what is Brownian motion​

Answers

Answer: the erratic random movement of microscopic particles in a fluid, as a result of continuous bombardment from molecules of the surrounding medium. Brownian motion, or pedesis, is the random motion of particles suspended in a medium. This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain. Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for the Scottish botanist Robert Brown, the first to study such fluctuations (1827).

Determine the number of hydrogen atoms in an alkyne with one carbon–carbon triple bond and 4 carbon atoms.
number of hydrogen atoms: ?

Answers

Answer:

There are 6 hydrogen atoms.

Explanation:

The formula for an alkyne that has only one triple bond is as follows:

CₙH₂₍ₙ₎₋₂

Where n is any natural number greater than 2.

For this problem, n=4. This would mean the formula is:

C₄H₂₍₄₎₋₂

Thus

C₄H₈₋₂C₄H₆

Thus the answer is 6, there are 6 hydrogen atoms.

Write the balanced chemical equation between H2SO4 and KOH in aqueous solution. This is called a neutralization reaction and will produce whater and potassium sulfate. Phases are optional.
0.650 L of 0.430 M H2SO4 is mixed with 0.600 L of 0.240 M KOH. What concentration of sulfuric acid remains after neutralization?

Answers

Answer:

0.166M

Explanation:

In a neutralization, the acid, H₂SO₄, reacts with a base, KOH, to produce a salt, K₂SO₄ and water. The reaction is:

H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

To solve this problem, we need to determine moles of H2SO4 and moles of KOH that reacts to find the moles of sulfuric acid that remains after the reaction:

Moles H2SO4:

0.650L * (0.430mol /L) = 0.2795moles H2SO4

Moles KOH:

0.600L * (0.240mol / L) = 0.144 moles KOH

Moles of sulfuric acid that reacts with 0.144 moles of KOH are:

0.144 moles KOH * (1mol H2SO4 / 2 mol KOH) = 0.072 moles of H2SO4 react.

And remain:

0.2795moles H2SO4 - 0.072moles H2SO4 = 0.2075 moles of H2SO4 reamains.

In 0.650L + 0.600L = 1.25L:

Molar concentration of sulfuric acid:

0.2075 moles of H2SO4 / 1.25L =

0.166M

What is the mass % of acetone in a 1.77 M solution of acetone (MM = 58.08 g/mol) in water? The density of the solution is 0.971 g/mL.

Answers

Answer:

[tex]\%m/m=10.6\%[/tex]

Explanation:

Hello!

In this case, since the by-mass percent is defined by:

[tex]\%m/m=\frac{m_{solute}}{m_{solution}} *100\%[/tex]

Thus, since the given 1.77 M solution is given in terms of mol/L, we need to compute the mass of acetone via its molar mass and the volume of solution in L to g via the density:

[tex]\%m/m=1.77\frac{mol}{L}*\frac{58.08g}{1mol}*\frac{1L}{1000mL}*\frac{1mL}{0.971g} *100\%\\\\\%m/m=10.6\%[/tex]

Each of the structures for CIOCI, NCOH, and CINO has atoms connected in the order given in their formulas. Identify the type of hybridization for the central atom in each compound. Write the appropriate items to their respective bins.
a. nitrogen in CINO
b. oxygen in CIOCI
c. carbon in NCOH
1. sp
2 sp2
3. sp3

Answers

Answer:

see explanation

Explanation:

If we look at the structures of each of the compounds we can be able to deduce the accurate hybridization of each of the atoms listed.

Looking at ClNO - we can see that the nitrogen atom is linked to oxygen by a double bond and linked to chlorine by a single bond retaining a lone pair on nitrogen. Hence the nitrogen is in sp2 hybridized state.

For ClOCl, the compound has a sp3 hybridized oxygen atom linked to two chlorine atoms as expected retaining two lone pairs on oxygen.

For NCOH, the carbon atom is doubly bonded to oxygen hence it is sp2 hybridized.

