"Silver chloride is essentially insoluble in water" this statement is true for the equilibrium constant for the dissolution of silver chloride.
Option: b
<u>Explanation</u>:
As silver chloride is essentially insoluble in water but also show sparing solubility, its reason is explained through Fajan's rule. Therefore when AgCl added in water, equilibrium take place between undissolved and dissolved ions. While solubility product constant
for silver chloride is determined by equilibrium concentrations of dissolved ions. But solubility may vary also at different temperatures. Complete solubility is possible in ammonia solution as it form stable complex as water is not good ligand for Ag+.
To calculate
firstly molarity of ions are needed to be found with formula: 
Then at equilibrium cations and anions concentration is considered same hence:
![\left[\mathbf{A} \mathbf{g}^{+}\right]=[\mathbf{C} \mathbf{I}]=\text { molarity of ions }](https://tex.z-dn.net/?f=%5Cleft%5B%5Cmathbf%7BA%7D%20%5Cmathbf%7Bg%7D%5E%7B%2B%7D%5Cright%5D%3D%5B%5Cmathbf%7BC%7D%20%5Cmathbf%7BI%7D%5D%3D%5Ctext%20%7B%20molarity%20of%20ions%20%7D)
Hence from above data
can be calculated by:
= ![\left[\mathbf{A} \mathbf{g}^{+}\right] \cdot[\mathbf{C} \mathbf{I}]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cmathbf%7BA%7D%20%5Cmathbf%7Bg%7D%5E%7B%2B%7D%5Cright%5D%20%5Ccdot%5B%5Cmathbf%7BC%7D%20%5Cmathbf%7BI%7D%5D)
Answer:
Option D. Iron and sulfur react to form iron sulfide
Explanation:
Reaction of iron with sulphur is a chemical property and not a physical property.
Answer:
Full answer in explanation
Explanation:
- High Tide - when tides are at their highest elevation
- Low Tide - when tides are at their lowest elevation
- Spring Tide - when tides experience the greatest range between high and low; occur at New and Full Moons
- Neap Tide - when tides experience the least range between high and low; occur at 1st and 3rd Quarter Moons
- Gravitational Pull - the invisible force that exists between all objects that have mass. The greater the mass, the greater the effect of the force
- Tide - the daily change in ocean levels due to the gravitational force of the moon and the sun exerted on Earth
Hope this helps!
