Select the compound that is most likely to increase the solubility of ZnSe when added to water.NaCnMgBr2NaClKClO4
vlada-n [284]

Answer:

NaCl.

Explanation:

In the solution, ZnSe ionizes to Zn^2^+ and Se^2^- . Following reaction represents the ionization of ZnSe in solution -

ZnSe ⇄ Zn^2^+ + Se^2^-

As we want to increase the solubility of ZnSe, we must decrease the concentration of dissociated ions so that the reaction continues to forward direction.

If we add NaCl to this solution, then we have Na^+ and Cl^- in the solution which will be formed by the ionization of NaCl.

Now, Zn^2^+ in the solution will react with two Cl^- ions to form ZnCl_2 as follows -

Zn^2^++2Cl^- ⇄ ZnCl_2

Due to this reaction the concentration of Zn^2^+ will decrease in the solution and more ZnSe can be soluble in the solution.

A saturated solution of calcium hydroxide contains 1.85 g of solute in 100. mL of solution. What is its molarity
Leona [35]

Answer:

M=0.250M

Explanation:

Hello!

In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution in liters, we first need to compute the moles of solute knowing that the molar mass of calcium hydroxide is 74.1 g/mol as follows:

n=1.85g*\frac{1mol}{74.1g}=0.0250mol

Next, since the 100-mL solution is also expressed in liters by 0.100 L, we directly compute the molarity as shown below:

M=\frac{0.0250mol}{0.100L}\\\\M=0.250M

Which is expressed in molar units that are mol/L.

Best regards!

Answers:

1. B.)

2. Both A.) and B.)

3. A.)

Step-by-step explanation:

1. Ions in gas phase

A plasma is a gas consisting of electrons and positively charged ions.

Because the particles are ions and electrons, rather than neutral atoms or molecules as in ordinary gases, scientists consider a plasma to be a fourth state of matter<em>.</em>

2. Kinetic Molecular Theory

Both activities illustrate the postulate.

A.) If the particles are extremely small and far apart, most of the volume of a gas is empty space. That's why it's easy to push the plunger of a capped nozzle syringe containing a gas.

B.) If the particles are far apart, it's easy for a coloured gas to spread into an inverted jar placed on top of a jar containing the gas.

3. Hot air balloon

The high temperature in the balloon makes the gas molecules spread apart according to Charles's law, because this law describes how a gas will behave at constant pressure.

As the hot air escapes from the vent, the combined mass of balloon + hot air becomes less than the mass of cold air that it displaces, and the balloon rises.

B.) is <em>wrong</em>. Boyle's law applies only when both the number of moles and  the temperature remain constant.
