Answer: 23 liter
Explanation: Im pretty sure
When temperature increases, there is more energy in a substance. For example, when water boils, more energy is produced. The arrangement of molecules in a solid are closer together and more packed, while the arrangement of molecules in a liquid are father apart and less packed.
You need to check the weather to make sure its safe to hang glide, think about it you wouldn't want to go out and hang glide during a storm and if its not bad weather when you start, it could change depending on the forecast. So its good to always check and make sure there are no surprises when you are up in the sky.<span />
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.
