Answer:
Pretty sure they're both A.
ANSWERS:
They are both ionic compounds.
These compounds are made up of 
cations (positively-charged ion) and either 
or 
anions (negatively-charged ions).
Their names both end in -ic acid.
Acids are named based on their anion. With acids like these where the anion is attached to a hydrogen cation, we name such acids with the the suffix “-ic”.
They both contain polyatomic ionic.
and are both polyatomic ions.
"Poly-" = many
"ions" = have a + or - charge
So, yes, these are ions that are made up of several atoms (not just one atom like )
10
In one molecule of N2H4 (Hydrazine), there are two nitrogen atoms.
So, to find how many there are in five molecules, multiply by five.
2 x 5 = 10
With the given information we can calculate instatenous speed and average speed
To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.
Average speed = Distance / time
Velocity = displacement/time
Displacement. = v × t
