Explanation:
Answer:
The acronym is used to remember evidence of a chemical change.
Explanation:
P=precipitate
U=unexpected color change
F=fizzing
A=aroma
R=replaced by a new substance
T= temperature change
The Bohr model is an inaccurate model because there is no way to measure the exact position or location of an electron in an atom.
Answer:
pH = 2.5
Explanation:
Given data:
Concentration of HBr = 0.003 M
pH of solution = ?
Solution:
Formula:
pH = -log[H⁺]
by putting values,
pH = -log [ 0.003]
pH = 2.5
The increasing order of photons in terms of energy is Er < Ey < Eb
A photon is a tiny particle of electromagnetic radiation and its energy is proportional to the frequency and rest mass as zero.
By using the formula:
E = h * ν
E = h * c / λ
h = planks constant
c = speed of light
Since h * c is constant
E is inversely proportional to wavelength λ
For blue:
λ = 453 nm
Eb= k / 453
where k is constant
For red:
λ = 660 nm
Er = k / 660
For yellow:
λ = 595 nm
Ey = k / 595
Therefore,
The increasing order of photons in terms of energy is
Er < Ey < Eb.
