Question

an element x burns in air to form an oxide. this oxide reacts with dilute sulphuric acid to form a salt. a.what kind of oxide is formed by element x? b.what does this tell you about element x? c. how can you show that the oxide formed is basic or acidic?

Answer 1

X is a metal as only metals turn into oxides, which are alkaline and thus neutralize acid like dilute sulphuric acid.

Hey friend!
The answers are...
a. the element is basic in nature
b. the element is a metal because metallic oxides are generally basic in nature.
c. the oxide reacts with acid to produce a salt. This is possible only when the oxide is basic.
