QUICK WILL MARK BRAINIEST!!!! The general formula for an acid is (__n ___) where _____ stands for hydrogen, n stands for the ___
Olenka [21]

Answer:

The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).

Explanation:

The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).

An example is H2SO4, also called sulfuric acid

It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2

X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4

1) In the boxes below, draw the model given in the simulation and draw a model of the molecules in an object when the object
sladkih [1.3K]

The molecules of the cold element are going to be closer together and still than the molecules of the hot element because the heat energy causes the molecules to be stimulated and to move.

<h3>How do molecules act at different temperatures?
</h3>

In the image you can see the behavior of the molecules when they are in different environments. On the right you see the cold molecules and on the left the hot molecules that are characterized by the following characteristics:

Cold molecules:

  • Molecules together.
  • Molecules with little movement.

Hot molecules:

  • Separate molecules.
  • Molecules with active movement.

A simple example to understand this behavior of molecules is water because:

  • When water is frozen its molecules are almost static and close together.
  • When the water is liquid and it is heated, the molecules move and that is why the water has bubbles, its molecules are separated.
