Which of the following is a decomposition reaction?
a. 2so2 + o2 —> 2s03
b. zn + cu(no3)2 → zn(no3)2 + cu
c. 2h2o2–> 2h2o + o2
d . agno3 + nacl → agcl + nano3

The answer to your question is: letter C

Explanation:

Decomposition reaction is when one reactant gives two or more products.

a. 2SO2 + O2 —> 2S03                          This is a combination reaction

b. Zn + Cu(NO3)2 → Zn(NO3)2 + Cu      This is a single replacement reaction.

c. 2H2O2–> 2H2O + O2                         This is a decomposition reaction

d . AgNO3 + NaCl → AgCl + NaNO3      This is a double replacement reaction

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
