Answer:
Coefficient in front of the 
in the balanced equation - 4
Explanation:
The unbalanced reaction is shown below as:-
On the left hand side,
There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side, 
must be multiplied by 6 and by 4
Left side, 
is multiplied by 5 and 
by 4 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the in the balanced equation - 4</u>
Answer:
The oxygen atom holds the electrons in a covalent bond more closely than the hydrogen atoms and develops a partial negative charge.
Explanation:
Water molecule is composed two hydrogen atoms and one oxygen atom.Both the hydrogen atom interact with the single oxygen by the formation of covalent bond.
Although the covalent bond is formed but the bonding electrons are not shared equally by both the atom.As oxygen is more electronegative than that of hydrogen atom,oxygen attract the bonding electron pair towards itself.
As a result the hydrogen atom get partial positive charge and oxygen atom gains partial negative charge.
Good luck my guy your going to need it
Answer:
Explanation: Avogadro number,N, = 6.02214076*10^23per mole —> 22.71L
—>( 7.41*10^26/N)*22.71 = 22.79*10^3 = 22,790L
