What mass of Ba3(PO4)2 is contained in 1575 mL of a 0.35M solution of Ba3(PO4)2
LekaFEV [45]

Answer:

= 331.81 g

Explanation:

Molarity is calculated by the formula;

Molarity = Moles/volume in liters

Therefore;

Moles = Molarity ×Volume in liters

          = 0.35 M × 1.575 L

          = 0.55125 Moles

But; Molar mass of Ba3(PO4)2 is 601.93 g/mol

Thus;

Mass = 0.55125 moles × 601.93 g/mol

         <u>=331.81 g</u>

The following drawing is a representation of a reaction of the type A → B, where different shaded spheres represent different mo
Alex73 [517]

Answer: The given reaction is non-spontaneous at low temperatures and spontaneous at high temperatures.

Explanation:

We know that relation between free energy and enthalpy is as follows.

             \Delta G = \Delta H - T\Delta S

As in the given drawing, solid is converting into gas. This means that there is occurring an increase in entropy of the system. This also means that the enthalpy change will also be positive.

Free energy change is negative (spontaneous) at high temperature and free energy change is positive at low temperature.

Hence, we can conclude that the given reaction is non-spontaneous at low temperatures and spontaneous at high temperatures.

Indicate the type of solute-solvent interaction that should be most important in each of the following solutions.a. LiCl in wate
topjm [15]

Explanation:

a. LiCl is an ionic molecule whereas water is a polar molecule with net dipole moment in it. There LiCl in water would have an ion-dipole force of interaction.

b. Both NF3 and CH3CN have dipole moment in them, since both are polar molecule. Hence, there would be dipole-dipole interaction.

c. Here both CCl4 and benzene are non polar molecules therefore, they have London dispersion force of interaction.

d. In methylamine and water both have hydrogen bonding in them. The nitrogen of CH3NH2 forms hydrogen bond with water.
