Answer:
for the balanced equation
Answer: Carbon nanotubes, especially multi walled carbon nanotubes, are so strong because they are a single chain of unbroken covalent carbon-carbon bonds.
Explanation:
Answer:
Sorry; I am unfamiliar with the details they taught you. I would guess #3, for it allows kinetics to “work on the particles”. #1 makes no sense; what is
“Large”? #2 infers all particles are charged....#4. Seems unclear to me.
Maybe these thoughts will jar your memory.

Answer:
196J, but C. at 200 J comes close.
Explanation:
Potential energy due to gravity is given by:
PEgrav = mass • g • height
where g is the acceleration due to gravity. We'll use 9.8 N/kg (on Earth).
PEgrav = mass • g • height
PEgrav = (2 kg) • (9.8 N/kg) • (10 m)
PEgrav = 196 N*m
1 N*m = 1 Joule
PEgrav = 196 J
C. at 200 J comes close. The solution probably used a value of g equal to 10 N/kg)
