How many fluoride ions (f-1) are needed to balance an aluminum ion (al+3)?

The correct answer is that we need three fluoride ions (F-1) to balance the compound.

Explanation:

Hello!

Let's solve this!

For the compound to be balanced, the charges have to be balanced.

We have +3 loads of Al and -1 of F.

We must multiply by 3 the Fluor so that it is as follows:

+ 3 + 3 * (- 1) = + 3-3 = 0

Therefore, we conclude that the correct answer is that we need three fluoride ions (F-1) to balance the compound.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
