The ionic compound will be soluble in water.
Ions are present in ionic compounds, which are held together by the attraction interactions between the ions with opposing charges. One of the most well-known ionic compounds is table salt or sodium chloride. Molecular compounds are made up of separate molecules that are connected by sharing electrons (covalent bonding).
High melting points are found in ionic substances. ionic compounds are brittle and rigid. When an ionic chemical is dissolved in water, it separates into ions. Ionic compound solutions and melting forms of these substances carry electricity, while solid materials do not.
A substance's heat of solution value is one of the criteria that determine whether or not it will dissolve. The Ionic compound will dissolve in water because a negative heat of the solution indicates that the reaction will be spontaneous.

<u>Answer:</u> The number of moles of gas present are 0.390 moles
<u>Explanation:</u>
To calculate the number of moles of gas, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 0.868 atm
V = Volume of the gas = 11 L
T = Temperature of the gas = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
R = Gas constant = 
n = number of moles of gas = ?
Putting values in above equation, we get:
Hence, the number of moles of gas present are 0.390 moles
