Metalloids:alloys of metallods are commonly used in discs like compact discs, CDs ,and DVDs .These materials change from glassy to crystalline with the application of heat which makes them useful as data storage media
As you go down deeper, less water is able to receive the heat from the sun or other sources, so naturally they would be cooler than the water at the top
Answer:
0.2042 M is the original concentration of
(aq) in the titrating solution.
Explanation:
Mass of
= 0.217 g
Moles of 
1 mole of
have 2 mole of As and 1 mole of
have 1 mole of As.
So, from 1 mole of
we will have 2 moles of 
Then from 0.001096 mol of
:
of 

According to reaction, 1 mole of
reacts with 2 mole of cerium (IV) ions,then 0.002192 mol of
of cerium (IV) ions.
Volume of the acidic cerium{IV) sulfate = 21.47 ml =0.02147 L
1 mL = 0.001 L

![[Ce^{4+}]=\frac{0.004384 mol}{0.02147 L}=0.2042 M](https://tex.z-dn.net/?f=%5BCe%5E%7B4%2B%7D%5D%3D%5Cfrac%7B0.004384%20mol%7D%7B0.02147%20L%7D%3D0.2042%20M)
0.2042 M is the original concentration of
(aq) in the titrating solution.
The answer to the problem is
69.55
Answer:
Oxygen
Explanation:
Oxygen has 6 valence electrons and it wants to have 8 to obtain a stable octet. So Oxygen gains two electrons in the bond, developing an anion.
It is also a non-metal, and they tend to gain anions.
