Answer 1

its C because i just anwserd it & it was right

Answer 2

Answer:

The molecular formula of the ionic compound will be $Na_2O$.

Explanation:

The ratio of Na to O is 2:1

This means that for every two atoms of sodium there are 1 atom of oxygen.Then the molecular formula will be:

Let the number of sodium atom be 2x and oxygen atom be x

$Na_{2x}O_x=Na_2O$

The molecular formula of the ionic compound will be $Na_2O$.
