MgCl₂ +Na₂O →MgO + 2NaCl
the type of reaction above is double replacement reaction
explanation
Double replacement reaction is type of chemical reaction in which two compound react where positive ion (cation) and negative ion (anion) switch places forming two new compounds.
in reaction above the new compounds formed is MgO and NaCl as Mg²⁺ and O²⁻ switch their place to form MgO , while Na⁺ and Cl⁻ switch their place to form NaCl
