The balls are not perfectly elastic, but the main reason is probably air.
Explanation:
When 2 adjacent balls have any distance between them, there is air in the space. When the moving neighbor comes at a stationary ball the moving ball has to push the air out of the way.
I hope this helps
1.Start with the number of grams of each element, given in the problem.
2.Convert the mass of each element to moles using the molar mass from the periodic table.
3.Divide each mole value by the smallest number of moles calculated.
4.Round to the nearest whole number. This is the mole ratio of the elements and is.
Answer:
HBr + H2O = H3O+ + Br-
So our conjugate acid is the H3O+ to H2O
Explanation:
A conjugate acid of a base results when the base accepts a proton.
Consider ammonia reacting with water to form an equilibrium with ammonium ions and hydroxide ions:
NH3 (aq) + H2O (l) ⇌ NH4+ (aq) + OH- (aq)
Ammonium, NH4+, acts as a conjugate acid to ammonia, NH3.
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.
