Answer:
Zinc Chloride + Difluorine -----> Zinc Fluoride + Dichlorine
Explanation:
ZnCl2 + F2 → ZnF2 + Cl2
The second shell is left at 7, it should be filled to 8 to go to the next shell.
Strong acids can dissolve the salts of weak acid. When we consider the different salts of silver:
Salts of silver with the conjugate bases of a weak acid are soluble in strong acidic solutions. Some of these salts are:
Salts of silver with the conjugate bases of a strong acid are not affected by change in pH:
These two salts with Chloride and sulfate ions are not soluble in acidic solutions as the salts of silver with the conjugate bases of a strong acid are not soluble in acidic solutions, they remain unaffected by any change in pH.
So for salts of Ag and Ba with the conjugate bases of a weak acid, solubility is increased upon the addition of an acid. So, the interference from the ions of weak acids can be removed by decreasing the pH.
Answer:
Iron, as well as iron alloys, rusts because of a chemical reaction known as oxidation. When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide. ... Both oxygen and moisture are catalysts for rusting.
