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.
<span>Waves transfer energy through
vibration. just like electromagnetic waves, energy is transferred through
vibrations of electric and magnetic fields. In sound waves, energy is
transferred through vibration of air particles or particles of a solid through
which the sound travels. In water waves, energy is transferred through the
vibration of the water particles. While particles transfer energy through
conduction and convection.</span>
Initially when we dissolve a solute , rate of dissolution is far exceeding the rate of deposition. But as the concentration of solution increases , the rate of deposition also increases and a situation comes when rate of dissolution becomes equal to rate of deposition that situation is called dynamic equilibrium.
Saturated solution:
It is the solution in which dissolved solute is in dynamic equilibrium with undissolved solute, if we dissolve more solute into it it will not dissolve.
Unsaturated solution:
This solution contains less amount of solute than the equilibrium amount of it. If we dissolve more solute into it , it will dissolve.
Supersaturated solution:
This solution contains more amount of solute than its equilibrium concentration. These solution are unstable.
Answer:
Explanation:
This experiment converts mechanical energy to electrical energy. The movement of the magnet in and out of the coil is mechanical energy and the current induced in the circuit as a result of the magnet movement is electrical energy.
It should be noted that generally electromagnetic induction as described by faraday (and indeed the experiment described in the question) involves the transformation of mechanical energy into electrical energy. It's application is used in transformers, electric motors and generators.
The answer is 166 mL. You use the formula V1*M1=V2*M2. For what you're given you rearrange the formula to V1=M2*V2/M1 so V1= (0.500 mL)(0.100 M AgNO3)/(0.300 M AgNO3) = 166 mL
