in the chemical equation 2mg + o₂ → 2mgo, identify the reactant(s).\nmg and mgo\no2\nmg\nmg and o2\nyou have a list that shows how reactive metals are: potassium (most reactive) > sodium > calcium > magnesium > aluminum > zinc > iron > copper (least reactive). will magnesium replace zinc in a compound?\nno, because magnesium is lower on the list.\nyes, because magnesium is higher on the list.\nmaybe, it depends on the other elements.\nmetals cannot replace other metals.\nyou mix silver nitrate (agno₃) and sodium chloride (nacl) in water. two new compounds, silver chloride (agcl) and sodium nitrate (nano₃), are formed. what

Answer

Brief Explanations:

  1. In a chemical equation, reactants are on the left - hand side. In $2Mg + O_2\rightarrow2MgO$, the reactants are magnesium ($Mg$) and oxygen ($O_2$).
  2. In a reactivity series, a more reactive metal can displace a less reactive metal from its compound. Since magnesium is more reactive than zinc (higher on the reactivity list), it can replace zinc in a compound.

Answer:

  1. D. Mg and O2
  2. B. Yes, because magnesium is higher on the list.
