Answer:

hexagonal layers slide

Explanation:

The layers in graphite can slide over each other because the forces between them are weak. The delocalised electrons are free to move through the structure, so graphite can conduct electricity.This makes graphite slippery, so it is useful as a lubricant .

<em>i think it's right</em>

hope it helps :)

Write the balanced NET ionic equation for the reaction when chromium(III) bromide and sodium phosphate are mixed in aqueous solu
Mariulka [41]

The balanced NET ionic equation for the reaction is CrBr₃(aq) + Na₃PO₄(aq) ==> CrPO₄(s) + 3NaBr(aq)

<h3>What is a balanced Ionic equation ?</h3>

In a balanced ionic equation, the number and type of atoms are the same on both sides of the reaction arrow.

Additionally, the net charge is the same on both sides of the equation.

Separate into the complete ionic equation.

It should be obvious that the aquous solutions ionize and the solid is shows as the molecule since it doesn't dissolve.

Cr³⁺(aq) + 3Br⁻(aq) + 3K⁺(aq) + PO₄³⁻(aq) ==> CrPO₄(s) + 3K⁺(aq) + 3Br⁻(aq)

Now look and cancel those ions common to both sides. What is left is the net ionic equation.

Cr³⁺(aq) + PO₄³⁻aq) ==> CrPO₄(s)
