Answer:
The equilibrium concentration of Butane = 1.17 molar and isobutane = 2.93 molar
Explanation:
Consider equilibrium constant for the isomerisation reaction of butane and isobutane at 25⁰C = 2.5
Answer:
measuring the mass of metal used in a reaction
B, because earths gravity if pulling on the moon and since velocity pulls it it’s like earth tied a string to the moon and the moon goes in a circle
Answer:
Different types of hot or cold items can be stored in a thermos and power cannot enter or exit the system when the thermos lid is tightly closed
Explanation:
Closed systems are those that do not interact or do not exchange energy with the environment that surrounds them, that is why internal temperatures and conditions are maintained.
The human body is an open system, that is, it would be the opposite of the thermos since we constantly exchange energy with the environment through sweating, emission of gases, urine, feces, and the ingestion of food.
Thermoses are systems specially created to maintain a medium, it will be maintained if its lid is hermetically closed to prevent heat leakage or entry in situations of cold fluids.
