Answer: completely (100%) dissociates, producing a significant amount of H+ and OH- ions in solution, making it conduct electricity well.
Explanation:
A strong acid is one that ionizes or dissociate completely in water to yield its hydrogen ion (H+) as the only positively charged ion.
For example: Hydrochloric acid (HCl) dissociates completely in water to give hydrogen ion and chlorine ion
HCl(aq) --> H+(aq) + Cl-(aq)
A strong base, on the other hand, dissociates completely in water to yield an hydroxyl ion (OH-) as the only negatively charged ion. A good example is Sodium hydroxide NaOH
NaOH (aq) --> Na+(aq) + OH-(aq)
And since mobile and charged ions help transmit electric current, a strong acid or base produces significant amount of H+ and OH- ions that conduct electricity well.
Answer: -
37.5 g of NaCl are in 250 g of a 15.0% (by weight) solution.
Explanation: -
Total mass = 250 g
Percentage of NaCl = 15.0 %
= 
Thus 
= 
Number of grams of NaCl present = 
= 37.5 g
Answer:
6.Given,
Final Velocity =60m/s
Initial Velocity= 0
Time=10 sec
A=?
A=Final Velocity- Initial Velocity/time
=60-0/10
=60/10
=6m/s ans.
Explanation:
Acceleration = Final Velocity - Initial Velocity/Time
By using this Formula we can calculate Acceleration.
