HELP ME I AM DUMB!!!!!!!!!!!!!!!!!!

Write the overall, ionic and net ionic equations for the following reaction.Hydrobromic acid (HBr) and aqueous strontium hydroxide (Sr(OH)2)

Answer 1

The reaction between hydrobromic acid (HBr) and aqueous strontium hydroxide (Sr(OH)2) is a neutralization reaction. The overall chemical equation is HBr(aq) + Sr(OH)2(aq) → SrBr2(aq) + 2H2O(l), and the net ionic equation is 2H+(aq) + 2OH-(aq) → 2H2O(l).

Step-by-step explanation:

The reaction between hydrobromic acid (HBr) and aqueous strontium hydroxide (Sr(OH)2) is a neutralization reaction that produces water and strontium bromide (SrBr2). The balanced overall chemical equation for this reaction is:

HBr(aq) + Sr(OH)2(aq) → SrBr2(aq) + 2H2O(l)

The complete ionic equation shows all of the ions present in solution:

2H+(aq) + 2Br−(aq) + Sr2+(aq) + 2OH−(aq) → Sr2+(aq) + 2Br−(aq) + 2H2O(l)

The net ionic equation only includes the species that are actually involved in the reaction (those that change their state or form new substances) and omits the spectator ions. For this reaction, the net ionic equation is:

2H+(aq) + 2OH−(aq) → 2H2O(l)

Here, 2H+ from the hydrobromic acid and 2OH− from the strontium hydroxide combine to form two molecules of water, which is the net change taking place in this reaction.

Answer 2

2H⁺(aq) + Sr(OH)₂(s) ⟶ Sr²⁺(aq) + 2H₂O(ℓ)

Step-by-step explanation:

You aren't dumb. You just need more time to learn the concepts.

There are three steps you must follow. You must write the:

1. Molecular equation
2. Ionic equation
3. Net ionic equation

1. Molecular equation

2HBr + Sr(OH)₂ ⟶ SrBr₂ + 2H₂O

To predict the states of the substances, we must remember some solubility rules:

• HBr is a strong acid. It dissociates completely in water.
• Most hydroxides are only slightly soluble. Unless the solution is quite dilute, I would write their states in water as "(s)", i.e., a suspension of the solid in water.
• Salts containing Br⁻ are generally soluble.

Acids and bases react to give salts and water.

Thus, the molecular equation is

2HBr(aq) + Sr(OH)₂(s) ⟶ SrBr₂(aq) + 2H₂O(ℓ)

B. Ionic equation

You write all the soluble substances as ions.

2H⁺(aq)+ 2Br⁻(aq) + Sr(OH)₂(s) ⟶ Sr²⁺(aq) + 2Br⁻(aq) + 2H₂O(ℓ)

C. Net ionic equation

To get the net ionic equation, you cancel the ions that appear on each side of the ionic equation.

2H⁺(aq) + 2Br⁻(aq) + Sr(OH)₂(s) ⟶ Sr²⁺(aq) + 2Br⁻(aq) + 2H₂O(ℓ)

The net ionic equation is

2H⁺(aq) + Sr(OH)₂(s) ⟶ Sr²⁺(aq) + 2H₂O(ℓ)
