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
A 2% saltwater is a dilute solution in which the solvent is water and the solute is salt. The solvent is the component of the solution which comprise a large percentage while the solute comprise the smaller part. When alcohol is added, the solute still is salt and the solvent is the mixture of water and alcohol.
Condensation is the warming process. Heat energy is released by the gas when it condenses into a liquid.
Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere.
I really do hope this helps and i hope you have a wonderful weekend

Cl-
(The - needs to be at the top by the way)
This shows it has gained an electron to form a stable ion which gives it a negative charge (as there are now more electrons then protons)

Answer:
Below -38*C Mercury will freeze. Above 350*C Mercury will begin to boil.
Explanation:
Each element has different boiling and freezing points. For mercury this is these set constraints.
