MgCl₂ + Na₂CO₃ ==> MgCO₃ + 2NaCl.✅
Answer:
The pressure increases.
Explanation:
According to Avogadro's principle, equal volume of gases contains the same number of moles. From the reaction equation, there is a decrease in the total number of moles from reactant to product indicating a decrease in volume (as per Avogadro) and an increase in pressure according to Boyle's Law-Volume is inversely proportional to pressure.
