Answer:

Crude oil is a mixture of hydrocarbons

Explanation:

Crude oil is a fossil fuel composed mainly of hydrocarbons, compounds that contain carbon and hydrogen mainly in their molecular structure. Crude oil can also contain small amounts of sulfur, nitrogen and oxygen. It is formed under conditions of high pressure and heat by the transformation of organic matter.

As mentioned, oil is made up of hydrocarbons. And the number of carbon atoms and the way they are placed inside the molecules of the different compounds gives the oil different physical and chemical properties.

So, <u><em>crude oil is a mixture of hydrocarbons</em></u>.

An electromagnetic wave that has a lower frequency than infrared radiation will have ____ than the infrared radiation. longer wa

Monica [59]

Answer: longer wavelength and lower energy.

Explanation:

1) The wavelength is inversely related to the frequency. So, an electromagnetic wave with lower frequency will have longer wavelength.

This is the formula for electromagnetic waves:

λ = c / ν

where λ is the wavelength, c is the speed of light, and ν is the frequency.

2) Energy is directly related to the frequency.

This is the formula E = hν,

where E is the energy, h is Planck constant, and ν is the frequency.

So, the lower the frequency the lower the energy.

3) Conclusion:
<span>An electromagnetic wave that has a lower frequency than infrared radiation will have longer wavelength and lower energy than the infrared radiation</span>

silver has an atomic mass of 107.868 amu. silver has two common isotopes. one of the isotopes has a mass of 106.906 amu and a re

Sunny_sXe [5.5K]

A. The abundance of the 2nd isotope is 48.119%

B. The mass of the 2nd isotope is 108.905 amu

Let the 1st isotope be A

Let the 2nd isotope be B

A. Determination of the abundance of the 2nd isotope

Abundance of isotope A = 51.881%.

<h3>Abundance of isotope B =? </h3>

Abundance of B = 100 – A

Abundance of B = 100 – 51.881

<h3>Abundance of B = 48.119%</h3>

B. Determination of the mass of the 2nd isotope

Atomic mass of silver = 107.868 amu.

Mass of 1st isotope (A) = 106.906 amu

Abundance of isotope A (A%) = 51.881%.

Abundance of isotope B (B%) = 48.119%

<h3>Mass of 2nd isotope (B) =? </h3>

$atomic \: mass = \frac{mass \: of \:A \times \:A\%}{100} + \frac{mass \: of \:B \times \:B\%}{100} \\ \\ 107.868 = \frac{106.906\times \ \: 51.881}{100} + \frac{mass \: of \:B \times \:48.119}{100} \\ \\ 107.868 = \: 55.464 + 0.48119 \times mass \: of \:B \\ \\ collect \: like \: terms \\ \\ 0.48119 \times mass \: of \:B = 107.868 - 55.464 \\ \\ divide \: both \: side \: by \: 0.48119 \\ \\ mass \: of \:B = \frac{107.868 - 55.464 }{0.48119} \\ \\ mass \: of \:B =108.905 \: amu \\ \\$

Therefore, the mass of the 2nd isotope is 108.905 amu

Complete these equations for the ionization of an Arrhenius acid or base in water. Include the states of the products.

Mazyrski [523]

1)
HI(aq) → H⁺(aq) + I⁻(aq)
So this is an Arrhenius acid because it releases H⁺.

2)
LiOH(s) → Li⁺ + OH⁻
So this is an Arrhenius base because it releases OH⁻

d1i1m1o1n [39]

Answer:

Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground.

Explanation:

For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.
