The overall chemical equation is upper c (s) plus upper h subscript 2 upper o (g) right arrow upper c upper o (g) plus upper h subscript 2 (g).. to calculate the final enthalpy of the overall chemical equation, which step must occur? reverse the first equation, and change the sign of the enthalpy. then, add. reverse the second equation, and change the sign of the enthalpy. then, add. multiply the first equation by three, and triple the enthalpy. then, add. divide the third equation by two, and double the enthalpy. then, add.

Respuesta :

Balancing the given equation we find that it will be equal to:

[tex]3NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+3H_2O+3CO_2[/tex]

What does balancing chemical equations mean?

Reaction balancing is a method used in several areas of Chemistry to determine the amount of matter of each of the substances participating in the reaction, as well as to establish the existing proportions between the components.

Then the equation before performing the balancing is given by:

[tex]NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+H_2O+3CO_2[/tex]

For this equation to become balanced it will be necessary that:

  • On the right side of the equation we have more Na and H so it will be necessary to multiply by 3

So the balanced equation will be:

[tex]3NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+3H_2O+3CO_2[/tex]
