Answer : The value of for this reaction is 36.18 kJ
Explanation :
First law of thermodynamic : It states that the energy can not be created or destroyed, it can only change or transfer from one state to another state.
As per first law of thermodynamic,
where,
= internal energy of the system
q = heat added or rejected by the system
w = work done
As we are given that:
q = 38.65 kJ
w = -2.47 kJ (system work done on surrounding)
Now put all the given values in the above expression, we get:
Therefore, the value of for this reaction is 36.18 kJ
Answer:
6. protons, mass number from the atomic number
7. Li= ,
False. The principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
<h3>What is Archimedes' principle?</h3>
It is a theory propounded by Archimedes. It opines that a floating body is acted upon by a buoyant force.
The buoyant force is the same as the weight of the fluid displaced by the floating body.
Thus, instead of saying 'the buoyant force is equal to the blank of the fluid displaced', it is actually 'the buoyant force is equal to the weight of the fluid displaced'.
