Answer:
Unchanged.
Explanation:
Hello,
In this case, for the experiment you performed, as you previously removed the sodium chloride, its % salt calculation will not be affected by the lost of the sand. It is important to remember that such experiments must be performed carefully as the committed error is a high-impact factor regarding to the experiment's performance. It is important for you to remember that to separate the sodium chloride, it earlier dissolution in water allowed to be dissolved leveraging the insolubility of sand in water, thus, it was decanted easily.
Best regards.
The above ionic compound is called gallium sulphate
Water is your answer!!!!!!!!!
Answer:
maybe speak in english than we can understand and help you sorryy
The reaction has 
value of -296 kJ/mol, and the reaction is spontaneous. Hence, option A is correct.
The value of for the reaction is the change in the free energy. The for the reaction is calculated as:
<h3>Computation for
of the reaction</h3>
The given reaction is:
The change in enthalpy and entropy is given by the difference in product and reactant.
Thus, the change in free energy is given as:
Substituting the values in the above equation at a temperature of 300 K.
The negative value of represents the reaction to be spontaneous.
Thus, the reaction has value of -296 kJ/mol, and the reaction is spontaneous. Hence, option A is correct.
