Using the solubility curve, what is the effect of increased temperature on the solubility of KBr in 100 grams of water? The solu
galina1969 [7]
The graph is needed to answer this question.

Solubility may increase or decrease with temperature depending on the properties of the solute and the solvent.

It is quite common that the solubility of the ionic compounds, like KBr, in water increases with temperature.

Use your solubility curve for the KBr and you wiil see a line that starts at a solubility a little greater than 50 grams of the salt in 100 grams of water for temperaute 0°C and increase linearly until almost 100 grams of the salt in 100 grams of water at 100°C.

So, in this case you can affirm that the solubility of KBr increases with the temperature.

Answer: the second option: the solubility increases.

A meal containing a burger, fries, and a milkshake contains 53.0 grams of fat, 38.0 grams of protein, and 152 grams of carbohydr
ollegr [7]

Answer:

4.8 h

Explanation:

The meal contains 53.0 grams of fat. If fat provides 38 kJ/g, the energy supplied is:

53.0 g × 38 kJ/g = 2.0 × 10³ kJ

The meal contains 38.0 grams of protein. If protein provides 17 kJ/g, the energy supplied is:

38.0 g × 17 kJ/g = 6.5 × 10² kJ

The meal contains 152 grams of carbohydrate. If carbohydrate provides 17 kJ/g, the energy supplied is:

152 g × 17 kJ/g = 2.6 × 10³ kJ

The total energy supplied is:

2.0 × 10³ kJ + 6.5 × 10² kJ + 2.6 × 10³ kJ = 5.3 × 10³ kJ

Swimming burns 1100.0 kJ/hour. The time required to burn 5.3 × 10³ kJ is:

5.3 × 10³ kJ × (1 h/1100.0 kJ) = 4.8 h
