It’s 5 When u do 1k which is 1000 it’s equal to 0.1 then = 100 which then u do 95 coz that’s a lucky number and u get 5
hi
i did not understood ur question pls clarify and say
bye
Answer:
(<em>n</em> = 7) ⟶ (<em>n</em> = 4)
Explanation:
1. Convert the energy to <em>joules per mole of electrons</em>.
<em>E</em> = 55.1 × 1000 = 55 100 J/mol
2. Convert the energy to <em>joules per electron
</em>
<em>E</em> = 55 100/(6.022 × 10²³)
<em>E</em> = 9.150 × 10⁻²⁰ J/electron
3. Use the Rydberg equation to <em>calculate the transition
</em>
Rydberg's original formula was in terms of wavelengths, but we can rewrite it to have the units of energy. The formula then becomes
where
= the Rydberg constant = 2.178 × 10⁻¹⁸ J
and 
are the initial and final energy levels.
<span>Endothermic Reaction. This reaction or process absorbs energy from its surroundings, mostly, but will not always be, in form of heat. A reaction that requires the input of energy that breaks a bond will always be endothermic. Best examples of endothermic reaction are: 1) melting cubes; 2) evaporating of liquid; 3) melting solid salts, etc.</span>
You can have as many controls as necessary, But they must remain equal at all times in order to get the most accurate results
