Respuesta :
In general start with the elements that appear once on each side, then fill in what’s left.
Na + O2 —> Na2O
Balance O’s:
Na + O2 —> 2Na2O
Balance Na’s:
4Na + O2 —> 2Na2O
Same idea for the others. Here’s the final solutions so you can check after you try them yourself:
C8H16 + 12O2 —> 8CO2 + 8H2O
4NH3 + 5O2 —> 4NO + 6H2O
Na + O2 —> Na2O
Balance O’s:
Na + O2 —> 2Na2O
Balance Na’s:
4Na + O2 —> 2Na2O
Same idea for the others. Here’s the final solutions so you can check after you try them yourself:
C8H16 + 12O2 —> 8CO2 + 8H2O
4NH3 + 5O2 —> 4NO + 6H2O
Answer :
(35) The balanced chemical reaction will be,
[tex]4Na+O_2\rightarrow 2Na_2O[/tex]
(36) The balanced chemical reaction will be,
[tex]C_8H_{16}+12O_2\rightarrow 8CO_2+8H_2O[/tex]
(37) The balanced chemical reaction will be,
[tex]4NH_3+5O_2\rightarrow 4NO+6H_2O[/tex]
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.
The coefficient tell us about that how many molecules or atoms present in the chemical equation.
Part 35 :
The unbalanced chemical reaction is,
[tex]Na+O_2\rightarrow Na_2O[/tex]
This reaction is an unbalanced chemical reaction because in this reaction number of sodium and oxygen atoms are not balanced.
In order to balance the chemical equation, the coefficient '2' put before the [tex]Na_2O[/tex] and the coefficient '4' put before the [tex]Na[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]4Na+O_2\rightarrow 2Na_2O[/tex]
Part 36 :
The unbalanced chemical reaction is,
[tex]C_8H_{16}+O_2\rightarrow CO_2+H_2O[/tex]
This reaction is an unbalanced chemical reaction because in this reaction number of carbon , hydrogen and oxygen atoms are not balanced.
In order to balance the chemical equation, the coefficient '12' put before the [tex]O_2[/tex], the coefficient '8' put before the [tex]CO_2[/tex] and the coefficient '8' put before the [tex]H_2O[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]C_8H_{16}+12O_2\rightarrow 8CO_2+8H_2O[/tex]
Part 37 :
The unbalanced chemical reaction is,
[tex]NH_3+O_2\rightarrow NO+H_2O[/tex]
This reaction is an unbalanced chemical reaction because in this reaction number of carbon , hydrogen and oxygen atoms are not balanced.
In order to balance the chemical equation, the coefficient '4' put before the [tex]NH_3[/tex], the coefficient '5' put before the [tex]O_2[/tex], the coefficient '4' put before the [tex]NO[/tex] and the coefficient '6' put before the [tex]H_2O[/tex] then we get the balanced chemical equation.
The balanced chemical reaction will be,
[tex]4NH_3+5O_2\rightarrow 4NO+6H_2O[/tex]
