The balanced chemical equation for the above reaction is as follows ;
Mg + 2HCl —> MgCl2 + H2
The stoichiometry of Mg to HCl is 1:2
This means that 1 mol of Mg reacts with 2 mol of HCl
Equal amounts of both Mg and HCl have been added. One reagent is the limiting reactant and other reactant is in excess.
Limiting reactant is the reagent that is fully used up in the reaction and the amount of Product formed depends on the amount of limiting reactant present.
In this reaction if Mg is the limiting reactant, 4.40 moles of Mg should react with 4.40x2 -8.80 moles of HCl.
But only 4.40 moles of HCl present therefore HCl is the limiting reactant that reacts with 4.40/2 = 2.20 moles of Mg
Stoichiometry of HCl to MgCl2 is 2:1
Since HCl moles reacted -4.40 mol
Then MgCl2 moles formed are 4.40/2 = 2.20 mol of MgCl2

Explanation:
Heterogeneous:
- In the Heterogenous mixture, the components that are present in the mixture are not distributed uniformly.
- There are two or more than two phases present in a heterogeneous mixture.
- Examples of the heterogeneous mixture are - cereal in milk, gravel, pizza.
while
Homogeneous mixture:
- In Homogeneous mixture, the components that are present in the mixture are distributed uniformly throughout the solution.
- There is only one phase present in a homogenous type of solution.
- Examples of the homogenous mixture are- air, rainwater, steel.
Flerovium at its ground state is solid. It has electron configuration of [Rn]5f¹⁴6d¹⁰7s²7p². The expected number of valence electrons in a flerovium atom is 2. A ground state is the most stable state of an atom at satndard temperature and pressure.
Mercury is a homogenous mixture of two or more pure substances
True it also contains oxygen
