Answer:

c. 2NH₃ + 2H₂O  + Cu²⁺ → Cu(OH)₂(s) + 2NH₄⁺

Explanation:

A net ionic equation is a chemical equation that list only the species that are involved in the reaction.

The reaction of ammonia with copper(II) sulfate CuSO₄ in water is:

2NH₃ + 2H₂O  + CuSO₄ → Cu(OH)₂(s) + 2NH₄⁺ + SO₄²⁻

In an ionic equation, salts are written as ions, that means CuSO₄ must be written as Cu²⁺ + SO₄²⁻. That is:

2NH₃ + 2H₂O  + Cu²⁺ +<u> SO₄²⁻</u> → Cu(OH)₂(s) + 2NH₄⁺ + <u>SO₄²⁻</u>

As in a net ionic equation you must list only the species involved in the reaction (The underlined species don't react), the net ionic equation is:

<em>c</em>. <em>2NH₃ + 2H₂O  + Cu²⁺ → Cu(OH)₂(s) + 2NH₄⁺</em>

<em></em>

I hope it helps!

The image is a model of sulfuric acid that has a chemical formula of H2SO4.
gladu [14]

Models help us to understand the properties of molecules and help us to predict the kind of reactions they undergo.

A molecular model is a three dimensional representation of a molecule. Usually, molecular models could either be;

  • Ball and stick models or
  • Space filling models.

In either case, the model gives us a vivid representation of the molecule and enables us to predict its properties and reactivity based on the the inter-connectivity of atoms in the structure as shown in the model. The model of H2SO4 as shown gives us an idea of its properties and its reactivity.

You are trying to determine how
ss7ja [257]

Answer:

0,218 moles

Explanation:

I will first explain how many liters is 256ml, that is 0,256 l.

because the m stands for milli which is a factor of 1000 -> (256 ml / 1000 = 0,256 l)

To calculate the amount of moles you multiply the volume with the concentration. So 0,256l x 0,855M = 0,218 moles.
