Question

1 numeric 10 points magnesium metal reacts with nitrogen gas to form magnesium nitride. write a balanced equation representing this reaction and report the coefficient of the product. your answer should be a positive whole number. answer 2 numeric 10 points iron metal reacts with chlorine gas to form iron (iii) chloride. write a balanced equation representing this reaction and report the coefficient of the iron reactant. your answer should be a positive whole number. answer

Explanation:

Step1: Write un - balanced reaction for magnesium

Magnesium (Mg) reacts with nitrogen gas ($N_2$) to form magnesium nitride ($Mg_3N_2$). The un - balanced equation is $Mg+N_2
ightarrow Mg_3N_2$.

Step2: Balance the equation

To balance the magnesium atoms, we put a 3 in front of Mg. The balanced equation is $3Mg + N_2
ightarrow Mg_3N_2$. The coefficient of the product ($Mg_3N_2$) is 1.

Step3: Write un - balanced reaction for iron

Iron (Fe) reacts with chlorine gas ($Cl_2$) to form iron(III) chloride ($FeCl_3$). The un - balanced equation is $Fe+Cl_2
ightarrow FeCl_3$.

Step4: Balance the equation

First, balance the chlorine atoms. The least common multiple of 2 and 3 for chlorine is 6. So we put a 3 in front of $Cl_2$ and a 2 in front of $FeCl_3$. Then to balance the iron atoms, we put a 2 in front of Fe. The balanced equation is $2Fe + 3Cl_2
ightarrow 2FeCl_3$. The coefficient of the iron reactant (Fe) is 2.
