Answer:
Explanation:
The decomposition of follows the equation
By definition, the rate of a chemical reaction can be expressed by
The rate of appearance of is related to the rate of disappearance of by the stoichiometry. This means that, for each mole of that appears 2 moles of are consumed. So
Test Your Hypothesis by Doing an Experiment
Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test.
Option b I think :) hope this helped!
Answer:
The parts of an atom cannot be directly observed.
Explanation:
An atom is the smallest indivisible particle of a substance that can take part in a chemical reaction.
Atoms are not observed with naked eyes because they are found in the realm of very small particles. It is impossible to observe the parts of an atom directly.
As a result of this, models suffice in explaining the parts of an atom. Hence the answer.
