Answer:
mg atom have 12 election and mg ion have 10 election
Answer:
Kp = 41.53
Kc = 1.01
Explanation:
To calculate the equilibrium constant in terms of pressure, what we simply do is to use the equilibrium pressure raised to the power of the number of moles. What we are saying in essence is this:
Kp = [NOCl]^2/[NO]^2[Cl]
Kp= [0.25]^2/[0.174][0.093]^2 = 41.53
Kp = Kc (RT)^Dn
Hence, Kc = Kp/[RT]^(delta n )^-1
n = sum of the number of moles of products minus the sum of the number of moles of reactants= 2-3 = -1 in this case
Kc = 41.53/(0.0821 * 500)^1
Kc = 1.01
Answer:
Digital scales /weight scales (the stuff you weigh yourself to see how much lbs you are)
Explanation:
Answer:
f = 1.1041 × 10¹⁵ s⁻¹
λ = 2.72 × 10⁻⁷ m
Explanation:
Given data:
Energy of photon = 7.32 × 10⁻¹⁹ J
Wavelength = ?
Frequency = ?
Solution:
Formula
E = h. f
h = planck's constant = 6.63 × 10⁻³⁴ Kg.m²/s
Now we will put the values in equation
f = E/h
Kg.m²/s² = j
f = 7.32 × 10⁻¹⁹ Kg.m²/s² / 6.63 × 10⁻³⁴ Kg.m²/s
f = 1.1041 × 10¹⁵ s⁻¹
Wavelength of photon.
E = h.c /λ
λ = h. c / E
λ = (6.63 × 10⁻³⁴ Kg.m²/s × 3 × 10⁸ m/s) / 7.32 × 10⁻¹⁹ Kg.m²/s²
λ = 19.89 × 10⁻²⁶ / 7.32 × 10⁻¹⁹ m
λ = 2.72 × 10⁻⁷ m
Answer:
the number of atoms stays the same as the atoms lose energy to the colder freezer, slow down, get closer together, shrinking the volume
Explanation:
When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid.
