Calcium hydroxide reacts with aluminum sulfate

Chemistry
1 answer:
butalik [34]3 years ago
3 0

Assuming that the complete question is the following:

Calcium hydroxide reacts with Aluminum sulfate to form aluminum hydroxide and calcium sulfate. Write the balanced formula unit equation for the reaction.

Then the balanced formula unit equation would be:

3Ca(OH)₂ + Al₂(SO₄)₃ → 2Al(OH)₃ + 3CaSO₄

This is a double replacement reaction, where the cations and anions are interchanged.

Balancing this reaction is based on the Law of Conservation of Mass, which estates that matter is not created nor destroyed, meaning that the number of atoms at the right and the left of the chemical equation needs to be the same. We add coefficients in front of each species that intervenes in the reaction in order to achieve that equality.

Have a nice day!

Which pair has identical electron configurations?
Thepotemich [5.8K]

Identical electron configurations : K⁺ and Cl⁻

<h3>Further explanation  </h3>

In an atom, there are levels of energy in the shell and sub-shell  

This energy level is expressed in the form of electron configurations.  

Charging electrons in the sub-shell uses the following sequence:  

<em>1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.  </em>

  • S²⁻ and CI

S²⁻ : [Ne] 3s²3p⁶

Cl : [Ne] 3s²3p⁵

  • K⁺ and CI⁻

K⁺ : 1s² 2s² 2p⁶ 3s² 3p⁶

Cl⁻ : 1s² 2s² 2p⁶ 3s²3p⁶

  • S and Ar

S :[Ne] 3s²3p⁴

Ar : [Ne] 3s²3p⁶

  • Cl⁻ and K

Cl⁻ : 1s² 2s² 2p⁶ 3s²3p⁶

K : 1s² 2s² 2p⁶ 3s² 3p⁶4s¹

Answer:

Explanation:

True or false 4 questions help please!

Most mixtures are not physical changes.

True

False   FALSE  when I add solid NaCl salt to water I no longer have a solid salt, I have a solution of sodium and chlorid ions in liquid water.  this is  physical change

Chemical Changes do not create a new substance.

True

False  FALSE 0ne of the proofs that you have a chemical change is the presence of a new substance

Fire is an example of a Chemical Change.

True  TRUE  fire is oxygen reacting wiIh mattter to form new compounds

False

Explosions are not chemical changes.

It depends on the explosion  if I blow up a balloon until it POPS!! that is physical chame.  If I light a firecracker and it explodes, that is a chemical change of oxygen reacting with hot gunpowder

A change in color and odor are both examples of chemical changi

I would rewrite the question as  

A change in color and odor  both INDICATE a chemical change

and that is

True  TRUE

False

F

True   Fire is an example of a Chemical Change.

True

False

Explosions are not chemical changes.

True

False
