Answer:
A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum. The color of flames in general also depends on temperature; see flame color.

I hope it's help u ;)
That water is a universal solvent and that sugar is soluble?
Opp that that person has to correct answer
We are given that:
100 mL total solution with 1:50 povidone iodine solution
This means that there is 1 mL of povidone iodine solution
per 50 mL of total solution. Since we are given a total of 100 mL solution,
therefore we have an initial amount of:
pure povidone iodine solution = 2 mL
This amount of pure povidone iodine solution is added or
diluted (most perhaps with water) to make a total of 1000 mL total solution,
therefore the new ratio is:
2:1000 povidone iodine solution
By dividing both sides by 2, this simplifies to
1:500 povidone iodine solution
Answer:
1:500
Hello!
We have the following data:
f (radiation frequency) = 
v (speed of light) = 
λ (wavelength) = ? (in m)
Let's find the wavelength, let's see:
I Hope this helps, greetings ... DexteR! =)
