The empirical formula or simplest formula
gives the smallest whole-number ratio of
the atoms present in a compound.It gives the
relative number of atoms of each
element present in the compound.The ratio will be 3.72 : 21.28
Your protons are correct but it’s 28 neutrons not 27!
You can change any variable in an experiment (the amount of water, sun, type of light, fertilizer etc.) but for the experiment to be VALID only one thing can be changed for the experiment.
Example: I’m trying to see if the plant will grow better with more or less water so the only thing that changes is the amount of water. Everything else will have to be the same (type of plant, fertilizer,dirt, container it grows in, amount of light etc.)

Explanation:
because it is products /reactants :)
0.986 moles of CaO are formed when 98.60 g of decomposes.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others.
Number of moles of CaCO3 =
Number of moles of CaCO3 =
= 0.986 moles
Reaction:
→
Since the reaction is 1:1:1.
So 0.986 moles of CaO are formed.
