That is when one substance changes into one or more new substances, it has exhibited a chemical change.
A Chemical change is a change that takes places when a substance changes its composition by forming one or more new substances. As here also, one substance is changing into one or more new substance, thus it exhibits a chemical change.
Answer:
λ = 5.68×10⁻⁷ m
Explanation:
Given data:
Energy of photon = 3.50 ×10⁻¹⁹ J
Wavelength of photon = ?
Solution:
E = hc/λ
h = planck's constant = 6.63×10⁻³⁴ Js
c = 3×10⁸ m/s
Now we will put the values in formula.
3.50 ×10⁻¹⁹ J = 6.63×10⁻³⁴ Js × 3×10⁸ m/s/ λ
λ = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 3.50 ×10⁻¹⁹ J
λ = 19.89×10⁻²⁶ J.m / 3.50 ×10⁻¹⁹ J
λ = 5.68×10⁻⁷ m
There are four major components found in wood, and these
are:
cellulose
lignin
starch
protein
Among the four, I believe that cellulose and lignin are
the most difficult to degrade because they contain large amount of cross-linked
heavy hydrocarbons.
Answer:
cellulose
lignin
