Answer : The value of for the reaction is -959.1 kJ
Explanation :
The given balanced chemical reaction is,
First we have to calculate the enthalpy of reaction .
where,
= enthalpy of reaction = ?
n = number of moles
= standard enthalpy of formation
Now put all the given values in this expression, we get:
conversion used : (1 kJ = 1000 J)
Now we have to calculate the entropy of reaction .
where,
= entropy of reaction = ?
n = number of moles
= standard entropy of formation
Now put all the given values in this expression, we get:
Now we have to calculate the Gibbs free energy of reaction .
As we know that,
At room temperature, the temperature is 500 K.
Therefore, the value of for the reaction is -959.1 kJ
Answer:Science is a systematic and logical approach to discovering how things in the universe work. ... True to this definition, science aims for measurable results through testing and analysis. Science is based on fact, not opinion or preferences. The process of science is designed to challenge ideas through research

Answer: no
Explanation:
Atoms are not and have never been alive so they can't be considered dead. they simply do not meet any reasonable of life, primarily because they are not complex.
The molar mass of potassium or K is 39.09 g,s/mole and the atomic mass is 39.09 u+-0.0001u. Potassium was first discovered by Humphrey Davey and was first found in the ashes of plants. It also occurs in the mineral sylvite or KCL and is mined as such.
