Liquids and solids are referred to as “condensed phases” because the attractive forces are?

Answers

leave little space between the molecules.

Explanation:

Condensed phase means that there is less space between the molecules of a matter. And a condensed phase do not compress easily so basically, they resist compression.

For example, solids and liquids are both condensed phases as there is less space between their particles and hence they are closer as compared to particles of a gaseous phase.

Though they have fixed volume but both of them are resistant to compression.

Therefore, we can conclude that liquids and solids are referred to as “condensed phases” because the attractive forces leave little space between the molecules.

A sample of fluorine gas exerts a pressure of 900 mmHg. When the pressure is changed to 1140 mmHg, the volume is 250 mL. What was the original volume?

Answers

Let's use Boyle's Law here. P1*V1 = P2*V2
Given: (assuming that there are decimals at the end for Sig Figs)
P1 = 900.mmHg
P2 = 1140.mmHg
V1 = ???
V2 = 250.mL

900.mmHg* ??? = 1140.mmHg * 250.mL
??? = 1.27*250.mL
??? = 318.mL

Therefore, the original volume is 318mL.

A 50.0-mL sample of a 1.50 M NaOH solution is titrated with a 2.90 M HCl solution. What will be the final volume (sample + titrant) of solution when the NaOH has been completely neutralized by the HCl?

Answers

Final answer:

To neutralize a 50.0-mL sample of a 1.50 M NaOH solution with a 2.90 M HCl solution, you need 25.86 mL of HCl. Thus, the final volume of the solution when the NaOH has been completely neutralized by the HCl is 75.86 mL.

Explanation:

First, you need to calculate the amount (moles) of NaOH in your original solution. To do this, multiply the volume of your solution (in liters) by the molarity. This yields (50.0 mL / 1000 mL/L) x 1.50 mol/L = 0.075 mol NaOH.

Next, use the balanced neutralization reaction between HCl and NaOH:

HCl (aq) + NaOH (aq) → H2O (l) + NaCl (aq)

From this reaction, we can see that one mole of HCl reacts with one mole of NaOH to produce one mole of water and one mole of sodium chloride.

Given that you have 0.075 moles of NaOH, you will need an equivalent amount of HCl for neutralization. Knowing the concentration of your HCl solution (2.9 M), calculate the volume of HCl required using the formula:

Volume = moles / molarity = 0.075 mol / 2.90 mol/L = 0.02586 L or 25.86 mL of HCl.

The final volume of the solution is ultimately the sum of the original NaOH solution volume and the volume of HCl titrant added: 50.0 mL + 25.86 mL = 75.86 mL.

silver tarnishes when it comes into contact with hydrogen sulfide in the air.

physical property or chemical property

Answers

This would be classified as a chemical change.

Final answer:

Silver tarnishing is a chemical property, as it involves a reaction between silver and hydrogen sulfide in the air to form silver sulfide. This process alters the composition of the silver, differentiating it from physical properties.

Explanation:

The tarnishing of silver is a result of a chemical reaction between silver and hydrogen sulfide in the air. When silver tarnishes, it essentially reacts with hydrogen sulfide gas to form a compound called silver sulfide, which has a dark, streaky black appearance. The chemical equation for this reaction is 2 Ag(s) + H₂S(g) → Ag₂S(s) + H₂(g). This tarnish is not simply a surface dirt or residue that can be washed off, but a fundamental change in the surface layer of the silver object itself, which is why tarnishing is considered a chemical property.

The formation of silver sulfide (tarnish) indicates a change in the composition of the silver item, which differentiates this chemical property from physical properties that do not involve a change in chemical composition. Physical properties can include melting point, density, or color in a physical state, whereas chemical properties involve the substance's ability to undergo a specific chemical change. In this context, the tarnishing of silver aligns with other chemical properties such as the ability of iron to rust or for substances to burn, rot, explode, decompose, or ferment.

