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: probably c i'm not too good with chemistry however i can tell u how got it
Explanation: 27/13Al+1/0
or
simplify 27lA>13 which = 1>0
in my terms 1/0n the answer is c
btw no worries i tend to add a lot of people on brainly and when i send them a request i try to help them the best i can regardless of the trouble it takes, i'm not some crazy weirdo with a crazy crush, that's what all my friends thought, but nah not true i just like to help anyways.. uhm lemme stop typing
Mixtures:
physically combined
components retain properties
compounds:
chemically combined
components change properties
both:
made of elements
variable proportions
fixed properties
2 or more compounds
hope this helps
comment me if you have any questions
Answer: no you need a balance skall to make it the correct balance that you want. yes the hypothesis is correct because you change the balance with your balance scale so obviously it's going to make your hypothesis higher.
Explanation: I HOPE THAT HELPED.
