Have about 5 beakers all with different temperatures of water. Put in a teaspoon of salt at a time and when it stops dissolving stop adding and record how much salt it took. It should be more salt as the temperature rises. The independent variable is the waters temperature. The dependent variable is how much salt is used. Make sure that there is the same amount of water in each beaker. Or else it won’t work.
Answer:
C. The reaction is energetically favorable.
Explanation:
The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

The Gibbs' free energy change of this reaction, 
Hence, Option A is not correct.
It is a type of hydrolysis reaction in which water is being added to the molecule.
Hence, Option B is not correct.
The Gibbs' free energy change is negative which means that the reaction is energetically favorable.
Option C is correct.
Answer:
IONIC BOND
Explanation:
the force between oppositely charged IONS is and IONIC BOND
Answer : The concentration of solution in ppm is, 500 ppm
Solution : Given,
Mass of solute (glucose) = 0.125 g
Mas of solution = 250 g
Parts per million (ppm) : It is defined as the mass of a solute present in one million
parts by the mass of the solution.
Formula used :

Now put all the given values in this formula, we get

Hence, the concentration of solution in ppm is, 500 ppm
Answer: solids were liquds the form changes but it is still the same thing
