Which conclusion is consistent with the following net ionic equation? co2+(aq) + s2-(aq) cos(s)
PolarNik [594]

The conclusion that is consistent with the ionic equation would be that COS (s) is a precipitate.

<h3>What is a precipitation reaction?</h3>

It is a reaction in which 2 soluble salts in aqueous forms react to produce an insoluble salt as one of the reaction's products.

Precipitate products are usually insoluble and can be filtered off using suitable filter paper. In other words, they are solids that are suspended in solution.

Following the ionic reaction, the two reacting ions are in aqueous forms while the product formed is solid.

Why are ionic solids poor conductors of electricity
marshall27 [118]

Answer:

Ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier”.

Hope this helps :)

Convert to moles:<br> 100.0g Ca3(PO4)2
salantis [7]

Answer:

0.322 moles

Explanation:

Given Mass, m = 100 g

The molar mass of Ca₃(PO₄)₂

Ca₃(PO₄)₂ = (3 x 40.08) + (2 x 30.97) + (8 x 16.00)

M = 310.18 g/mol

Let there are n number of moles,

n = given mass/ molar mass

n=\dfrac{100 }{310.18 }\\\\n=0.322\ mol

So, there are 0.322 moles.
