(80+125+45) / 10 = 250/10 =25
25 meters per minute= 0.41 meters/second
the direction and stopping time is irrelevant to the problem.
Answer:
Explanation:
Hello there!
In this case, since the integrated rate law for a second-order reaction is:
Thus, we plug in the initial concentration, rate constant and elapsed time to obtain:
Best regards!
In a physical change, the substance just changes the state or physical form without affecting the chemical composition of the substance. Some examples of physical change are phase transitions (melting, evaporation), crushing a bottle, the process of dissolution and so on.
Among the given options, the physical form of the ball of clay changes only when the ball is broken into two separate halves and the ball of clay is flattened into a pan-cake like shape. There would be no change in physical form or state when the ball is thrown into the air or rolled along the ground.
So, the correct answer will be: d. II and IV only
