This is an incomplete question, here is a complete question.
Calculate the solubility of each of the following compounds in moles per liter. Ignore any acid-base properties.
CaCO₃, Ksp = 8.7 × 10⁻⁹
Answer : The solubility of CaCO₃ is,
Explanation :
As we know that CaCO₃ dissociates to give ion and
ion.
The solubility equilibrium reaction will be:
The expression for solubility constant for this reaction will be,
Let solubility of CaCO₃ be, 's'
Therefore, the solubility of CaCO₃ is,
Answer:
In Cl, the 2 is a subscript because it indicates there are 2 of the same elements. The Lewis structure would display it as Cl-Cl.
On the other hand, a superscript would indicate a specific charge.
All subscripts show the amount of the specific element there is.
An example would be O or N
, they both show that there are 2 of the same elements.
If the subscript is outside a parenthesis such as it indicates there are 2
molecules.
Answer:
d. inversely proportional to the volume of its container.
Explanation:
Boyle's law states that at constant temperature and number of moles, the pressure of the gas is inversely proportional to the volume of the gas.
Thus, P ∝ T
P is the pressure
T is the temperature
For two gases at same temperature, the law can be written as:-
<u>Thus, according to the question, the answer is:- d. inversely proportional to the volume of its container.</u>
