Answer:

0.895V

Explanation:

The emf of an electrochemical cell is obtained from the Nernst equation as shown in the images attached. The emf of an electrochemical cell is read from voltmeter in the circuit. The Nernst equation is used to obtain the emf of cell when it is not operated under standard conditions. That is the concentration of solutions is not 1M, temperature is not 25oc and pressure (for gases is not 1ATM)

An aqueous solution is saturated with both a solid and a gas at 5 ∘c. what is likely to happen if the solution is heated to 85 ∘

denpristay [2]

<span>When the aqueous solution is heated to 85âC, the gas entrapped in the aqueous solution is released since the vapour pressure of the particular entrapped gas is more than the solution. The solid saturated in the aqueous solution returns back to its original form once the aqueous solution evaporates. A good example is that of the salt left behind after heating a brine solution to evaporate.</span>

Answer:

1. There are 7 categories:

Radio waves, microwaves, infrared heat waves, visible light spectrum, ultraviolet waves, x-rays, gamma rays

2. They are all electromagnetic radiation.

3. The amount of energy the photons within them have.

4. The longer the wavelength, the less energy. The shorter the wavelength, the more energy. They are inversely proportional.

5. As the wavelength increases, the smaller the frequency. The shorter the wavelength, the larger the frequency. They are inversely proportional. Also, wavelength is measured in meters and frequency is measured in hertz (cycles per second). They are two of the 3 ways EM radiation is expressed.

6/7 Reds have the least. Violets have the most.

8. Violet has the shortest. Red has the longest.

9. Ultra Violet B-Rays (UV-B) are the harmful rays that cause sunburn.

10. Microwaves are generally used for radar technology.

11/12 You are exposed to all of the categories of the electromagnetic spectrum everyday of every year. You just can't see/feel them all.

hope this helps! stay happy and healthy, friend! :))
