Answer : The number of moles of carbonate ion, (CO_3^{2-}) produced are, 0.207 moles.

Explanation : Given,

Moles of sodium carbonate = 0.207 mol

As we know that when sodium carbonate dissolved in water then it dissociates to give 2 sodium ion and 1 carbonate ion.

The balanced chemical reaction will be:

Na_2CO_3(aq)\rightarrow 2Na^+(aq)+CO_3^{2-}(aq)

From the balanced chemical reaction we conclude that,

As, 1 mole of sodium carbonate dissociate to give 1 moles of carbonate ion, (CO_3^{2-})

So, 0.207 mole of sodium carbonate dissociate to give 0.207 moles of carbonate ion, (CO_3^{2-})

Thus, the number of moles of carbonate ion, (CO_3^{2-}) produced are, 0.207 moles.

In general, what is the effect if increased temperature on the solubility of a gas
r-ruslan [8.4K]

Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution.
