HELP ME I AM DUMB!!!!!!!!!!!!!!!!!!
densk [106]

Answer:

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

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) + <u>2Br⁻(aq)</u> + Sr(OH)₂(s) ⟶ Sr²⁺(aq) + <u>2Br⁻(aq)</u> + 2H₂O(ℓ)

The net ionic equation is

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

Which of the following compounds will make an electrolytic solution?
Novosadov [1.4K]

Answer: KBr will make an electrolytic solution

Explanation:

Electrolyte is a substance which dissociates into ions when dissolved in water and thus is able to conduct electric current through them.

Compounds in solid form does not conduct electricity due to the absence of free ions.

a) SO_2 is a covalent compound and thus not an electrolyte.

b) C_2H_5OH  is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.

c) KBr  is an ionic compound and thus dissolve in water and give ions which help to conduct electricity.

KBr\rightarrrow K^++Br^-

d) CCl_4  is a covalent compound and thus do not dissolve in water and thus is not an electrolyte.

The term that describes the data that deals with the traits of an object is the term qualitative.

<h3>What is qualitative data?</h3>

The term qualitative data refers to data that is collected from findings that are carried out. It gives the idea of the individual parts of the data that is collected and how it can be accurately used.

It may be pertinent to add that the term "qualitative" come from the word "quality" which has to do with the way in which a thing is or is thought to be. This term is often of very much important when we are dealing with the classification and presentation of data.  

Thus the term that describes the data that deals with the traits of an object is the term qualitative.
