Bumek [7]

Answer:- 2AuClO_4(aq) + CaBr_2(aq)\rightarrow 2AuBr(s)+ Ca(ClO_4)_2(aq)

Explanations:- It's a double replacement reaction where a precipitate of silver(I)bromide is formed. A dpuble replacement reaction in general looks as AB + CD \rightarrow AD + CB

To balance the equation we need to multiply gold compounds on both sides by 2 and the balanced equation is..

2AuClO_4(aq) + CaBr_2(aq)\rightarrow 2AuBr(s)+ Ca(ClO_4)_2(aq)

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)

An ionic bond can be formed when one or more electrons are:
Mashutka [201]
D - for example, Potassium has 1 electron on its outer shell, whilst Chlorine has 7 electrons on its outer shell. Potassium loses one electron to Chlorine so that each of them have a full outer shell. This would form Potassium Chloride.
