1) Decomposition reactions. In this type of reaction, a compound is broken down into simpler compounds.
Option B is a decomposition reaction
B) ____ KClO3 → ____ KCl + ____ O2
The correct answer is A
its not D because a low pH is a acid
its not C because a base releases OH- ions
its not B because it donates and releases OH- ions
hope this helps
Answer:
One arrow is positioned in each box according to Hund's Rule which tells us to maximise the number of unpaired electrons in orbitals of the same subshell, and, to give those electrons the same "spin" (parallel spin).
Explanation:
Answer:
2KClO3 》》2KCl +3O2
C+ O2》》CO2
number of C moles
Required O2 moles (According to the mole ratio )
Relevant to the first equation, find the moles the KClO3, which is used to produce that amount of O2 moles
Now you can find the mass of KClO3
I mentioned the useful steps which can guide you to get the answer.
