Answer:
Kp = 8.76×10⁻³
Explanation:
We determine the carbamate decomposition in equilibrium:
NH₄CO₂NH₂ (s) ⇄ 2NH₃(g) + CO₂(g)
Let's build the expression for Kp
Kp = (Partial pressure NH₃)² . Partial pressure CO₂
We do not consider, the carbamate because it is solid and we only need the partial pressure from gases
Kp = (0.370atm)² . 0.0640 atm
Kp = 8.76×10⁻³
Remember Kp does not carry units
EThe answer is Evaporation
Answer:
λ = 1.62×10¹¹ nm
Explanation:
Wavelength of radiation = ?
Frequency of radiation = 1.85 MHz (1.85 ×10⁶ Hz)
Solution:
Formula:
Speed of radiation = frequency × wavelength
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 1.85 ×10⁶ Hz × λ
λ = 3×10⁸ m/s / 1.85 ×10⁶ s⁻¹
λ = 1.62×10² m
In nm:
1 m = 10⁺⁹ nm
λ = 1.62×10¹¹ nm
<span>A solution is somthing desolved in somthing else. By desolved i mean it needs to have some particals ionized a solid you place in water that dissosiates (ions split apart from each other) makes a solution a good solution you can make in your kitchen is a salt-water solution, Put some regular table salt in a glass and stir it and you will notice the salt "disapears" what happens is the sodium ions and the chloride Ions seperate and 'hide' between water molocules.
In basic terms only some substances can make a solutions others are refered to as insoluble as they can't be seperated in water or another solvent. In actuality however all ionic compounds (compounds that are composed of ions) are at least somewhat soluble, but don't dissociate well at all in some solvents.
Hope that helps</span>
Noon, the sun would have the greatest effect on the water during evaporation
