5. The point at which the relative humidity reaches 100% is the
and (2 points)
the air can hold no more water vapor.

Answers

Answer 1

The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form.

Answer 2

Answer:

ii cud givee uu an explanation for understandment for help if still don't understand im sowwyy thenn.

Explanation:

relative humidity is related to the partial pressure of water vapor in the air at 100% humidity the partial pressure is equal to the vapor pressure and no more water can enter the vapor phase.

A 17.5 mL portion of a 0.1050 M Na2CO3 solution is added to 46.0 mL of 0.1250 M NaCl. What is the concentration of sodium ion in the final solution?

Answers

The sodium ion concentration in the solution of 17.5 mL of 0.1050 M Na₂CO₃ and 46.0 mL of 0.1250 M NaCl is 0.148 M.

To find the Na⁺ concentration in the final solution, we need to find the number of moles of the ion in the Na₂CO₃ and NaCl solutions and the volume of the final solution.  

[tex] C_{Na^{+}} = \frac{n_{t}}{V_{t}} [/tex]  (1)

Where:

[tex] n_{t} [/tex]: is the total number of moles of Na⁺

[tex] V_{t} [/tex]: is the volume of the final solution

The number of moles of Na⁺ in the Na₂CO₃ solution

The number of moles of Na₂CO₃ can be calculated as follows:

[tex] n_{Na_{2}CO_{3}} = C_{Na_{2}CO_{3}}*V_{Na_{2}CO_{3}} [/tex]

Where:

[tex] C_{Na_{2}CO_{3}} [/tex]: is the concentration = 0.1050 mol/L

[tex] V_{Na_{2}CO_{3}} [/tex]: is the volume = 17.5 mL = 0.0175 L

[tex] n_{Na_{2}CO_{3}} = 0.1050 mol/L*0.0175 L = 1.84 \cdot 10^{-3} \:moles [/tex]

We can find the number of moles of Na⁺ knowing that in 1 mol of Na₂CO₃ we have 2 moles of Na⁺.

[tex] n_{Na^{+}} = \frac{2 \:mol\: Na^{+}}{1\:mol \:Na_{2}CO_{3}}*mol \:Na_{2}CO_{3} = \frac{2 \:mol\: Na^{+}}{1\:mol \:Na_{2}CO_{3}}*1.84 \cdot 10^{-3} \:moles = 3.68 \cdot 10^{-3} \:moles [/tex]

The number of moles of Na⁺ in the NaCl solution

The number of moles of Na⁺ in the NaCl solution is:

[tex] n_{NaCl} = C_{NaCl}*V_{NaCl} = 0.1250 mol/L*0.046 L = 5.75 \cdot 10^{-3} \:moles [/tex]

In 1 mol of NaCl we have 1 mol of Na⁺, so the number of moles of Na⁺ in the NaCl solution is 5.75x10⁻³ moles.

Total number of moles of Na⁺

The total number of moles of Na⁺ in the final solution can be calculated as follows

[tex] n_{t} = n_{{Na^{+}}_{Na_{2}CO_{3}}} + n_{{Na^{+}}_{NaCl}} = 3.68 \cdot 10^{-3} \:moles + 5.75 \cdot 10^{-3} \:moles = 9.43 \cdot 10^{-3} moles [/tex]

Hence, the number of moles of Na⁺ in the final solution is 9.43x10⁻³ moles.

The volume of the final solution

The volume of the final solution is given by:

[tex] V_{t} = V_{Na_{2}CO_{3}} + V_{NaCl} = 0.0175 L + 0.046 L = 0.0635 L [/tex]

Concentration of Na⁺ in the final solution

The concentration of Na⁺ in the final solution is (eq 1):

[tex] C_{Na^{+}} = \frac{n_{t}}{V_{t}} = \frac{9.43 \cdot 10^{-3} moles}{0.0635 L} = 0.148 mol/L [/tex]

Therefore, the concentration of sodium ions in the final solution is 0.148 M.

What makes physical change a physical change and a chemical change a chemical change

Answers

A physical change is any change in a substances form that does not change its chemical makeup. Examples of physical changes are breaking a stick or melting ice. A chemical change occurs when atoms of a substance are rearranged, and the bonds between the atoms are broken or formed. HOPE THIS HELPS!!

Answer:

A physical change is reversible and the changes made are only physical (smell, physical state, volume, etc) and most importantly no new substance is formed. In a chemical change, a new substance is formed, the chemical properties are changed, and it's permanent.

0.250 moles of NaCl is dissolved in 0.850 L of solution. What is the molar concentration?

Answers

Considering the definition of molarity, the molar concentration is 0.294 [tex]\frac{moles}{liter}[/tex].

Molarity reflects the concentration of a solution indicating the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

[tex]molarity=\frac{amount of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case, you know:

amount of moles of solute= 0.250 molesvolume= 0.850 L

Replacing in the definition of molarity:

[tex]molarity=\frac{0.250 moles}{0.850 L}[/tex]

Solving:

molarity= 0.294 [tex]\frac{moles}{liter}[/tex]

Finally, the molar concentration is 0.294 [tex]\frac{moles}{liter}[/tex].

Suggest an alternative to zinc oxide that could react with hydrochloric acid to give you the desirable product.(1 mark)

Answers

Crystallization, followed by filtration to remove excess solution, followed by drying on a watch glass or in a warm oven, can yield pure dry crystals of zinc chloride.

What is crystallization?

Crystallization is defined as the formation of a solid in which the atoms or molecules are highly organized into a structure known as a crystal.

It can also be defined as a natural process that occurs when materials solidify from a liquid or precipitate from a liquid or gas.

There are basically three types of crystallization.

Evaporative crystallizationCooling crystallization from solution or the meltReactive crystallization or precipitation

Filtration is defined as the process of removing solid particles from a liquid or gaseous fluid by using a filter medium that allows the fluid to pass through but retains the solid particles.

Zinc oxide that could react with hydrochloric acid to give you the desirable product because acid is a neutralizing base, the reaction of hydrochloric acid with zinc oxide to form zinc chloride and water is a neutralization reaction .

Thus, crystallization, followed by filtration to remove excess solution, followed by drying on a watch glass or in a warm oven, can yield pure dry crystals of zinc chloride.
