Answer:

Eu(ClO3)3

Explanation:

The chlorate ion is written as follows, ClO⁻ ₃. We can see from this that the ion is univalent.

From the formula, Eu203, it is easy to see that the europium ion is trivalent.

Hence, when a compound is formed between the europium ion and chlorate ion, the compound will be written as Eu(ClO3)3.

This is so because, when ionic compounds are formed, there is an exchange of valence between the ions in the compound. This gives the final formula of the ionic substance.

If an object has two forces acting on it how can the next force equal 0
Flura [38]

If the forces are equal and in opposite directions, the net force will equal zero.

Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.

<em>F = ma </em>

The cloth is not moving, so <em>a = </em>0 and the net force <em>F = </em>0.
