Which of these ions will spontaneously react with ni(s) in solution? which of these ions will spontaneously react with in soluti
pickupchik [31]
Nickel metal will react spontaneously with the aqueous lead solution [Pb2+(aq)]. 

Oxidation is a chemical reaction involving the loss of electrons. In the reactivity series of metals, chromium, barium, and lithium are more reactive or more easily oxidized than nickel. 

In the given problem, because nickel is in its elemental (solid metal) form, for it to react with the solution, it will have to be converted into its cationic form (which is positively-charged) by losing electrons. However, if the solution that nickel is reacted with is more easily oxidized compared to nickel, then the reaction will not be spontaneous because nickel is stable in this case. 

On the other hand, if nickel is immersed in a solution of a metal which is more stable than it is, such as lead, nickel will be oxidized and lose its electrons to the more stable metal. The more stable metal in solution will accept the lost electrons of nickel and form a solid deposit, while nickel will be in its ionic form in solution. 

Below is a reaction between nickel metal and aqueous lead nitrate solution.

Which of the following stage is also known as the unstable stage?
Lelechka [254]

Transient stage is also called the unstable stage and in this stage, there is a gradual decrease in deformation rate to a definite constant value.

<h3>What is Transient stage ?</h3>

A transient state is when a process variable or variables changes, but before the system reaches a steady state.

Transient time is the time it takes for a circuit to change from one steady state to the next.

Therefore, Transient stage is also called the unstable stage and in this stage, there is a gradual decrease in deformation rate to a definite constant value.

Was the acetylacetone miscible with water? What about if NH3 is added to the solution? Why?
luda_lava [24]

Answer:

See explanation

Explanation:

The compound is acetylacetone. This compound is immiscible with water because it is completely nonpolar.

However the introduction of ammonia, leads to the ionization of the specie. In the presence of a base(such as NH3), the molecule acetylacetone is deprotonated and its corresponding anion is formed. This anion can now interact with water and become miscible with it.
