For the answer to the question above, <span>17.9 x 1.74 gram Mg = 31.15 gram Mg = (31.15/24.31) = 1.28 mole Mg </span>
<span>2 Mg + O2 ---> 2MgO </span>
<span>so 1.28 mole Mg reacts with 0.641 mole O2
I hope my answer helped you. Feel free to ask more questions. Have a nice day!</span>
Answer:
6.214 degrees-mL/gdm
Explanation:
The specific rotation α' = α/LC where α = observed rotation, L = length of tube and C = concentration of solution.
Given that α = 1.74, L = length of cell = 50 mm = 0.50 dm and C = m/V where m = mass of glyceraldehyde = 5.60 g and V = volume = 10 ml
So, C = m/V = 5.60 g/10 ml = 0.560 g/ml
Since α' = α/LC
substituting the values of the variables into the equation, we have
α' = α/LC
α' = 1.74/(0.50 dm × 0.560 g/ml)
α' = 1.74/(0.28 gdm/l)
α' = 0.006214 °mL/gdm
α' = 6.214 °mL/gdm
α' = 6.214 degrees-mL/gdm

<u>Answer:</u> The value of 
for the equation is 
<u>Explanation:</u>
The given chemical reaction is:
The chemical equation for which the equilibrium constant is to be calculated follows:
As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.
The value of equilibrium constant for the equation is:
We are given:
Putting values in above equation, we get:
Hence, the value of for the equation is
