determine wheter each of the following reactions occur.
2Ni(s) + MgSO4(aq)--->
if it doesnt occur explain why
Find the Metal Activity Series chart in your chemistry book. The above reaction will occur if Ni is higher on the chart than Mg. Otherwise, no reaction occurs. You can also find the activity series below:

To determine whether the reaction between 2Ni(s) and MgSO4(aq) occurs, we need to check if a reaction is possible based on the activity series of metals.
The activity series of metals ranks metals from most reactive to least reactive. If a metal is more reactive than another metal, it can displace the less reactive metal from its compound.
In this case, nickel (Ni) is less reactive than magnesium (Mg) according to the activity series. This means that nickel cannot displace magnesium from its compound.
Therefore, the reaction between 2Ni(s) and MgSO4(aq) does not occur because nickel is not reactive enough to displace magnesium from magnesium sulfate (MgSO4).
To determine whether a chemical reaction occurs, we need to analyze the reactivity of the reactants and identify any possible products. In the given reaction:
2Ni(s) + MgSO4(aq) ---> ?
First, let's analyze the reactants:
- Ni(s) represents solid nickel.
- MgSO4(aq) represents an aqueous solution of magnesium sulfate.
As per the reaction, we have two solid nickel atoms reacting with an aqueous solution of magnesium sulfate. Generally, for a reaction to occur, we need a chemical reaction to take place between the elements in the reactants. Two ways to determine whether a reaction will occur are:
1. Reactivity Series: We can refer to the reactivity series which arranges metals in the order of their reactivity. In this case, nickel (Ni) is less reactive compared to magnesium (Mg), and since nickel is below magnesium in the reactivity series, it cannot displace magnesium to form a new compound. Therefore, we can conclude that a reaction does not occur.
2. Solubility: Another approach is to consider the solubility of the reactants. Magnesium sulfate (MgSO4) is soluble in water, resulting in the formation of magnesium ions (Mg^2+) and sulfate ions (SO4^2-). However, solid nickel (Ni) does not dissolve in water, so it remains in its solid state.
Based on these considerations, we can conclude that the reaction does not occur because nickel is less reactive than magnesium and cannot displace it, and there are no other evidence of a chemical reaction taking place.
