Answer:A. Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.

C. Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.

D. The contents of the half-cell module should be disposed of in the waste container in the hood.

Explanation: An electrochemical cell is a cell that has the capability of producing Electric energy from chemical reaction (voltaic cells) or using Electric energy to make chemical reactions to take place(electrolytic cell). For a proper or effective waste disposal in an electrochemical cell the following options are correct.

Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.

Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.

The contents of the half-cell module should be disposed of in the waste container in the hood.

Draw the structural formula of the major product of the reaction of (S)-2,2,3-trimethyloxirane with MeOH, H . Use the wedge/hash
Katarina [22]

Answer:

(S)-3-methoxy-3-methylbutan-2-ol

Explanation:

In this case, we have an <u>epoxide opening in acid medium</u>. The first step then is the <u>protonation of the oxygen</u>. Then the epoxide is broken to generate the most <u>stable carbocation</u>. The nucleophile (CH_3OH) will attack the carbocation generating a new bond. Finally, the oxygen is <u>deprotonated</u> to obtain an ether functional group and we will obtain the molecule <u>(S)-3-methoxy-3-methylbutan-2-ol</u>.

See figure 1

I hope it helps!

Describe the difference between red light and blue light. Describe the difference between red light and blue light. 700 nm corre
fiasKO [112]

Answer:700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range.

Explanation:The wavelengths of the visible spectrum are usually between 400 nm and 700 nmn with the the rays of red light having a longer wavelength, and blue light rays having shorter wavelengths. The red light has a low frequency of about 405–480 THz and , blue light has a higher frequency in the range of 620–680 THz.  This is due to the inverse relationship between wavelength and frequency which also occurs betwwn  wavelength and energy of light rays with the  red light having less photon energy of about  1.65–2.00 eV and the  blue light with high energy photons of about 2.64–2.75 eV.

Red light can be employed in the photosynthesis in plants as it helps in formation of flowers and the production of fruits. Blue light also is important in the production of chlorophyll and can cause a healthy and strong stem and leaves in excess exposure.
