Dinitrogen tetroxide decomposes to give nitrogen dioxide according to equation below
N2O4--->2NO2
According to avogadros law
1 moles =22.4 l
what about 2.45 l
=2.45l x1 mole/22.4=0.1094 moles
by use of reacting ratio that 1 :2
the moles of No2 = 0.1094 x2=0.2188 moles
1 moles= 22.4 l
what about 0.2188moles
=(0.2188moles x22.4 l) /1moles=4.90 L
Answer:
D. Visible Light
Explanation:
D is the right answer because visible light is perceived by humans as color and the rest aren't visible at all. For example, if you broke a bone and have to have an X-ray done, you can't see the x-rays. When you are heating something in the microwave, you can't see the waves. And when you are listening to the radio in the car, you also can't see the waves.
This is true because the water would have gravitational potential energy that is caused by the water being held back by the dam and the water wanting to flow down.
This can be converted into kinetic energy when given the chance to, such as having a turbine on the dam.
Hope this helps! :)
Gas is a substance that will not phase change.
And vapor is a substance above it's boiling point temperature.
