Answer:
Question:
A spring with a spring constant of 30 N/m is stretched 0.2 m from its equilibrium position. How much work must be done to stretch it an additional 0.1 m?
Elastic Potential Energy:
The work that needs to be done by any object is a form of energy. The work can be defined in terms of the work-energy theorem, which states that the work can either be the difference in the kinetic energy of a system or the difference in the potential energy of a system. There is a special type of potential energy reserved exclusively for
Cl-
(The - needs to be at the top by the way)
This shows it has gained an electron to form a stable ion which gives it a negative charge (as there are now more electrons then protons)

Answer : The value of is,
Explanation :
First we have to calculate the solubility in mole/L.
The balanced equilibrium reaction will be,
The expression for solubility constant for this reaction will be,
Now put the value of solubility in this expression, we get the of barium carbonate.
Therefore, the value of is,
