Suppose you have a 0.10 M solution of AlBr3. What is the concentration of each ion? A. 0.10 M Al3+ ions and 0.30 M Br- ions B. 0
podryga [215]

<u>Answer:</u> The concentration of Al^{3+} ions is 0.10 M and that of Br^- ions is 0.30 M

<u>Explanation:</u>

We are given:

Concentration of AlBr_3 = 0.10 M

The chemical equation for the ionization of aluminium bromide follows:

AlBr_3\rightarrow Al^{3+}+3Br^-

1 mole of aluminium bromide produces 1 mole of aluminium ions and 3 moles of bromide ions

So, concentration of aluminium ions = 0.10 M

Concentration of bromide ions = [(3\times 0.1)]=0.3M

Hence, the concentration of Al^{3+} ions is 0.10 M and that of Br^- ions is 0.30 M

The train cars moves in the same direction when the engine car begins

moving to the left.

<h3>What is Law of magnetism?</h3>

The law of magnetism states that like poles repel and unlike poles attract.

In substances which have magnetic field, they are known to attract each

other.

The engine and train car are highly magnetized which results in them

moving in the same direction when they are in close contact with one

another.
