Atoms become unstable when the neutrons and protons are off-balance. Neutrons serve as a type of atomic “glue” that holds the nucleus together. Throw that ratio off balance, and the whole atom goes kaput.
The answer which defines exothermic reaction is
a process in which energy is released as heat ( answer A)
<u><em>Explanation</em></u>
Exothermic reaction is a chemical reaction in which energy is released into environment in form of heat.
<u> For example of exothermic reaction</u>
Is a combustion reaction such as lighting a candle whereby oxygen react with wax to produce carbon (iV) oxide, water and heat.
Answer: So, why is the snow and ice blue? Similar to water, snow absorbs red and yellow light, leaving blue light behind to give it that bluish appearance. If snow is only a few inches deep, none of the light will be left behind, making the snow appear white. The deeper the snow, the more blue light is left behind.
Explanation:
It is called a proton I hope this helps
Delta Go = -RTlnKeq
delta Go = 5.95 kJ/mole = 5.95 X 1000 = 5950 J/mole ( 1 kj = 1000 J )
putting the values and finding Keq
5950 = -8.314 X 298 X ln Keq
ln Keq = -5950 / 2477.572 = -2.4015
Keq = e^-2.402 = 0.0905
suppose the equilibrium reaction is :-
chair 1 <--------> chair 2
now as Keq is less than 1 ....so chair 1 will be more stable
Keq = [chair2]/[chair 1 ] = 0.0905
this means that [chair 2] ~ 0.0905 and [chair 1] ~ 1
[total] = [chair 2] + [chair 1] ~ 1 + 0.0905= 1.0905
percentage of chair 1 = [chair 1] / [total] = 1 / 1.0905 X 100 = 91.70 %
