Answer:
a) 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
Explanation:
The energy required to break the bond= energy of the incident photon
E= 941 × 10^3/6.02 × 10^23 = 1.56 ×10^ -18 J
From
E= hc/λ
h= Plank's constant
c= speed of light
λ= wavelength of incident photon
λ= hc/E
λ= 6.6 ×10^-34 × 3 ×10^8/1.56 ×10^ -18 J
λ= 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
Answer:
Number of half lives = 5
Explanation:
Given data:
Half life of oxygen = 2 min
Half lives occured in 10 min = ?
Solution:
Formula;
Number of half lives = Time elapsed / half life
by putting values,
Number of half lives = 10 min / 2 min
Number of half lives = 5

- 1,3,5-Triethylbenzene
<h3>What is IUPAC rule?</h3>
The IUPAC nomenclature system is a set of logical rules devised and used by organic chemists to circumvent problems caused by arbitrary nomenclature.
The 1-ethyl-3-propylcyclopentane molecule contains a total of 30 bond(s) There are 10 non-H bond(s), 3 rotatable bond(s) and 1 five-membered ring(s).
The 1,2-dimethylcyclopentene molecule contains two methyl groups and one double bond in the ring.
The 1,3,5-Triethylbenzene molecule contains three ethyl groups and a benzene ring.
