Spontaneous is no spontaneous
A. Atomic radius increases
Answer:
MgCl2 - 6H2O
203.3 mol
MgCl2 + 2Na = 2NaCl + Mg
22.6g
Explanation:
1. Write the formula of hydrate and find molar mass.
2. Write a balanced single replacement (don't include H2O)
3. Do the given/wanted calculation (include H2O in molar mass of given)
Answer:
Kf
Explanation:
The stability constant Kf of a given complex specie is an equilibrium constant that represents the formation of that particular complex specie in solution. It measures the strength of the interaction between the ligands and metal that form the particular complex specie. The magnitude of Kf shows how easily a complex specie is formed in solution.
Hence if I want to dissolve the bromides or chlorides of silver which are ordinarily insoluble in water by means of complex formation, the magnitude of the stability constant for each particular complex specie is important as it gives information regarding the thermodynamic feasibility of the process.
