Question

a magnesium is burnt in oxygen to give a white compound X accompanied by emission of light ?if the burning ribbon is now placed in an atmosphere of nitrogen it continues to burn and form a compound why?
1) write the chemical formula of X and why ?
2)write the balance chemical equation when X is dissolve in water
​

Answer 1

Explanation:

1) X is magnesium oxide

MgO

2Mg + O2 -> 2MgO

2 )when X is dissolved in water

MgO + H2O -> Mg(OH)2

Answer 2

Answer:

1 magnesium oxide or ash Mg + 02 = Mgo

2 magnesium hydroxide = Mgo + H2o = Mg(OH)2

Explanation:

1 magnesium oxide or ash Mg + 02 = Mgo

2 magnesium hydroxide = Mgo + H2o = Mg(OH)2
