Answer:
A
Explanation:
One of the main complaints about hydropower is that it will change the ecosystem. You can read about the history of any dam and you will find that most of them have involved evacuation. That means that farmland was lost and replaced by a lake behind the dam. The energy comes from water cascading over the top of the dam to its bottom.
It does not produce radiation.
It does not burn fossil fuels. It's clean and does not pollute the air.
So there are no greenhouse gases involoved.
Answer:
The correct answer is The equilibrium constant for this reaction changes as the pH changes.
Explanation:
The equilibrium constant of a reaction depends of pH and viceverca.There is a equation that link pH with equilibrium constant Ka(for assumption).The equation is given below,
pH=pKa+log[A-/HA]
where[A-] is the concentration of conjugate base and [HA] is the concentration of conjugate acid.
The molality of the solution can be defined as moles of solute per kilogram of solvent.
Molality=3.8 moles/0.185 kg
=20.54 molal
The change in the temperature can be calculated as the product of boiling point constant and molality.
ΔTb=Kb×m=0.51 °C/m×20.54 m=10.47 °C.
The boiling point of the solution will be = 100 °C + 10.47 °C
=110.47 °C
It is the emission of a proton that has the greatest penetrating power. This is the main reason why protons are used in many nuclear energy uses and medicine.
