Best Answer: o.n. = 70 means 70% isoctane for which o.n. = 100 and 30% of heptane for which o.n. = 0
Answer:
B
Explanation:
solute is what gets dissolved in the solvent
ie: salt in water. salt is the salute and the more of it you add to the water (solvent) the more interactions will occur increasing rate
I'm pretty sure brewed coffee :)
The trend of electronegativity in the periodic table is increasing from left to right and from bottom to top. In the period 4 which is horizontal, the element which has the highest electronegativity is the right most element except the noble gas. This element is bromine.
The wavelength is obtained as 122 nm. Option A
<h3>What is the wavelength?</h3>
We know that from the Bohr model of the atom, an electron can move from a higher energy level to a lower energy level or from a lower energy level to a higher energy level. This is the idea of energy quantization as put forward by Neill Bohr.
The wavelength can be obtained by the use of the formula;
1/λ = RH(1/n^2initial - 1/n^2 final)
λ = wavelength of the emitted light
RH = Rydberg's constant
n intial = initial energy level
nfinal = final energy level
Thus;
1/λ = 1.09 * 10^7(1/1^2 - 1/2^2)
1/λ = 1.09 * 10^7( 1 - 0.25)
λ = 122 nm
