An ionic compound has a highly negative ΔH soln in water. Would you expect it to be very soluble or nearly insoluble in water? E
valina [46]

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.

A certain flexible weather balloon contains 3.5 L of helium gas. Initially, the balloon is in WP at 8500ft, where the temperatur
Advocard [28]

Answer:

\large \boxed{\text{3.9 L}}

Explanation:

We can use the Combined Gas Laws to solve this problem

\dfrac{p_{1}V_{1} }{T_{1}}  =  \dfrac{p_{2}V_{2}}{T_{2}}

Data

p₁ = 571.2 Torr;  p₂ = 400 Torr

V₁ = 3.5 L;          V₂ = ?

T₁ = 21.5 °C;        T₂ = 6.8 °C

Calculations

(a) Convert the temperatures to kelvins

T₁ = (21.55 + 273.15) K = 294.70 K

T₂ =   (6.8  + 273.15) K = 279.95  K

(b) Calculate the new volume

\begin{array}{rcl}\dfrac{p_{1}V_{1} }{T_{1}} & = & \dfrac{p_{2}V_{2}}{T_{2}}\\\\\dfrac{\text{571.2 Torr $\times$ 3.5 L}}{\text{294.65 K}} & = & \dfrac{\text{400 Torr} \times V_{2}}{\text{279.95 K}}\\\\\text{6.78 L} & = & \text{1.429V}_{2}\\\\V_{2} & = & \textbf{4.7 L}\\\end{array}\\\text{The new volume of the balloon is $\large \boxed{\textbf{4.7 L}}$}
