I think its called refraction
Answer:
correct
Explanation:
makes sense just re-write!
2.7 x 10^24, since 4.5 has two significant figures.
<span>Na --> Na+ + e- E = +2.71
2H2O + 2 e- --> H2 + 2 OH- E = -0.83
Delta E = 2.71 - 0.83 = 1.88 Volts
You know the reaction is spontaneous because Ecell is positive.
Delta Go = - n F Delta E
Delta Go = - 2mol (96485 J/volt mol) (1.88 V)
Delta go = -3.62X10^5 J/mol = -326 kJ/mol
Yes, it is VERY spontaneous.</span>
Hey there!
The answer/answers: <span>The four main greenhouse gases that support the natural greenhouse effect are:
</span><span>H2O (water vapor)
CO2 (carbon dioxide)
CH4 (methane)
and
NO (nitrous oxide)
These</span><span> greenhouse gas traps heat from the sun

Hopes this Helps u :D
