Answer:
100 celsuis
Explanation:
because it melts faster at a 100 degrees Celsius.
Answer:
D
Explanation:
1.) First convert to molar mass
18.1*1/231.533*18.01528=
I got 9.25527 for the pKa
<span>then for the Henderson-Hasselbalch equation: </span>
<span>9.00=9.25527+log(.600/acid) </span>
10^(-.25527)=(.600/acid)correct to this line. Then
0.5556 = 0.6/acid and
acid = 0.6/0.5556 = 1.08 which is the reciprocal of your number)
<span>.5556/.600M=acid </span>
<span>acid=.925925...M </span>
<span>(.925925)*2.10L= Molarity</span>
Answer:
The addition of sulfate ions shifts equilibrium to the left.
Explanation:
Hello!
In this case, according to the following ionization of strontium sulfate:
![SrSO_3(s)\rightleftharpoons Sr^{2+}+SO_4^{2-}](https://tex.z-dn.net/?f=SrSO_3%28s%29%5Crightleftharpoons%20Sr%5E%7B2%2B%7D%2BSO_4%5E%7B2-%7D)
It is evidenced that when sodium sulfate is added, sulfate,
is actually added in to the solution, which causes the equilibrium to shift leftwards according to the Le Ch athelier's principle. Thus, the answer in this case would be:
The addition of sulfate ions shifts equilibrium to the left.
