Answer:
Explanation:
2 moles hydrogen reacts with one mole of oxygen to give 2 moles of water.
a ) rate of consumption of hydrogen ( moles per second) is twice the rate of consumption of oxygen .
b ) rate of formation of water ( moles per second ) is twice the rate of consumption of oxygen
c ) rate of formation of water ( moles per second ) is equal to the rate of consumption of hydrogen.
The option that distinguishes a nuclear reaction from a chemical reaction is D. there is a change in the nucleus.
During a nuclear reaction, two light nuclei combine in order to create a new, heavier one which is different than those two original ones and has additional particles that it didn't have originally. This is what makes the difference between these two reactions.
The momentum of the body is 12 m/s.
<h3>What is momentum?</h3>
Momentum is the product of the mass of a body and velocity. According to Newton's second law, the rate of change of momentum is equal to the impressed force.
The details required to answer the first two questions are missing hence we can't answer those questions. For the last question;
p = mv
m = mass
v = velocity
p = momentum
v = p/m
v = 72,000 kgm/s/6,000 kg
v = 12 m/s

Answer:Kinetic energy = (1/2)*mass*velocity^2
KE = (1/2)mv^2
KE = (1/2)(478)(15)^2
KE = 53775J
Explanation:
Kinetic energy = (1/2)*mass*velocity^2
KE = (1/2)mv^2
KE = (1/2)(478)(15)^2
KE = 53775J
