The distance measured between five successive crests of a wave motion executed by a photon of an electromagnetic radiation is 2.

4cm. what is the frequency of the photon
Chemistry
1 answer:
Jet001 [13]3 years ago
6 0

Answer:

6.25 ×10^10 Hz

Explanation:

If the distance between five successive crests is 2.4 cm, then the distance between each crest is 2.4/5 = 0.48 cm or 0.0048 m or 4.8 ×10^-3 m

Since the velocity of a wave is given by;

v= λf

Where;

λ= wavelength of the wave

f= frequency of the wave

But λ= distance between successive crests = 4.8 ×10^-3 m

v= 3×10^8 ms-1 (speed of electromagnetic waves in vacuum)

f= v/λ

f= 3×10^8 ms-1/4.8 ×10^-3 m

f= 0.625 ×10^11 Hz

f= 6.25 ×10^10 Hz

How many grams of NaOH are produced with the reaction of 5.00 moles of water? *
Andre45 [30]

Answer:

200 grams of NaOH are produced with the reaction of 5.00 moles of water

Explanation:

First of all you apply a rule of three to know the amount of moles of NaOH as follows: if 2 moles of water produce 2 moles of NaOH, 5 moles of water how many moles would they produce?

moles of NaOH=\frac{5 moles of water*2 moles of NaOH}{2 moles of water}

moles of NaOH= 5

Being:

  • Na: 23 g/mole
  • O: 16 g/mole
  • H: 1 g/mole

the molar mass of NaOH is: 23 g/mole + 16 g/mole + 1 g/mole= 40 g/mole

Then a rule of three applies as follows: if in 1 mole there are 40 g of NaOH, in 5 moles how much mass is there?

mass=\frac{5 moles*40g}{1  mole}

mass= 200 g

<u><em>200 grams of NaOH are produced with the reaction of 5.00 moles of water</em></u>

Submit your chart and write a paragraph describing the energy conversions you researched. Remember to proofread your work before
topjm [15]

Answer:

1. Click here to access an interactive simulation where you will explore the transfer and transformations of different types of energy that you have learned about in this lesson.

2. Click the systems box, and then select the energy symbols box. This will allow you to see the movement of energy and its type in the system.

3. Under the bike the person is riding, drag the blue rectangle to the right to start the system.

4. The chemical energy in the person's body is transformed into  

✔ mechanical energy

when they peddle the bike, causing the generator to rotate. Some energy in the bike wheel is lost to  

✔ thermal energy

. The generator produces electricity, which heats the water, causing it to produce thermal energy in the form of steam. When the person's chemical energy runs out, how do you replenish it?  

✔ by feeding them food

5. Change the initial energy source to sun, the intermediate energy source to the solar panel, and the final energy source to the windmill. In this system,  

✔ light energy

is produced from the sun and transformed into electricity in the solar panel. Both of these types of energy are considered forms of  

✔ electromagnetic energy

. The result of this system is that the windmill produces mechanical energy.

6. Try a few more scenarios, choosing different initial, intermediate, and final energy sources. Observe places where energy is transformed and lost. Creating systems with the least amount of energy is important in engineering design.

A cation is a metallic ion derived from base.Why is it derived from base?Can you derive it from an acid?
Scorpion4ik [409]

Answer:the cation can't be drived from an acid

Explanation:

Example

HCL+MgOH2=MgCl2+H2O

The cation in the salt magnesium chloride is magnesium which is derived from the base and the anion chlorine from the acid hydrochloric acid. The same is true in water.

Please can you add as brainleist please!!!!!!!!!!!!!!!!!!!!
