If we fill up a balloon with just helium gas, it will only contain helium atoms.
Time taken = 3 hours
<h3>Further explanation</h3>
Given
speed : 75 mph
distance : 225 miles
Required
time taken
Solution
An equation of constant velocity motion
d = distance = m
v = speed = m / s
t = time = seconds
Input the value :
t = d : v
t = 225 miles : 75 miles/hour
t = 3 hours

Less than that of nitrogen and oxygen remember cnof "see noff" . this is the order of electronegativity carbon is less than nitrogen which is less than oxygen which is less than fluorine.
Explanation:
This situation is analogous to a double replacement reaction. A double-replacement reaction occurs when parts of two ionic composites are exchanged, making two new composites. One characteristic of this kind of reaction is that there are two compounds as reactants and two different compounds as products. So, in this case we can relate with it because there are two new couples with the same members that formed the previous couples.
