How will an increase in wind speed affect soil erosion?

O A Soil erosion will increase.

O B. Soil erosion will decrease.

O C. Soil erosion will completely stop.

OD Soil erosion will remain the same.​

Answers

Answer:

A. Soil erosion will increase.

Option A is correct. Increase in wind speed will increase the rate of erosion.

The process of eroding, transferring, and depositing tiny particles as well as nutrients from the top layer of soil is known as soil erosion by wind.

In arid and semiarid regions, wind-driven soil erosion is a serious issue that impedes the environmental sustainability of animal husbandry and agriculture and threatens ecological security.

A wind that is blowing at 30 mph will erode at a rate that is more than 3 times faster than a wind that is blowing at 20 mph. As soil moisture rises, wind erosion declines. For instance, dry soil erodes approximately 1.3 times more quickly than soil with just enough moisture to support plant life.

A) pH=pKa+log(0.100.20)

B) pH=pKa+log(0.0050×0.100.0100×0.20)

C) pH=pKa+log[((0.0050×0.10)0.0150)/((0.0100×0.20)−(0.0050×0.10)0.0150)]

D) pH=pKa+log[((0.0050×0.10)+(0.0100×0.20)0.0150)/((0.0100×0.20)−(0.0050×0.10)0.0150)]

Answers

Answer:

C) pH=pKa+log[((0.0050×0.10)0.0150)/((0.0100×0.20)−(0.0050×0.10)0.0150)]

Explanation:

To find the pH of a buffer (The mixture of the weak acid and its conjugate base) we have to use Henderson-Hasselbalch equation:

pH = pKa + log [Base] / [Acid]

Where pKa is the pka of the buffer and [] is molar concentration of the species of the buffer

The [Base] is equal to the concentration of NaOH added:

0.10M * (0.005L / 0.015L)

And the concentration of the acid [Acid] is the initial concentration of the acid - the concentration of the NaOH added:

0.0100L * (0.20M)/0.0150L - 0.10M * (0.005L / 0.015L)

That means the pH of the buffer is:

C) pH=pKa+log[((0.0050×0.10)0.0150)/((0.0100×0.20)−(0.0050×0.10)0.0150)]

A 3mL sample of a 200 Molar solution is left open on a lab
counter for two weeks, after which the concentration of the solution is 6 M. What is the new volume of the solution?

Answers

Answer: New volume of the solution is 100 mL.

Explanation:

Given: [tex]V_{1}[/tex] = 3 mL,     [tex]M_{1}[/tex] = 200 M

[tex]M_{2}[/tex] = 6 M,     [tex]V_2[/tex] = ?

Formula used to calculate the new volume of solution is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\200 M \times 3 mL = 6 M \times V_{2}\\V_{2} = \frac{200 M \times 3 mL}{6 M}\\= 100 mL[/tex]

Thus, we can conclude that new volume of the solution is 100 mL.

orbital.

Answers

Answer: The size of the orbital is determined by the principal quantum number, so the size of the orbital increases as this value increases. Therefore, an electron in a (n-1) orbital is closer to the nucleus than is an electron in a 'n' orbital.

Explanation:

In an atom, the position and energy of an electron is described by a set of numbers and these sets are called quantum numbers.  

There are four quantum numbers. These are as follows.

1). Principal quantum number - This is denoted by "n" and it determines the size and energy of shell in which electron is present. The value of "n" can be 1, 2, 3, and so on but it can never be equal to zero.

2). Azimuthal quantum number - This is denoted by "l" and it determines the shape of an orbital. For s, p, d and f-shell the values of "n" will be 0, 1, 2, 3. The value of l can vary from -n to +n.

3). Magnetic quantum number - This is denoted by "[tex]m_{l}[/tex]." and it determines the orientation of an orbital. The value of ml can vary from -l to +l.

4). Spin quantum number -- This is denoted by "[tex]m_{s}[/tex]" and it determines the spin of an electron. It is independent of the values of n, l and [tex]m_{l}[/tex].

This means that the size of an orbital is determined by principal quantum number. Lower is the value of 'n' (principal quantum number) more closer will be an electron to the nucleus. Hence, more is the value of 'n' more will be the size of nucleus and vice-versa.

For example, an electron present in a 2s-orbital is closer to the nucleus as compared to the electron present in a 3s-orbital.

Thus, we can conclude that the size of the orbital is determined by the principal quantum number, so the size of the orbital increases as this value increases. Therefore, an electron in a (n-1) orbital is closer to the nucleus than is an electron in a 'n' orbital.

Disadvantage: Large-scale accidents can be catastrophic.

Disadvantage: Public perception of nuclear power is negative.

Explanation:

What are the advantages and disadvantages of nuclear energy?

Advantages of nuclear energy:Nuclear energy is safe and emits no greenhouse gases when generating power.Compared to fossil fuels, it is far safer for the general public's health. Compared to the harmful compounds that come from fossil fuels, nuclear waste is not even close to being as dangerous.Nuclear power has a capacity factor that is three times higher than that of wind and solar electricity. Its plants require less maintenance, can run for up to two years without refueling and can produce maximum power more than 93 percent of the time throughout the year.

Disadvantages of nuclear energy:The proliferation of nuclear weapons is the first and currently most discussed drawback of nuclear energy. This discussion was first sparked by the deadly atomic bombings of the Japanese cities of Hiroshima and Nagasaki during the Second World War, and it has recently been reopened due to growing concerns over a nuclear escalation of the conflict between the United States and Russia.Highly dangerous substances like plutonium and the uranium pellets used as fuel are found in radioactive nuclear waste. Despite the fact that accidents are quite unlikely to occur, many people are opposed to nuclear energy because they are aware of the dangers of radioactive waste.One of the most expensive and time-consuming energy sources is nuclear power. The construction of nuclear power plants is extremely expensive and takes a very long period compared to other forms of renewable energy infrastructure, sometimes even more than ten years.

