To know which is a better solvent between the two, one should know what will be the solute. It really depends on what type of solute you have. If the solute is polar then water is the better solvent for that type of solute. However, when the solute is a nonpolar substance then carbon tetrachloride is the better solvent.
1) period
2) the answer is D) I because they are in the same column
3) B)Ge because they are in the same column
4) A) Al because they are in the same column (share same characteristics)
5) D) they have the same number of valence electrons
6) D) nonmetals
Answer and Explanation:
- <em>Computers ( The computers are very old and very slow, and we have to notice that almost everyone are using computers at the same time at the school, which makes it even harder for it to load up assignments. )</em>
- <em>The Rick Rolling ( Everyone keeps sending links to teachers and students saying that it is part of some assignment but then you have to listen to Rick Astley, they should really block these links. )</em>
- <em>The lockers ( The lockers are also very old and they are breaking down and rusting a lot from the moisture in the hallways. One of the lockers even broke down today!!! I hope they can fix this so no one else gets hit with a locker door. )</em>
<em>Hope this helps! ;)</em>
Answer:
Oxygen and Carbon are in the non-metal section. Both are in 2nd period while Carbon is in group 4A and Oxygen is in group 6A.
Oxygen has more valence electrons than carbon. I wish I could give you a more accurate explanation why on paper, but all you need to do is count the electrons on the largest shell.
Here's the orbital notation of Carbon: 1s^2 2s^2 2px^1 py^1
Carbon's largest shell is 2. Count the electrons on shell 2, and you get 4 valence electrons.
Orbital notation of Oxygen: 1s^2 2s^2 2px^2 py^1 pz^1
Oxygen's largest shell is 2. So, like with carbon, count the electrons on the largest shell. You get 6.
There is a way easier way of interpreting this where you do not even have to write the orbital notation. I wish I can explain, but just know the periods and the group numbers.
