Answer:

D

Aesthetics don't really matter, so option B follows it out.

Option C makes a little sense, but less so than Option D. They aren't nearly as heavy as some of our current energy production methods.

Solar panels are expensive,  hard to store properly, and most are between 15 and 20 percent efficiency, compared with a diesel motor's 40 percent.

How many moles of H2O2 are needed to react with 1.07 moles of N2H4?
I am Lyosha [343]

Answer:

2.14 moles of H₂O₂ are required

Explanation:

Given data:

Number of moles of H₂O₂ required = ?

Number of moles of N₂H₄ available = 1.07 mol

Solution:

Chemical equation:

N₂H₄  +   2H₂O₂       →   N₂ +  4H₂O

now we will compare the moles of H₂O₂ and N₂H₄

                          N₂H₄     :      H₂O₂  

                            1           :        2

                            1.07      :         2×1.07 = 2.14 mol
