Chemistry
1 answer:
yulyashka [42]3 years ago

When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone.

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

Calculate the density in g/mL of 2.0L of gasoline that weighs 1.26 kg
quester [9]
2.0 L in mL :

2.0 x 1000 => 2000 mL 

1.26 kg in g :

1.26 x 1000 => 1260 g

D = mass / volume

D = 1260 / 2000

D = 0.63 g/mL

hope this helps!
