A 1.000 g sample of nitrogen combined with a 0.0720 g sample of hydrogen to form N2H2. What compound is formed if 1.000 g of nit
bazaltina [42]

Answer:

N₂H₆

Explanation:

A 1.000 g sample of nitrogen combined with a 0.0720 g sample of hydrogen to form N₂H₂ .

1.000 g of nitrogen combines with 0.2160 g of hydrogen in the next compound .

In this compound the component of nitrogen remains the same but the component of hydrogen becomes .2160 / .0720 = 3 times .

Hence component of hydrogen in the new compound will change from

H2 to H6 .

Hence the chemical formula of new compound will be

N₂H₆ .

Besides their shape, how does a 2p orbital differ from a 3d orbital? chegg.
Blababa [14]

Answer:

The 3p orbitals have the same general shape and are larger than 2p orbitals, but they differ in the number of nodes. You have probably noticed that the total number of nodes in an orbital is equal to n−1 , where n is the principal quantum number. Thus, a 2p orbital has 1 node, and a 3p orbital has 2 nodes.
