Answer:
50 mL; 7
Explanation:
By looking at the graph, the boundary point where the solution turns from acidic to basic appears at approximately 50 mL.
Because this is a titration between a strong acid and strong base, the pH of the equivalence point is always 7 (aka neutral).
"18) the element with the most stable nucleus and smallest mass per particle is:A) uranium.B)argon C) helium."
Answer:
The three methods we can use to separate a mixture are:
1.sublimation
example: sand and camphor
2.centrifugation
example:cream from milk
3.evaporation
example:salt from sea water
Answer:
Explanation:
Hello,
In this case, given the balanced reaction:
We can see a 2:4 mole ration between permanganate ion (118.9 g/mol) and manganese (IV) oxide (86.9 g/mol), that is why the resulting mas of this last one turns out:
Best regards.
