Assuming that the experiment started
with the magnesium and did not combine with oxygen, this extra mass would actually
decrease the amount of oxygen. This is because it only artificially increases
the original mass. Therefore this actually increases the error.
Answer:
<span>too low</span>
The number of atoms of fluorine that are present in the molecules of CF4 is calculated as follows
1 x4 = 4 atoms of fluorine
in CF4 they are four atoms of fluorine since the subscribe 4 indicate that they are four atoms of fluorine
Importance<span> of </span>Valence Electrons<span>. When two atoms approach each other and react with each other, it is their outer shells that come into contact first, and it is therefore the </span>electrons<span> in their outer shells that are normally involved in any chemical reaction.</span>
B. since Phosphorus has an atomic mass of 30.974 (larger) than Magnesium which is 24.305 (smaller)
Electrons: negative
Protons: positive
Neutrons: nuetral
