aev [14]
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.

"Which statement is true about the removal of a terminal phosphate" from ATP? Choose one: A. The reaction is associated with a p
Mamont248 [21]

Answer:

C. The reaction is energetically favorable.

Explanation:

The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

ATP+H_2O\rightarrow ADP+P_i+\ energy

The Gibbs' free energy change of this reaction, \Delta G^0=-7.3\ kcal/mol

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.

A solution is prepared using 0.125 glucose C6H12O6 is enough water to make 250 g of total solution the concentration of the solu
Nastasia [14]

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 (10^6) parts by the mass of the solution.

Formula used :

ppm=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 10^6

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

ppm=\frac{0.125g}{250g}\times 10^6=500ppm

Hence, the concentration of solution in ppm is, 500 ppm
