Answer:
Explanation:
The average atomic mass for any element will be closest to the average atomic mass of the __different______ isotopes.
To calculate the average atomic mass of any element, the mass spectrometry method helps to determine the proportion/percentage/fraction by which each of the isotopes of an element occurs in nature. The proportion is called the geonormal abundance or abundance. From this, the average atomic mass of an element from different isotopes can be calculated.
Answer: Please see explanation column for answer.
Explanation: For A two-component mixture containing 1-octene and 1, 4-dimethylbenzene with acetone.
Error----- The retention factor (Rf) is 0.95 and the two spots are coming simultaneously together producing only one spot indicating that that the choice of solvent we have used is too polar. The compounds are interacting rapidly with the very polar solvent and have very low interaction with the stationary phase. than the mobile phase.
Solution:-----, We will need to try other low polar solvent that can allow two spots to be formed on the TLC plate eg is the use of different percentage s of hexane in ethyl acetate ether 10% or 20%.
Answer:
The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust. High tides are when water bulges upward, and low tides are when water drops down.
