Balance the following chemical equations:
A) N2 + H2 → NH3
B) Na + H2O → NaOH + H2
How will you say that these equations are balanced?
Answers
Answer:
a) The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.
b) Balanced equation: 2Na+2H2O→2NaOH+H2
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
Explanation:
balanced equations. a chemical equation in which there are equal numbers of each type of atom on each side of the equation. Synonyms and related words. Chemical reactions and processes.
hence these equations are balanced
