Which equation is balanced?

Mg3N2 + H2O 3MgO + 2NH3
C3H8 + 5O2 H2O + 3CO2
Zn + 2HCl ZnCl2 + H2
3H2SO4 + 2Fe Fe2(SO4)3 + H2

Respuesta :

Answer:

it's the third one

Explanation:

in the first one oxygen molecules aren't balanced

the second ok me oxygen isnt balanced

and the fourth one hydrogen isn't balanced

hope it helps ;)

A balanced equation is a representation in which the coefficients of the individual atoms of a molecule or compound are the same on both the left and right of the equation.

The correct answer is:

Option C. Zn + 2 HCl -------->  ZnCl₂ + H₂

This can  be explained as:

  • In the first equation, the number of H and O atoms are not balanced.

  • In the second case, the atoms of hydrogen and oxygen are not the same on the sides of the equation.

  • In the third reaction between zinc and hydrochloric acid, all the atoms of the reaction are balanced.

  • In the fourth reaction, the hydrogen atoms are not balanced.

Therefore zinc and hydrochloric acid reaction are balanced.
