Question

An atom of magnesium and two atoms of chloride react and yield the compound of magnesium chloride which option represents the scenario as a chemical equation?

Answer 1

Answer:

Option E is correct.

Explanation:

An atom of magnesium and two atoms of chloride react and yield the compound of magnesium chloride

Mg + 2Cl -> MgCl₂

Therefore, the correct option is the option E.

Option A shows the decomposition of MgCl₂ to two Mg atom and 1 Cl atom. The reaction is unbalanced. The question has asked for the formation of MgCl₂. Option A is incorrect.  

Similarly, option C shows the decomposition of MgCl₂, however, the reaction is balanced. Option C is incorrect.

Option B is incorrect as there are 2 Cl atoms on the reactant side but no Mg atom.  

Option D is incorrect as there only 1 Mg atom on the reactant side but no Cl atoms.  

Answer 2

Answer:

$\boxed{\text{Mg + 2Cl \longrightarrow MgCl _{2} }}$

Explanation:

Convert the word equation to a chemical equation.

one atom magnesium + two atoms Cl form magnesium chloride

                Mg               +          2Cl           ⟶             MgCl₂
