Question

a magnesium ribbon is burnt in oxygen to give a white compound 'x' accompanied by emission of light. if the burning ribbon is now placed in the atmosphere of nitrogen it continues to burn and forms a compund 'y'.

(a) write the chemical formula of 'x' and 'y'.

(b) write a balanced chemical equation when 'x' is dissolved in water

Answer 1

hey user here is your answer:

>>> a) the compound 'X' is magnesium oxide , and it's chemical formula is MgO.
the compound 'Y' is magnesium nitrate and it's chemical formula is Mg3N2.

>>>> b) when magnesium oxide is dissolved in water it gives the reaction given below :
MgO + H2O gives Mg(OH)2

hope it helps you!!!!

Answer 2

1) X- MgO

Y- Mg3N2

2) MgO+H2O=Mg(OH) 2
