A. Strong Acid vs. Strong Base
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:
The question is a a bit confusing but since the melting point of copper is about 1000 Celsius we don't want to go that high so i think as long as we stay with 100 Celsius so all the water evaporates we are good
Answer:
Styrofoam could be heavier than a rock depending on how much weight you put on it,
Water is heavier than a ping pong ball,
A gold ring is not heavier than a pencil,
Oil is heavier than water because of the combined mass.
A large log is heavier than a small rock.
Explanation:
Answer:
A
Explanation:
First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. ... Molecular shape is also important, as the second group of compounds illustrate.
