The answer is protons.
There you go!
MgCl₂ +Na₂O →MgO + 2NaCl
the type of reaction above is double replacement reaction
<u><em> explanation</em></u>
<u><em> </em></u> 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

Universe grows and cools until 100 seconds after the Big Bang. The temperature is 1 billion degrees, 109 K. Electrons and positrons annihilate to make more photons, while protons and neutrons combine to make deuterons. Almost all of the deuterons combine to make helium.
Hope this helped.
