9. Based on your work with benzoic acid, show the reaction between salicylic acid and potassium hydroxide. Label the acid, base,

shepuryov [24]

Answer:

Explanation:

Salicylic Acid:

Salicylic Acid is an hydroxy acid that is found as a natural compound in plants. It's IUPAC name is 2-hydroxybenzoic acid. Salicylic acid has an odorless white to light tan solid color. It sinks and mixes very slow with water.

Acid: An acid is a substance that produce hydrogen ion or proton when dissolved in water

Base: A base is a substance that will neutralize an acid to yield salt and water

Conjugate Base: This is a substance formed when an acid loses an hydrogen ion or proton when it dissolved in water.

Conjugate Acid: This is a substance formed when a base accept a proton from from any acid, when it dissolved in water.

Reaction between salicylic acid and potassium hydroxide

HOC₆H₄COOH(aq) + KOH(aq) ⇄ HOC₆H₄COOK(aq) + H₂O(l)

Acid ⇒ HOC₆H₄COOH (salicylic acid)

Base ⇒ KOH (potassium hydroxide)

Conjugate acid ⇒ H₂O (water)

conjugate base ⇒ HOC₆H₄COOK ( 2-hydroxypotasium benzoate)

If a car is traveling 100 km/h and comes to a stop in 3 minutes,what is acceleration of a passenger who is using vehicle restrai

Rama09 [41]

We are given –

Final velocity of car is, v= 0
Initial velocity of car is, u= 100 km/hr
Time taken, t is = 3 minutes or 180 sec

Here–

$\qquad$ $\pink{\bf \longrightarrow Initial\: velocity = 100 \:km/hr}$

$\qquad$ $\sf \longrightarrow Initial\: velocity = \dfrac{ 100 \times 1000}{3600} \:m/s$

$\qquad$ $\pink{ \bf \longrightarrow Initial\: velocity = 27.78\: m/s}$

Now –

$\qquad$ ____________________________

$\qquad$ $\purple{\bf \longrightarrow Acceleration = \dfrac{Final\: Velocity -Initial \:Velocity }{Time}}$

$\qquad$ $\purple{\bf \longrightarrow Acceleration = \dfrac{v -u}{t}}$

$\qquad$ $\sf \longrightarrow Acceleration = \dfrac{(0- 27.78)}{1800}$

$\qquad$ $\sf \longrightarrow Acceleration =\cancel{ \dfrac{- 27.78}{1800}}$

$\qquad$ $\purple{\bf \longrightarrow Acceleration = -0.15 \: m/s^2}$

$\qquad$ _______________________________
