Answer: The answer is A. - 4.88x10^20 H2O2 molecules
Explanation: I hope this helps!
Elements in the same group tend to have very similar properties (D). This is due to the number of valence electrons each group has.
Answer:
KE = 1/2*m*v^2
KE = 1/2*150kg*(20 m/s)^2
KE = 75kg * 400m²/s²
KE = 30,000 kg*m²/s²
KE = 30,000 N*m
KE = 30,000 J
