True...
that's where brownsted- lowry theory comes into consideration ,where the idea of conjugate base and acid pair comes in..
eg when water dissociates it serves as both the acid and base
H20[acid] + H20[base] -> H30+ [base] + 0H- [acid]
Ba(OH)2 Ba-2 power + 2 OH H2 + SO 4
All numbers are exponents.
The amount of sucrose in the sample would be 17 grams
<h3>Number of molecules of substances</h3>
There are 6.022 x
molecules in 1 mole of every substance.
3.0 x
molecules will, therefore, be:
1 x 3.0 x
/6.022 x
= 0.0498 moles
Mass of 0.0498 moles sucrose = 0.0498 x 342 = 17 grams

Answer:
when they have satisfied the octet rule naturally or through bonding to obtain full valence shells
Explanation:
Generally, most atoms of an element are unstable because they have a void in their electron shell to fill, hence, they need to react with other elements to fulfil this task of octet.
Octet rule states that atoms of elements engage in reactions to form compounds so they can have eight (8) valence electrons in their shell. Noble gases e.g argon, neon etc. are elements that have naturally satisfied this octet rule by possession of 8 valence electrons in their shell. Other elements that do not have this naturally becomes reactive and enter bonding with other atoms to obtain full valence shells.
Electronegativity is defined as the extent at which an atom can attract the bonding pair of another in a couvalent bond
fluorine has the highest electronegativity so away from it electonegativity decrease so the answer would be nitrogen as its the closes plus it has a strong nuclear charge with a small radius
