Substances have more kinetic energy in the gas state than in the solid state
Answer:
Pancreas.
Explanation:
Living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Pancreas is one of the glands of the endocrine and digestive systems that produces insulin to help control the body's sugar levels and enzymes which aid in digestion.
Answer:
The percent yield for ethanol in this process is 95.2%
Explanation:
Yield is the ratio between the amount of product actually obtained in the reaction and the maximum amount of product that could have been obtained if the reagents had been completely consumed.
The theoretical yield is the yield is the maximum you can get in a reaction.
On the other hand, the actual performance shows what you really get in experimentation. It is generally less than the theoretical yield.
So, the percentage return is the actual return times the theoretical return multiplied by 100.
So, in this case the percentage yield will be calculated as:
percent yield= 95.2%
<u><em>The percent yield for ethanol in this process is 95.2%</em></u>
True!
Because if it has a high pressure, it can skip the liquid phase. The process is called sublimation.
