the kelp has the most available energy.
Releasing the string would most likely increase the kinetic energy, as kinetic energy is energy in motion. However, if you were to increase the potential energy, then the string would have to be pulled back more, as potential energy is stored energy within an object.

Answer:
77%
1.98/2.57= 0.770428016 = 77%
MnO2 + 4HCl = MnCl2 + Cl2 + 2H2O
m(HCl) = 36.45/48.2 = 0.76
every 4 moles of HCl will only react with 1 mole MnO2 and there is less HCl therefore HCl will be used up first.
Excess MnO2 = 0.86 - (0.76/4) = 0.67m
grams MnO2 = 0.67x 86.93= 58.24grams left over.
Every 4 moles HCl will only form 1 mole Cl2 so m(Cl2)=0.76/4=0.19
0.19x70.9=13.47grams Chlorine formed
