Answer: The word ‘Data’ means collection of information in the form of numerical figures, or a set of given facts. A data is a collection of numbers gathered to give some information.
Explanation: Visual representation of data will help us to understand it better and remember the facts easily. Hope this helped! :)
Answer:
molecularity of the rate-determining step
Explanation:
The rate determining step of a sequence of reactions is the slowest step in the sequence of non-elementary reactions.
The molecularity of the slowest step in the reaction mechanism gives us the rate law of reaction.
It is for this cause that the slowest step in the reaction sequence is called ''rate determining step'' since it determines the rate law of reaction.
Answer:
A. When a piece of copper is heated, it combines with oxygen to form copper oxide. The chemical reaction for the same is as follows:
2 Cu (s) + O2(g) => 2CuO
B. The mass of the piece of copper will remain same and there will be no change in its mass. However, its volume will increase, so its density will decrease.
C. This is so because heating copper in its elemental form is a physical change and there is no change in mass during a physical change. Hence, the mass of copper remain same.
They are exact copies of one another
There are two parent cells and two daughter cells