Now, to calculate [tex]\Delta G[/tex], the equation used is:

[tex]\Delta G=\Delta H-T\Delta S[/tex]

We are given:

[tex]\Delta H=-559170J\\T=298K\\\Delta S=-573.91J/K\\[/tex]

Percent Yield is the actual practical yield of a certain chemical reaction. It is always less than the theoretical yield calculated due to human handling and error.

Percent Yield = (Actual yield / theoretical yiield) * 100 = (0.456 / 0.800) * 100 = 57%

The yield here is small which means a bad handling and high error.

Answer:

The percent yield is 58.12 %.

what is the difference between cytokinesis and mitosis

Answers

Mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature while Cytokinesis is the process where the cytoplasm of the cell divides to form two cells. 
Final answer:

Mitosis and cytokinesis are two processes in the cell division cycle. Mitosis refers to the division of the cell nucleus and occurs before cytokinesis. Cytokinesis is the final step that divides the cell into two separate daughter cells.

Explanation:

Mitosis and cytokinesis are two crucial processes in the cell division cycle. Mitosis refers to the division of the nucleus, where the contents of the nucleus get divided equitably and distributed between its two halves. This process is divided into four major stages: prophase, metaphase, anaphase, and telophase.

 Cytokinesis, however, occurs after mitosis and is the process that divides the cell's cytoplasm and body into two separate cells, becoming the final step in the cell division process. In animal cells, this usually begins during the late anaphase and involves a contractile ring composed of actin filaments. For plant cells, which have cell walls, the process is a bit different.

So basically, mitosis is the process by which the cell nucleus divides, whereas cytokinesis is the process that completes cell division by splitting the cell itself into two new cells.

Answers

This is a case of metric system of measurements. The scale of the metric system only differs by a factor of 10. The scale (from greatest to least) is kiloliter, hectoliter, dekaliter, liter, deciliter, centiliter and milliliter. If the unit is 150 dL, and you want to find the equivalent dkL measurement, just move the decimal point 2 decimals places to the left (just follow the scale). The same procedure is done for the other metric units.

150 dL = 1.5 dkL
150 dL = 15 L
150 dL = 1,500 cL
150 dL = 15,000 mL

From the choices, the answer is letter C.

Final answer:

The correct answers are C) 1,500 centiliters (cL) and D) 150,000 milliliters (mL) because both equal 150 deciliters (dL) after conversion.

Explanation:

The student's question asks which of the following measurements is equal to 150 deciliters (dL): A) .015 dekaliters (daL), B) 0.15 liters (L), C) 1,500 centiliters (cL), or D) 150,000 milliliters (mL). Converting these options to deciliters will help us find the correct answer:

Option A: 0.015 daL is equal to 1.5 dL (because 1 daL = 10 dL).Option B: 0.15 L is equal to 15 dL (because 1 L = 10 dL).Option C: 1,500 cL is equal to 150 dL (because 1 cL = 0.1 dL).Option D: 150,000 mL is equal to 150 dL (because 1,000 mL = 1 L and 1 L = 10 dL).

So, both options C and D are correct. They both equal 150 dL when converted.

Answers

Hey there! 

Number of moles = 2.22 moles

Volume of solution = 1.5 L

Therefore:

M =  n / V

M = 2.22 / 1.5

=> 1.5 M

Answer C

To find the molarity of the HCl solution, divide the number of moles of HCl (2.22) by the volume of the solution (1.5 L), which results in a molarity of 1.48 M. This is rounded to 1.5 M to match the closest given answer option.

The question is asking you to calculate the molarity of the HCl solution when 2.22 moles of HCl are dissolved in 1.5 liters of water. Molarity (M) is defined as the number of moles of solute (in this case HCl) divided by the volume of the solution in liters. To calculate the molarity, follow these steps:

Write down the known values: moles of HCl (moles) = 2.22 moles, volume of solution (V) = 1.5 L.

Use the molarity formula: M = moles/V.

Calculate molarity: M = 2.22 moles / 1.5 L = 1.48 M.

Since molarity has to be reported to correct significant figures, and given options do not include 1.48 M, we round to the closest given option, which is 1.5 M (C).
