Answer:
Explanation:
Potential energy builds as the coaster is going up the loop-the-loop and converts to kinetic energy on the way down and out of the loop-the-loop. The potential energy of the coaster is at its lowest and the kinetic energy is at its highest as the coaster moves in the lowest point of the loop-the- loop.
Hey there!
AlCl₃ + NaOH → Al(OH)₃ + NaCl
Balance OH.
1 on the left, 3 on the right. Add a coefficient of 3 in front of NaOH.
AlCl₃ + 3NaOH → Al(OH)₃ + NaCl
Balance Cl.
3 on the left, 1 on the right. Add a coefficient of 3 in front of NaCl.
AlCl₃ + 3NaOH → Al(OH)₃ + 3NaCl
Balance Na.
3 on the left, 3 on the right. Already balanced.
Balance Al.
1 on the left, 1 on the right. Already balanced.
Our final balanced equation: AlCl₃ + 3NaOH → Al(OH)₃ + 3NaCl
Hope this helps!
<span>Radium and Polonium were named in honor of Marie Curie.
SO yeh true
Hope this helps!

Answer:
(B.) and (C.)
b. So that clean NMR spectra can be obtained that do not contain solvent peaks.
c. So that the yield can be determined.
Explanation:
The solvent used in Nuclear Magnetic Resonance (NMR) spectrometer is Trimethyl silane (TMS), a neutral solvent which doesn't give off any signals. Other solvents could have interactions with the radiation, and disrupt the spectra.
Furthermore, for accurate determination of the actual yield and overall percentage yield, solid must be separated from the solvent, dried and weighed.
I hope this was explanatory enough.
