What is the frequency of a red light with a wavelength of 6.98 x 10^-6

Chemistry

nevsk [136]3 years ago
4 0

Answer:

frequency of light = 4.2\times 10^{-13}

Explanation:

we know that relation between frequency and wavelength of light is

frequency × wavelength = speed of light.

therefore frequency = \frac{c}{wavelength}

                                  = \frac{3\times 10^{8}}{6.98\times 10^{-6}}

                                  =4.2\times 10^{-13}

Polymers are large molecules composed of simple units repeated many times. Thus, they often have relatively simple empirical for
sp2606 [1]

Answer:

(a) C5H8O2

(b) C2H2Cl2

(c) CH2

(d) CH

Explanation:

We need to find the proportion of the atoms in whole numbers. Given the percentages we can calculate the number of moles and find their proportions.

Assume 100 g and given the atomic weights the moles are calculated.

(a) C = 59.9/ 12.01 = 4.98  ≈ 5.00

    H = 8.06/1.007 = 8.00

    O = 32/15.999  = 2.00

C5H8O2

(b) C= 24.8/12.01 = 2.06≈ 2.00

    H = 2.0/1.007 = 1.99 ≈ 2.00

   Cl = 73.1/ 35.453 = 2.06 ≈ 2.00

C2H2Cl2

(c) C = 86/12.01 = 7.16  

    H= 14/1.007 = 13.90

7.16:13.90 ≈ 1:2

CH2

(d) C = 92.30/12.01 = 7.68

    H = 7.7 / 1.007 =   7.65

7.68:7.65 ≈ 1:1

CH

Crude oil is a liquid kind of what?
Afina-wow [57]

Answer:

Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon), though it also contains some nitrogen, sulfur, and oxygen. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified.
