A mile.

For reference, it's about 1,607 or so meters, and 1km is 1,000.

GalinKa [24]

Answer:

a) Fe(s) + Ni^2+(aq) ----> Fe^2+(aq) + Ni(s)

b) no reaction

c) no reaction

d) 2Mg(s) + 2H2O(l)-----> 2Mg^2+(aq) + O2(g) +4H^+(aq)

e) no reaction

Explanation:

It is important to say here that the ability of a particular chemical specie to displace another chemical specie is dependent on the relative standard reduction potentials of the species involved.

All the reactions stated above are redox reactions. Let us take reaction E as an example. Mg^2+ has a reduction potential of -2.37 V while Cr^3+ has a reduction potential of -0.74V. Since the reduction potential of magnesium is more negative than that of chromium, there is no reaction when a piece of chromium metal is dipped into a solution of Mg^2+.

Similarly, though metals displace hydrogen gas from dilute acids, metals that are less than hydrogen in the reactivity series cannot do that. This explains why there is no reaction when copper and silver are dipped into dilute acid solutions.

Reaction occurs when iron is dipped into a nickel solution because the reduction potential of Fe^2+ is far more negative than that of Ni^2+.

Which two factors must be considered when predicting whether two substances will dissolve in each other?
r-ruslan [8.4K]

The two factors must be considered when predicting whether two substances will dissolve in each other are type of bonds and size of the molecules are two factors.

<h3>What is solubility?</h3>

Solubility is the ability of solute particles to dissolve in any solvent, and solubility is directly proportional to the dissolving ability of the solute.

Solubility of any substance depends on the type of the bond present in the solute molecule i.e. polar or non polar. And it is also depends on the size of the solute as size defines the surface tenssion of the substance.

  • Number of bonds and shape of molecules are also define the solubility but not at that extent as their type and shape.

Hence type of bonds and size of the molecules are two factors.
