Explain in a short sentence how you can tell if a reaction is a double replacement<br> reaction.
Monica [59]

Explanation:

In a double displacement reaction, there is an actual exchange of partners to form new compounds.

The reaction is given as shown below:

         AB + CD →  AD + CB

One of the following conditions serves as the driving force for a double replacement reaction:

  • Formation of an insoluble compound or precipitate
  • Formation of water or any other non-ionizing compound
  • Liberation of a gaseous product.

What is the mass of 4.56 moles of copper (ii) fluoride​
musickatia [10]

Answer:

463.0 g.

Explanation:

  • We can use the following relation:

<em>n = mass/molar mass.</em>

where, n is the mass of copper(ii) fluoride​ (m = 4.56 mol),

mass of copper(ii) fluoride​ = ??? g.

molar mass of copper(ii) fluoride​ = 101.543 g/mol.

∴ mass of copper(ii) fluoride​ = (n)(molar mass) = (4.56 mol)(101.543 g/mol) = 463.0 g.
