The answer is C. There needs to be equal numbers of protons and electrons. If there are more or less electrons then the atom is no longer neutral!
The number of electrons will equal the number of protons In a neutral atom and the number of protons is the atomic number.
It is because water is a liquid form.
Add the reltive atomic mass of Ca and O which are 40 and 16 respectively after addition we get molecular mass of CaO which is 40+16=56 now divide atomic mass of O by molecular mass of CaO and multiply it with 100 as show n 16/56 *100=28.57%
Carbon-Oxygen
We breathe in oxygen, we breathe out carbon dioxide.
