Answer:
Because in elastic collisions there is no heat emission or absorption.
Explanation:
A collision is considered elastic when the total kinetic energy of the study system is conserved during the collision. Since the total kinetic energy is conserved, heat is not emitted or absorbed during the collision. Since the emission or absorption of heat is what produces changes in temperature, If the system remains at a constant temperature, there were only elastic collisions.
Answer:
D
Explanation:
I hope this right, I'm sorry if it's not.
For an atom to be neutral, it has to have the same amount of protons and electrons. Because protons and electrons have opposite charges, when there is an equal amount of them they balance each other out
Explanation:
The given reaction equation will be as follows.
Let is assume that at equilibrium the concentrations of given species are as follows.
M
M
M
Now, first calculate the value of as follows.
=
=
Now, according to the concentration values at the re-established equilibrium the value for will be calculated as follows.
M
Thus, we can conclude that the concentration of in the new equilibrium mixture is M.
Answer:
The formula of acceleration is final velocity-initial velocity÷time taken