Answer:

A) Label 2 (Sp2)

B) Label 3 (Sp3)

C) Label 1 (Sp)

Explanation:

A) Have 7 Lone Pairs (LP) to place. 1 on N. 1 becomes a double bond. Double bonds count as 1 Electron Group. Same for single bond and LP. Add these to get 3. 3 coresponds for SP2

B) 8LP. 2LP on O. 2 bonds to O. Add to get 4. 4-> Sp3

C) 5LP. C O bond is double. single bond to N. Add to get 2-> Sp

How much water would need to be added to 1092 mL of a 54.7 M NaCl solution to make a 0.25 M solution?

Answers

Answer:

237.8L of water would need to be added.

Explanation:

The first thing to do is to identify that the equation to be used is M1V1=M2V2. (This equation works because it turns everything into moles which can then be compared).

Then figure out what information you have and what is being found. In this case:

M1 = 54.7 M

V1 = 1092 mL = 1.092 L

M2 = 0.25 M

V2 = unknown

Then solve the equation for whatever you are trying to find.

M1V1=M2V2

V2=M1V1/M2

Now you need to plug everything in.

V2=(54.7M*1.091L)/0.25M

V2=238.93L

That means that the solution needs a volume of 238.7L to gain a molarity of 0.25M but the starting solution already had a volume of 1.092 L meaning that to find the amount of solvent that needs to be added you just subtract the starting volume by the volume that the solution needs to be.

238.93L - 1.091L = 237.8L

Therefore the answer is that 237.8L needs to be added to a 1.092L 54.7M NaCl solution to make the concentration 0.25M.

I hope this helps.  Let me know if anything is unclear.

A sample of TNT, C-H5N306, has 7.30 1021 nitrogen atoms. Determine the numbers of
hydrogen atoms in this sample of TNT.
021​

Answers

Answer:

1.22 × 10^22 H atoms

Explanation:

From this question, TNT has the chemical formula: C-H5N306. The number of nitrogen atoms in the TNT substance is said to be 7.30 × 10^21 atoms.

The number of hydrogen atoms in the same TNT substance can be got using mole ratio. Based on the chemical formula, the mole ratio of hydrogen to nitrogen is 5:3 i.e. H5N3.

This means that;

Number of atoms of hydrogen = 5/3 of the number of atoms of nitrogen.

Hence, number of H atoms = 5/3 × 7.30 × 10^21

number of H atoms = (7.30 × 5/3) × 10^21

number of H atoms = (36.5/3) × 10^21

number of H atoms = 12.1666 × 10^21

number of H atoms = 1.2166 × 10^22 atoms.

Approximately, number of H atoms in TNT is 1.22 × 10^22 atoms.

.What does the changing the Aperture do when taking a photo? *
4.What effect can you get from using a slow shutter speed? *
5.What effect can you create by using a quick shutter speed?

Answers

Answer:

Slower shutter speeds like 1/60 second and slower cause a blurring effect. If you want to take a picture using a slow shutter speed, it is best to mount the camera on a tripod and use image stabilization (such as SteadyShot® technology) to reduce the chance of any unwanted camera movement.

The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. ... If you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past.

What is a chemical equation?

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

How to balance the equation

Ag₂O —> Ag + O₂

There are 2 atoms of O on the right side 1 on the left. It can be balance by writing 2 before Ag₂O as shown below

2Ag₂O —> Ag + O₂

There are 4 atoms of Ag on the left side and 1 atom on the right side. It can be balance by writing 4 before Ag as shown below

2Ag₂O —> 4Ag + O₂

Two waves were analyzed with some high-tech instrumentation. The first wave was found to have a wavelength of 3 x 10 m and the second wave had a wavelength of 3 x 10 m. Which wave would have a higher frequency? Explain​

Answers

Explanation:

The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m

We need to find which wave have a higher frequency.

The relation between frequency and wavelength is given by :

[tex]c=f\lambda[/tex]

Let f₁ and f₂ be the frequency of wave 1 and wave 2.

[tex]f_1=\dfrac{c}{\lambda_1}\\\\f_1=\dfrac{3\times 10^8}{3\times 10^5}\\\\=1000\ Hz[/tex]

And

[tex]f_2=\dfrac{c}{\lambda_2}\\\\f_2=\dfrac{3\times 10^8}{3\times 10^4}\\\\=10000\ Hz[/tex]

Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.
