Answer:
The answer to your question is: 85.458 amu
Explanation:
data
Rubidium-85 A = 84.9118 amu abundance = 72.15%
Rubidium - 87 A = 86.9092 amu abundance = 27.85%
Atomic weight = ?
Atomic weight = 84.9118(0.7215) + 86.9092(0.2785)
Atomic weight = 61.2538 + 24.2042
Atomic weight = 85.458 amu
Answer:
it is ammonia nitro oxide
Answer:
b) Water boiling and mixing cola and root beer sodas are favorable processes, but assembling a house of cards is not.
Explanation:
Entropy, a measure of a system's thermal energy per unit of temperature that cannot be used to do work. Work, is obtained from directed motion of molecules, it follows the the amount of entropy is a measure of the molecular randomness, or disorder, of the system. As such increased entropy increases randomness hence water boiling and mixing cola and root beer sodas are favorable processes, but assembling a house of cards which requires a great deal of effort is not.
