Just did the test.
Answer is "An egg cooking".
I thought it was a candle burning because it keeps going until the light goes out but was wrong :( lol.
Hope this helps!
The lines occurring in an emission spectrum are all electromagnetic waves, which means that their speed in a vacuum is
3 x 10⁸ m/s
We can use the equation,
v = fλ
which relates the velocity of a wave to the frequency and wavelength. Substituting values,
3 x 10⁸ = f * 434 x 10⁻⁹
f = 6.91 x 10¹⁴ Hz
The frequency of the wave will be 6.91 x 10¹⁴ oscillations per second.
Please let me know when you find out, i need this question answered as well
Answer: 4000000000
because 20X200000000=4000000000
To answer this question, you need to know the chemical equation for making glucose. It should be look like this
C6H12O6<span>(s) + 6O2(g) -->6CO2(g) + 6H2O(g)
In the equation, the amount of glucose (</span>C6H12O6) is 1 and the amount of oxygen(O2) is 6. But the equation ratio is using moles as a unit. A mole of glucose will weight 180g but a mole of oxygen weight 32g.
Then, the amount of oxygen forms would be: 6/1 * (15.90g/180g) * 32g= 16.96 grams
