The answer I believe is moist air because it doesn't have a reacting bond in the molecules
It's very simple.
Energy =
where, h= Planck's constant = 6.6 x
c= speed of light = 3 x
m/s
= wavelength
So, energy =
= 1.65 x
J
=1.65 x
KJ
Answer:
a) 52.8
Explanation:
M1V1 = M2V2
(7.91 M)(x ml) = (2.13 M)
(196.1 ml)
(7.91M) (xml) = 417.693 M.ml
x ml = 417.693/ 7.91
x = 52.8
