What impact does LED light have on the environment?

Chemistry
1 answer:
Lapatulllka [165]3 years ago
5 0

Answer:

Hi, here's the answer

LED bulbs consume less power per unit (lumen) of light emitted.

This reduces greenhouse emissions from power plants.

Carbon dioxide emissions for LEDs are also low.

Roughly, one LED bulb will minimize greenhouse gas emissions by almost half a ton

A microwave operates at 7.42 mm wavelength. How much energy is produced in Joules from 359 photons?
alisha [4.7K]

Answer:

E=9.62\times 10^{-21}\ J

Explanation:

Given that,

The wavelength of a microwave is 7.42 mm or 0.00742 m

No. of photons, n = 359

We need to find the energy produced by this no of photons. It can be given by the formula as follows :

E=\dfrac{nhc}{\lambda}\\\\E=\dfrac{359\times 6.63\times 10^{-34}\times 3\times 10^8}{0.00742}\\\\=9.62\times 10^{-21}\ J

or

E=9.62e^{-21}\ J

So, the required energy is 9.62\times 10^{-21}\ J.

Write a balanced half-reaction for the product that forms at each electrode in the aqueous electrolysis of the following salts:(
likoan [24]

Balanced Half reactions are:

At anode 2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}

At Cathode:  2H^{+} + 2e^{-} ==> H₂

Since the question states that you are using an aqueous solution of MnCl₂,  so ions will have present are, H₂O, H^{+}, Mn^{2+} and Cl^{-}

Now at Anode reaction will occur as given:

2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}  (will occur)

At Cathode:

2H^{+} + 2e^{-} ==> H₂ (will occur)

At Cathode:

Mn^{2+} +  2e^{-}==> Mn (This reaction will not occur)

The deposition of solid Mn will not occur because in aqueous solution, H^{+}will be reduced before Mn^{2+} .

The reduction potentials for H^{+} is zero whereas reduction potential for Mn^{2+} is - 1.18V.

The reduction potential of a species is its tendency to gain electrons and get reduced. It is measured in millivolts or volts. Larger positive values of reduction potential are indicative of a greater tendency to get reduced.
