It is a universal constant used for all gases
Oil and water can separate by utilizing a separating funnel, oil and water are totally insoluble in one another. The water structures lower while the oil forms the upper layer.
The liquids hexane
and water are placed in a test tube. The test tube is stoppered, shaken, and
placed in a test tube rack. The liquids separate into two distinct
layers because hexane and water have different molecular polarities. The answer
is number 2.
<span>To compute 4.659×104−2.14×104, the first step is the factorization. That is as follows:4.659×104−2.14×104= 10^4.(4.659−2.14), the next step is to compute 4.659−2.14=2.51, so 10^4.(4.659−2.14)=2.51x10^4=2.51x 10000 (because10^4=10000), the last calculus is 2.51x 10000=25100, the final answer is 25,000.Hope this helps.
