Answer:
Precipitation reactions are ones in which at least one of the reactants is in the aqueous phase (i.e., dissolved in water), and a solid forms on the product side which was not present on the reactant side. If all the reactants are solid, then a solid product forming should not be called a precipitate. To be called a precipitate, an insoluble product must form from within solution, either from a solid and solute interacting, or from an interaction strictly between solutes.
Explanation:
Explanation:
The compound form in this type of combination is an ionic or electrovalent substance.
Some of the properties of xy, an electrovalent compound are;
- they are usually hard solids with a high melting point or liquids with high boiling points.
- they are soluble in water and insoluble in non-polar solvents.
- in molten form or aqueous form, they conduct electric current.
- in aqueous form, their reactions are usually fast.
Answer:
First, precipitate of AgCl is formed. Second, a soluble complex of silver and ammonia is formed. Third, AgCl is reproduced due to disappearance of ammonia complex in presence of .
Explanation:
In presence of NaCl, forms an insoluble precipitate of AgCl.
Reaction:
In presence of , AgCl gets dissolved into solution due to formation of soluble complex.
Reaction:
In presence of , complex gets destroyed and free again reacts with free to produce insoluble AgCl
Reaction:
Option A is the correct answer
Answer:
Gold
Explanation:
Platinum has an atomic number of 78.
78 + 1 = 79
The element with atomic number 79 is Gold.
