Question

show me the balance equation for mag nesium + oxygen - magnesium oxide​

Answer 1

Answer:

Mg+O2→ MgO

Balanced Equation

2Mg + O2→ 2MgO

Thank You!

Answer 2

Answer:

$\underline{\red{\bf{\leadsto Reaction\:of\: Magnesium\:and\:Oxygen:}}}$

• Magnesium reacts with oxygen to form Magnesium Oxide.
• The magnesium ribbon burns with a dazzling white flame.
• When we add water to Magnesium Oxide , Magnesium hydroxide is formed which is basic in nature.

$\underline{\red{\bf{\leadsto Skeletal\: equation:}}}$

$\green{\sf{ \longmapsto Magnesium + Oxygen \longrightarrow Magnesium Oxide}}$

$\purple{\sf{\longmapsto Mg+ O_{2}\longrightarrow MgO}}$

• The number of Magnesium atoms on both sides is same i.e. one.

• Now we can observe here that on LHS , we have 2 oxygen atoms , but on RHS we have only 1 oxygen atoms .

Have a look at this table,

$\boxed{\begin{tabular}{c|1} Atom & Number \\ \cline{1-2}\\ Magnesium (Mg) & LHS=1 \:\: RHS =1\\ \cline{1-2}\\Oxygen(O) & LHS = 2\:\:RHS = 1 \\\end{tabular}}$

So , the equation is not balanced.

On balancing the reaction we get ,

Balanced Equation:

$\purple{\sf{\longmapsto 2Mg+ O_{2}\longrightarrow 2MgO}}$

→ Steps of balancing:

• Multiply 2 to MgO.
• Multiply 2 to Mg.

Again, Have a look at this table,

$\red{\boxed{\begin{tabular}{c|1} Atom & Number \\ \cline{1-2}\\ Magnesium (Mg) & LHS=2\:\: RHS =2\\\cline{1-2} \\Oxygen(O) & LHS = 2\:\:RHS = 2 \\\end{tabular}}}$

So , the equation is now balanced.
