20.21*10^-4 mg/L is the concentration.
Explanation:
Given:
Pressure=1 atm.
Temperature= 0 degrees
Volume percent of air is 21%
Henry's Law constant K = 2.28 x 10^-3 mole/L-atm
The partial pressure of oxygen is 0.21 atm.
By Henry's law:
Concentration= K X Partial pressure
= 2.28*10^-3 *0.21
= 4.79*10^-4 moles/litre
Since, at STP 1 mole of oxygen occupies volume of 22.4L
concentration =mass/volume
mass = 4.79*10^-4-4*22.4
= 20.21*10^-4 mg
20.21*10^-4 mg/L is the concentration.
Angiosperms can produce flowers and fruits to aid in seed dispersal.
Answer:
The answer to your question is:
Explanation:
Compound Cation Anion Number of electrons
LiCl Li⁺¹ Cl⁻¹ one
NaF Na⁺¹ F⁻¹ one
CaO Ca⁺² O⁻² two
BaS Ba⁺² S⁻² two
NaBr Na⁺¹ Br⁻¹ one
6 protons would be Carbon, C
The better era tbh.......
