Energy is related to Wavelength as,
E = h c / λ -------- (1)
As,
h = 6.626 × 10⁻³⁴ Js
c = 2.99 × 10⁸ ms⁻¹
λ = 12.5 nm = 1.25 × 10⁻⁸ m
Putting values in eq. 1,
E = (6.626 × 10⁻³⁴ Js × 2.99 × 10⁸ ms⁻¹) ÷ 1.25 × 10⁻⁸ m
E = 1.585 × 10⁻¹⁷ J
E = 1.585 × 10⁻²⁰ kJ × 6.022 × 10²³
E = 9544.87 Kj/mol
<u>Answer</u>:
the law of conservation of mass is valid for all the following, except nuclear reactions.
<u>Explanation</u>:
the law of conservation of mass is valid for all the following, except nuclear reactions because some mass gets converted to energy.
Answer:
it's because aluminium is a ductile material
Answer:
Chiral:
3-Methyl-2-butanol
Achiral:
1-Pentanol
3-Pentanol
3-Methyl-1-butanol
Explanation:
Only the molecule that bears a carbon atom surrounded by 4 different groups can be said to be Chiral, the other molecules don't satisfy this property.
I would say C. Since the material is getting warmer, the atoms and molecules will start to move fasten and then also create more "messiness" (which is entropy with a less-nice word)
