0.536    :         1/2×0.536 = 0.268 mol

Mass of N₂

Mass = number of moles × molar mass

Mass = 0.268 mol × 14 g/mol

Mass = 3.752 g

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
