write the balanced equation because that the following chemical reactions.
(iii) sodium + Water → salt hydroxide + Hydrogen
price
(iii) salt + Water → sodium hydroxide + Hydrogen
The skeletal chemical equation that the above reaction is
Na + H 2 O → NaOH + H 2
name of the facet | No. Of atom in reactants | No. Of atom in Product |
sodium | 1 | 1 |
Hydrogen | 2 | 3 |
Oxygen | 1 | 1 |
You are watching: Sodium water balanced equation
number of atoms the Hydrogen in reaction ≠ number of atoms the Hydrogen in assets to balance variety of Hydrogen, we main point the NaOH in the product through 2 (If H2 is multiplied, the total number of H in the product will certainly be weird while that in the reactant is even. This will certainly make balancing difficult.) The chemistry equation becomes Na + H 2 O → 2 NaOH + H 2
surname of the element | No. Of atoms in reactants | No. Of atoms in Product |
salt | 1 | 2 |
Hydrogen | 2 | 4 |
Oxygen | 1 | 2 |
now , variety of atoms of sodium in reaction ≠ number of atoms of sodium in commodities come balance variety of Sodium, we main point the Na in the reaction by 2 The chemistry equation becomes 2 Na + H 2 O → 2 NaOH + H 2
surname of the facet | No. Of atom in reaction | No. Of atom in commodities |
salt | 2 | 2 |
Hydrogen | 2 | 4 |
Oxygen | 1 | 2 |
Now, number of atoms that Hydrogen in reactants ≠ variety of atoms that Hydrogen in products come balance Hydrogen and Oxygen, us multiply H 2 O in the reaction by 2 2 Na + 2 H 2 O → 2 NaOH + H 2
surname of the element | No. Of atom in reactants | No. Of atoms in assets |
salt | 2 | 2 |
Hydrogen | 4 | 4 |
Oxygen | 2 | 2 |
Now, every the elements are balanced and the well balanced equation is
2 Na + 2 H 2 O → 2 NaOH + H 2
2 Na + 2 H 2 O → 2 NaOH + H 2
