Answer:
The sum of each elementary step in a reaction mechanism must yield the overall reaction equation. The rate law of the rate determining step must agree with the experimentally determined law.

A chemical is said to be stable if it is difficult to get it to react. This property of a chemical is a <u>physical</u> property
Answer: speed and velocity, but no acceleration
Explanation:
Velocity and acceleration are both vector quantities, and as vectors they have magnitude and direction. So, if one of this elements (or both) changes, this quantities also changes.
In the case of velocity, its magnitude is the speed and its direction is to the East.
In the case of acceleration, which is the variation of velocity in time, since is constabt and the direction is the same, the acceleration is zero.
Therefore:
<h3>
An object that is traveling east at a constant rate has <u>
speed and velocity, but no acceleration.</u></h3>
Answer:
150km/hr
Explanation:
When it flies 50km, the average speed is 150km/hr.
When it flies 30 km, how many minutes does it take?
