To determine the most likely charge of the Wr ion in stable ionic compounds, we need to consider its position in the periodic table. Since Wr has an atomic number of 119, it belongs to the hypothetical element of the eighth period, which means it is a superheavy element that has not been discovered yet.

Currently, the highest atomic number element that has been synthesized is Oganesson (Og) with atomic number 118. Elements with such high atomic numbers are highly unstable and undergo rapid radioactive decay. It is unlikely that an element with atomic number 119, like Wr, would be stable.

Therefore, we cannot assign a specific charge to the Wr ion since it does not exist currently. However, if Wr were to form an ion in a hypothetical stable compound, it would likely follow the trends in the periodic table. Typically, elements in group 1 (alkali metals) lose one electron to form a +1 ion, while elements in group 2 (alkaline earth metals) lose two electrons to form a +2 ion. However, since Wr has a much higher atomic number, it is difficult to predict its behavior accurately.

Moving on to writing a balanced equation for the reaction of Wr with water, since the behavior of Wr is unknown, we cannot accurately predict its reaction with water. However, we can provide a general equation assuming Wr behaves similarly to other alkali metals and alkaline earth metals:

Wr + H2O -> Wr(OH)x + H2

In this equation, Wr reacts with water to form Wr hydroxide (Wr(OH)x) and hydrogen gas (H2). The value of 'x' would depend on the actual behavior of Wr and cannot be determined without further information.

Assuming Wr reacts to form a carbonate compound, we can write the formula for the compound between Wr and the carbonate ion, CO32–. Since Wr's behavior is unknown, we can only provide a hypothetical formula:

WrCO3

In this hypothetical compound, Wr combines with the carbonate ion to form a carbonate compound.

As for its solubility in water, it is difficult to predict without specific knowledge about Wr's behavior and the nature of its interactions with carbonate ions. However, we can generally say that most carbonate compounds are insoluble in water, with a few exceptions such as alkali metal carbonates (group 1 elements) and ammonium carbonate (NH4)2CO3. This is because carbonates are generally basic and tend to form insoluble precipitates with many metal ions in water. Therefore, it is likely that Wr carbonate would also be insoluble in water, but this is purely speculative based on general trends in chemistry.
