What is the concentration of hydronium ion in a 0.121 M HCl solution?

kogti [31]

Answer:

C) 0.121 M

Explanation:

HCl + H₂O = H₃O⁺ + OH⁻

.121M .121M

HCl is a strong acid . It will dissociate almost 100 % so the concentration of acid and hydronium ion formed will be equal . It is to be noted that hydronium ion is formed due to association of H⁺ and H₂O . H⁺ is formed due to ionisation of HCl .

So concentrtion of hydronium ion ( H₃O⁺ ) will be .121 M.

When Arti kicks a football, two forces interact. Arti's foot exerts a force of 5N on the ball. What size force will be exerted o

Papessa [141]

A size force of 5N will be exerted on Artl's foot.

This is because Newton's third law of motion, where in which an action occurs, a reaction will occur with the same amount of force, but reversed towards the direction of the area where the action occurred.
