The best describes on why and how Maggie should change her question to make it a better scientific question is that t<span>he question involves giving an opinion about recycling, so it should be changed to rely only on facts. Hope it helps! </span>
Answer : There are mainly three isotopes of magnesium found in nature; namely Mg-24, Mg-25 and Mg-26. Out of which Mg-24 has 12 neutrons, Mg-25 has 13 neutrons and Mg-26 has 14 neutrons in their atoms. The number of protons and their atomic masses remains the same for the atom. The relative abundance in nature differs for all the three isotopes. Mg-24 has abundance nearly 80% in nature, Mg-25 has abundance as 10% and Mg-26 has 11.01% abundance.
Based on the electronic configuration the elements are classified as metals, non metals and metalloids.
<u>Explanation:</u>
Periodic table consists of three major parts.
The left side consists of metals and the right side consists of non-metals and here Hydrogen element is the exception and in between those two regions we have metalloids, which has the dual character of both metals and non metals.
These elements can be grouped by means of its chemical properties and also due to its outermost electronic configuration.
If the valence shell electrons are same they are categorized under same group.
The vapor flowrate will vary with time by ; gradually increasing from zero to one half of the molar feed flow rate and then remain constant ( C )
<u>Although the options related to your question is missing attached below are the missing options </u>
<u />
Vapor flow rate is the amount of vapor per unit of time that flows through a specific area at a given time .
Given that the stream consists of 48.9 mole% of benzene and 51.1% toluene fed at a constant rate into a process unit. The vapor flowrate will vary with time because it will gradually increase from zero to 1/2 of the molar feed flow rate before it will remain constant.
Hence we can conclude that The vapor flowrate will vary with time by gradually increasing from zero to one half of the molar feed flow rate and then remain constant.
