.Which best describes the structure of 2-butene?

A. a four-carbon hydrocarbon with a double bond between the second and third carbon atoms

B. a four-carbon hydrocarbon with a branching point at the second carbon atom in the chain

C. a four-carbon hydrocarbon with a double bond between the first and second carbon atoms​

Answers

Answer 1

Answer:

A.

Explanation:

The 2 - butene is an alkene with the formula C4H8, which can be used as the polybutene monomer or co-polymer. It is a compressed liquefied gas colorless, highly flammable characteristic odor. Prolonged exposure to this gas can cause frostbite causing a lowering of consciousness. Its formula is C4H8 and it is made up of 4 carbon atoms.

The best structure that describes 2-butene is that of Option A.

The distance between an oxygen and hydrogen in a water in 95.98.What is the distance in meter nanometer and centimeters

Answers

Answer:

9.598 × 10⁻¹¹ m

0.09598 nm

9.598 × 10⁻⁹ cm

Explanation:

Step 1: Given data

Distance between oxygen and hydrogen in water (d): 95.98 pm

Step 2: Convert "d" to meters

We will use the conversion factor 1 m = 10¹² pm.

95.98 pm × 1 m/10¹² pm = 9.598 × 10⁻¹¹ m

Step 3: Convert "d" to nanometers

We will use the conversion factor 1 m = 10⁹ nm.

9.598 × 10⁻¹¹ m × 10⁹ nm/1 m = 0.09598 nm

Step 4: Convert "d" to centimeters

We will use the conversion factor 1 m = 100 cm.

9.598 × 10⁻¹¹ m × 100 cm/1 m = 9.598 × 10⁻⁹ cm

Describe how wave frequency changes across the electromagnetic spectrum, from radio waves to gamma rays

Answers

I believe the way it works is the frequency increases as it goes from radio waves to gamma rays, because the energy is increasing.

By increasing the frequency which changes the wavelength,  frequency changes across the electromagnetic spectrum, from radio waves to gamma rays.

What is the electromagnetic spectrum?

The electromagnetic spectrum is a wide range of frequencies that vary depending upon the wavelength of the spectrum and somehow the energy of photons also affects the frequencies and wavelengths.

There are three types of electromagnetic spectrum hydrogen spectrum emission spectrum due to the emission of light and absorption spectrum due to absorption of light.

Therefore, frequency changes across the electromagnetic spectrum, from radio waves to gamma rays are By increasing the frequency which changes the wavelength.

Anatom of an element has no electron,will that atom have any mass or not? Can antom exist
without electron? if so give an example.​

Answers

Answer:

Generally, all atoms of elements contain three sub-atomic particles- Protons(Positively-charged), Neutrons(Neutral) and Electrons(Negatively-charged).

The Magnitude of the Positive Charge possessed by the Protons and the Magnitude of the Negative Charge possessed by the Electrons cancel each other, which make the atom electrically neutral.

Hence,

Without any electrons, the magnitude of the positive and negative charges wouldn't balance, and the atom would be unstable and disintegrate almost immediately. Hence, all stable atoms should have electrons revolving around them, where the number of protons and electrons are the same, under normal conditions.

To Conclude,

Every atom of an element will have electrons arranged in different shells, or matter couldn't exist without electrons.

87.3 atm
46.9 atm
55.5 atm
12 kPa

Answers

Answer:

46.9 atm

Explanation:

Applying Van der waals equation

P = [nRT/(V-nb)]- (an²/V²)............... Equation 1

Where P = pressure, T = temperature, n = number of moles, V = volume, R = Universal constant, a and b = gas constant

Given: n = 20 moles, R = 0.08205 L.atm/mol.K, T = 273 K, V = 10.0 L, a = 0.0341 atm.L²/mol², b = 0.0237L/mol

Substitute these values into equation 1

P = [(20×0.08205×273)/(10-20×0.0237)]-(0.0341×20²/10²)

P = (447.993/9.526)-0.1364

P = 47.028-0.1364

P = 46.9 atm

One major problem with wind and solar energy is that they are conditional. Explain how hydroelectric pumped storage could be used to eliminate this
obstacle? *​
Link to the article https://thinkprogress.org/the-inside story-of-the-worlds-biggest-battery-and-the-future-of-renewable-energy-8984c81283c/

Answers

Answer:

Hydroelectric pumped storage can be used to eliminate the conditional nature of wind and solar energy. At times of peak production of energy from either solar or wind (during summer and windy days), the excess electrical energy produced can be stored using hydroelectric pumped storage methods. When conditions no longer favour energy production from either wind or solar sources, these stored energy can then be regenerated for use.

Explanation:

Pumped-storage hydroelectricity is a type of hydroelectric energy storage used by electric power systems to store excess electrical power during periods of low demand for later release at periods when demand for energy rises again. It stores energy in the form of gravitational potential energy of water, pumped from a lower level reservoir to a higher level reservoir.

At times of low electrical demand, excess generated energy is used to pump water into the upper reservoir. When there is higher demand, water is released back into the lower reservoir through a turbine, generating electricity.

This form of energy storage is useful in circumventing the conditional nature of renewable energy sources such as wind and solar energy. At times of peak production of energy from either solar or wind (during summer and windy days), the excess electrical energy produced can be stored using hydroelectric pumped storage methods. When conditions no longer favour energy production from either wind or solar sources, these stored energy can then be regenerated for use.
