1 kg ----------------- 1000000 mg
0.00576 kg -------- ??
0.00576 x 1000000 / 1 => 5760 mg
hope this helps!
Krypton is the only element that begins with the letter K.
<span>Chemical changes result in the formation of new substances, and the changes that occur cannot be reversed (at least without other chemical changes). The heat from frying an egg causes the egg's protein to change permanently in texture and in appearance through a process called denaturing.
The answer is B. Frying an egg.

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 %
A homogeneous mixture, the substances are uniformly distributed throughout the mixture
