determine wheter each of the following reactions occur.
2Ni(s) + MgSO4(aq)--->
if it doesnt occur explain why
To determine if a reaction occurs between 2Ni(s) and MgSO4(aq), we need to check if there is a potential reaction between the two compounds. To do this, we can look at the activity series for metals and the solubility rules for ionic compounds.
1. Activity series for metals: The activity series is a list of metals ranked in order of their reactivity. If a metal is higher in the activity series than another metal, it can displace the lower metal from its compound. In this case, nickel (Ni) is below magnesium (Mg) in the activity series, so nickel cannot displace magnesium from its compound.
2. Solubility rules for ionic compounds: The solubility rules provide guidelines on the solubility of different compounds in water. Magnesium sulfate (MgSO4) is a soluble ionic compound, meaning it dissociates completely in water to form Mg2+ and SO4- ions. Nickel (Ni) is a metal, which does not typically dissolve in water.
Based on the activity series and solubility rules, we can conclude that a reaction does not occur between 2Ni(s) and MgSO4(aq). Nickel cannot displace magnesium from magnesium sulfate, and nickel does not dissolve in water to react with the sulfate ions.
Therefore, the reaction 2Ni(s) + MgSO4(aq) does not occur.
