Answer:
wavelength = 0.534×10⁻¹⁶ m
Explanation:
Given data:
Frequency of wave = 5.62 ×10²⁴ Hz
Wavelength = ?
Solution:
Speed of photon = wavelength × frequency
wavelength = speed of photon / frequency
Now we will put the values in formula:
wavelength = 3×10⁸ m/s / 5.62 ×10²⁴ Hz
Hz = s⁻¹
wavelength = 3×10⁸ m/s / 5.62 ×10²⁴ s⁻¹
wavelength = 0.534×10⁻¹⁶ m
Molar mass RbMnO₄ = 204.40 g/mol
1 mole ---------- 204.40 g
7.88 mole ------ ?
mass = 7.88 * 204.40 / 1
mass = 1610.672 g
hope this helps!
Answer:
Explanation:
A Brönsted-Lowry acid is defined as any substance that has the ability to lose, or "donate a proton" [H +].
A Brönsted-Lowry base is a substance capable of gaining or "accepting a proton" [H +].
Then a proton transfer occurs, which requires the presence of a proton donor, that is, an acid and a base that accepts them.
This theory has the disadvantage of leaving out several substances that are acidic and that do not have protons.
Thiocyanic acid is a chemical compound that can be considered, but not a Bronsted Lowry base, giving up the proton and generating the anion [SCN] -

<u>Answer:</u>
The very early discovery of particles that were subatomic was proposed by Dalton, which was then negated by the postulates suggested by Thomson that proved Dalton's theory.
<u>Explanation:</u>
The structural arrangement of atoms were approved by Thomson and Rutherford using the technique of air condition in x-ray showing the arrangement of protons and neutrons within Centre.
A nucleus and the negative particles that we called electrons moving around which were also shown to be much lighter than the particles present in the centre.
