Explanation:
Formula to calculate standard electrode potential is as follows.

= 0.535 - 1.065
= - 0.53 V
Also, it is known that relation between
and K is as follows.

ln K =
Substituting the given values into the above formula as follows.
ln K =
=
ln K = -41.28
K =
= 
Thus, we can conclude that the value of the equilibrium constant for the given reaction is
.
You did not provide the statements but a possible answer might be that the current atomic theory is sound and that technology that could challenge it does not exist at this time. There is no way to change it because no research can be done about it.
Answer:
Synthesis
Explanation:
They synthesize these chemicals
The chemical equation without coefficients is:
Ca + CO2 + O2 --------> Ca CO3
You can balance that equation by trial an error.
This is the chemical equation balanced:
2Ca + 2CO2 + O2 --------> 2Ca CO3
Count the atoms on each side to check the balance
Atom Left side right side
Ca 2 2
C 2 2
O 2*2 + 2 = 6 2*3 = 6
Then those are the coefficients:
a0 = 2
a1 = 2
a2 = 1
a3 = 2
It can be either they can have a negative or positive charge more specifically negatively charged molecule would called an anion and a positive one would be cation.