The absorption of infrared (IR) radiation results in vibrations in the molecules or ions that make up a chemical sample. Vibrations cause bond lengths or angles to expand and contract. The energy of infrared radiation (i.e., frequency) required for a vibration depends on the type of bond and the mass of the atoms involved. Typically, the higher the bond order, the stronger the bond, and therefore, the more energy (i.e., higher frequency) required to make the bond vibrate. Also, lighter atoms vibrate at higher frequencies than heavier atoms. The order of vibrational frequencies (from largest to smallest) of the given carbon-nitrogen and carbon-sulfur bonds is

Answers

Answer:

the order of vibrational frequency is:

C ≡ N > C=N > C=S > S-C

Explanation:

The bond's vibration frequency is determined using the following equation:

[tex]\zeta = \dfrac{1}{2 \pi c}\sqrt{\dfrac{k}{\mu}}[/tex]

where;

reduced mass[tex]\mu = \dfrac{m_1m_2}{m_1+m_2}[/tex]

velcoity of light = c

force constant = k

The frequency of vibration, on the other hand, is inversely proportional to the atom's mass, because the heavier the atom, the lower the frequency.

In addition, the value of a bond's stretching frequency rises as the bond's intensity rises. As a result, the frequency is as follows:

triple > double > single

The reduced mass [tex](\mu)[/tex] of C-N bond.

[tex]\mu = \dfrac{m_1m_2}{m_1+m_2}[/tex]

[tex]\mu = \dfrac{12*14}{12+14} \\ \\ \mu = 6.46[/tex]

The reduced mass of C-S bond;

[tex]\mu = \dfrac{m_1m_2}{m_1+m_2}[/tex]

[tex]\mu = \dfrac{12\times 32}{12+32} \\ \\ \mu = 8.72[/tex]

Thus, the order of vibrational frequency is:

C ≡ N > C=N > C=S > S-C

20.00 mL of a 0.077 M solution of silver nitrate, AgNO3, is mixed with 30.00 mL of a 0.043 M solution of sodium acetate, NaC2H3O2. Does a precipitate form? The Ksp of AgC2H3O2 is 2.5*10^-3.

Answers

Answer:

No, no precipitate is formed.

Explanation:

Hello there!

In this case, since the reaction between silver nitrate and sodium acetate is:

[tex]AgNO_3(aq)+NaC_2H_3O_2(aq)\rightarrow AgC_2H_3O_2(s)+NaNO_3(aq)[/tex]

In such a way, we can calculate the concentration of silver and acetate ions in the solution as shown below, and considering that the final total volume is 50.00 mL or 0.0500 L:

[tex][Ag^+]=\frac{20.00mL*0.077M}{50.00mL}=0.0308M[/tex]

[tex][C_2H_3O_2^-]=\frac{30.00mL*0.043M}{50.00mL}=0.0258M[/tex]

In such a way, we can calculate the precipitation quotient by:

[tex]Q=[Ag^+][C_2H_3O_2^-]=0.0308*0.0258=7.95x10^{-4}[/tex]

Which is smaller than Ksp and meaning that the precipitation does not occur.

A compound has the following percentages by mass: barium, 58.8%; sulfur, 13.74%; oxygen, 27.43%. Determine the empirical formula.​

Answers

Answer:

BaSO₄

Explanation:

Let's assume we have 100 g of the compound. If that's the case we would have:

58.8 g of Ba13.74 g of S27.43 g of O

Now we convert the masses of each element into moles, using their respective molar masses:

58.8 g Ba ÷ 137.327 g/mol = 0.428 mol Ba13.74 g S ÷ 32 g/mol = 0.429 mol S27.43 g O ÷ 16 g/mol = 1.71 mol O

We divide those moles by the lowest number among them:

0.428 mol Ba / 0.428 = 10.429 mol S / 0.428 ≈ 11.71 mol O / 0.428 = 4

We can express those results as Ba₁S₁O₄, meaning the empirical formula is thus BaSO₄.

Each one is a unique subterranean environment that may include enormous chambers, tight tunnels, underground rivers and waterfalls, unique animals, or other natural wonders. It's no surprise that humans throughout history have explored caves. The recreational sport of exploring caves is known as caving or spelunking. Anyone can enjoy caving, which offers adventurous experiences for all levels. In the United States, more than one hundred caves are open to the public. People can explore them by participating in guided tours or by following marked paths. This is a great way to get started with caving and to experience the sport firsthand. Those seeking more adventure can join caving clubs to learn advanced caving skills and connect to others who share their passion. The National Speleological Society sponsors over two hundred caving clubs in the United States. These clubs organize excursions to caves that are not open to the public, and advanced spelunkers may even get the chance to explore parts of caves that have never been seen before. Caving clubs also promote conservation; as a general rule, people should never leave anything behind in caves, never take anything out, and never damage any rock formations. Caving requires special equipment. For example, it is very important to have a source of light when exploring a dark cave. Cavers need to wear a well-fitted helmet with a headlamp. Back-ups for light sources, which can include extra batteries, flashlights, and glow sticks, are also important. Caves often get cold and can be very wet, so rugged, waterproof clothing, including sturdy hiking boots, is recommended. Other items to bring include enough food and water for the excursion, a small first aid kit, and a map of the cave. Caving can be a very safe sport when participants are well informed, cautious, and prepared. No one should explore a cave alone; it is best to explore in small groups of four to six people, and every expedition should have a
