place when Magnesium ribbon
is burnt? 2. What is left after
the Magnesium ribbon
completely burns? Write its
chemical name. 3. What will
happen when water is added
to the burnt magnesium? 4.
What will happen if we put a
red litmus paper in this
solution? Give reason. 5. Why
should you not see the
burning magnesium ribbon for
long?
note :- please answer correct ​

Answer 1

Explanation:

1, exothermic reaction takes place when magnesium ribbon is burnt.

2, precipitate of magnesium oxide is left after burning the magnesium ribbon.

3,it turns milky white.

4,the red litmus paper turns blue .it shows that MgO is basic in nature

Answer 2

Answer:

a combination reaction takes place.Mg2 + o2 =2mgo

2.solid white magnesium oxide powder is left as residue

3. chemical name is magnesium oxide MgO

4. as on adding water following reaction will take place\

MgO+h20= Mg(OH)2

this solution is basic in nature and turns red litmus blue.

5. amount of light released by flame can be harmful for eyes and damage them.

hope it helps...
