Answer:
a. 6.57 cm
b. 8.17 cm
c. 0.80
Explanation:
a. The compound moved from where it was first placed, to a spot 7.57 cm from the bottom of the paper, in other words:
- 7.57 cm - 1.00 cm = 6.57 cm
b. A similar method is made for the solvent:
- 9.17 cm - 1.00 cm = 8.17 cm
c. The Rf of the factor is equal to the <u>distance that the compound moved divided by the distance the solvent moved</u>:
Neutrons released during a fission reaction trigger other fission reactions.
Answer:
0.0907 s
Explanation:
This an Arrhenius equation problem, so you relate the half-life with the kinetic constant of the reaction in order to calcule the same thermodynamic parameters at another temperature.
To calcule the kinetic constant of the reaction you need to know the order of it, look closely to the sentence "The value of the half-life is independent of the inital concentration of N2O present." the only order independent from the initial concentration of reagents is first order, so you can calculate K at 800 K, using:
Now you can use Arrhenius equation to calcule K at 1150.66 K
Then calculate the new half-life:
Answer:
the grams of H2O is 351g are processed form 9.75moles of H2
