When carbon dioxide is placed in water, aqueous carbon dioxide is formed: 
<h3>Dissolution of compounds in water</h3>
Some compounds are water-soluble, some are just partially soluble, while others are insoluble in water. Some soluble or partially soluble substances dissociate in water into their component ions. These substances are said to be ionic.
Sodium carbonate, like every other sodium salt, is soluble in water. It dissolves in water to form an aqueous solution of sodium carbonate.
While in solution, sodium carbonate dissociates into its component ions according to the following equation:

Carbon dioxide, on the other hand, does not dissociate in water. Instead, it dissolves in water where most of it remains as aqueous carbon dioxide in equilibrium with a small amount of hydronium ion and hydrogen carbonate ion.
Since the hydronium and hydrogen carbonate ions formed are so minute, the equation of the reaction can be written as:

Answer:
I will help? But I don't understand.
Because of the heat, steam
Answer:
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
Explanation:
The formula for for the heat (q) absorbed by an object is
q = mCΔT, where
m = the mass of the sample
C = the specific heat capacity of the sample. and
ΔT = the change in temperature
1. What you must do
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
2. Sample calculation
For this example, I assume that the specific heat capacity of AlF₃ is 1.16 J·K⁻¹mol⁻¹
.
(a) Calculate ΔT

(b) Calculate m
