Answer:
The molecular formula of the ionic compound will be .
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
The molecular formula of the ionic compound will be .
Answer:
(c) 16 m/s²
Explanation:
The position is .
The velocity is the first time-derivative of <em>r(t).</em>
<em /><em />
The acceleration is the first time-derivative of the velocity.
Since <em>a(t)</em> does not have the variable <em>t</em>, it is constant. Hence, at any time,
Its magnitude is 16 m/s².
