Question

Write word equation when magnesium burns in air.

Answer 1

Answer:

Magnesium + oxygen → magnesium oxide.

mg+o2  --------- mgo2

Answer 2

GiveN :-

• To write the equation when magnesium burns in air .

SolutioN :-

When Magnesium is subjected to burning then it reacts with oxygen present in the air to form Magnesium oxide . The magnesium burns with a dazzling white flame .

The word equation will be :-

$\boxed{\pink{\sf Magnesium + Oxygen \to Magnesium\ oxide }}$

The chemical equation will be :-

$\boxed{\pink{\sf Mg + O_2 \to MgO }}$

When we see at the equation we see that the equation is not balanced . The number of Oxygen in the LHS side is two but there is only one oxygen atom present in the RHS . So lets balance out the equation .

Step 1: Multiplying 2 to MgO on RHS :-

$\sf:\implies \gray{ Mg + O_2 \to \pink{2}MgO }$

Step 2: Multiplying 2 to Mg on LHS :-

$\sf:\implies \gray{ \pink{2}Mg + O_2 \to \pink{2}MgO }$

Hence we balanced out the equation !
