Answer:
The concentration of the murexide solution is 0.0000745 M
Explanation:
From Beer-Lambert's law,
A = εlc
A = Absorbance = 28.65% = 0.2865
ε = molar absorptivity = 3847 M/cm
l = path length = 1cm
c = concentration in mol/L = ?
c = A/εl = 0.2865/(3847×1) = 0.0000745 mol/L
Hope this Helps!
Carbon dioxide it should be water oxygen
Answer:
See explanation below
Explanation:
In this case, we have the equilibrium reaction which is:
H₂ + I₂ <------> 2HI Kp = 54
Now, we have the partial pressures of each element in equilibrium, therefore, we can use the expression of equilibrium in this case to calculate the remaining pressure:
Kp = PpHI² / PpH₂ * PpI₂
Solving for the partial pressure of iodine:
PpI₂ = PpHI² / PpH₂ * Kp
Replacing the given values, we have:
PpI₂ = (2.1)² / 0.933 * 54
PpI₂ = 4.41 / 50.382
PpI₂ = 0.088 atm
Answer:
The noble gases with complete outermost shell electrons.
Explanation:
Noble gases or inert gases do not react chemically with other elements because they have a complete configuration of their electronic shells. What drives chemical reaction is simply the exchange of electrons between two or more atoms. It can be a loss, a gain or simple sharing of electrons in order to achieve a complete configuration just like those of noble gases.
It is called the scientific method
