They are all part of one when something happens to one all layers experience the same changes.
The balanced chemical reaction is:
HC2H3O2<span> (aq) +Ba(OH)2 (aq) --> H2O (l) +Ba(C2H3O2)2
</span>
We are given the amount of HC2H3O2 to be used in the reaction. We use this amount as the starting point of our calculations.
0.432 mol HC2H3O2 ( 1 mol Ba(OH)2 / 1 mol HC2H3O2 ) = 0.432 mol Ba(OH)2 needed
Hope this answers the question.
Answer:
7.07585×10^24 molecules
Explanation:
# of Moles X Avogadro's Number= # of Molecules
<span>you'd get an explosion, but with radioactive materials which wouldn't be good...</span>
There are 2.16 moles of Lithium in 15 grams.
Look at the periodic table to find the molar mass of an element. Molar mass<span> of Lithium is 6.9410 g/mol.
Use dimensional analysis:
15g* (1mol/(</span>6.9410g/mol)<span>)=answer
The grams cancel out leaving you with your number in mol units.
Multiply it out and you get 2.16 moles of Lithium. </span>
