Answer:
C. Mass relationships
Explanation: hope this helped
Answer : The concentration of
ion is 
Explanation :
First we have to calculate the moles of
.

The balanced chemical reaction will be:

From the reaction we conclude that,
1 mole of
dissociate to give 3 moles of
ion and 1 mole of
ion
So,
0.03 mole of
dissociate to give
moles of
ion and 0.03 mole of
ion
Now we have to calculate the concentration of
ion.


Therefore, the concentration of
ion is 
Answer:they are used to generate sound waves in the ultrasonic range
Explanation:transducers are used to generate sound waves in the ultrasonic range ,by turning electrical energy into sound
Five. Even if you also specified
l
=
2
, it would not make a difference.
A "FORCE" is required to cause acceleration or cause an object to move.
