Question

Na2S + HCl NaCl + H2S NaCl Na + Cl2 Na2S + HCl NaCl + H2S balancing chemical equation

Answer 1

Balancing chemical equations like 2Na (s) + Cl2 (g) → 2NaCl (s) requires ensuring the same number of atoms for each element on both sides, considering diatomic molecules like Cl2.

Step-by-step explanation:

The subject of the question is the balancing of chemical equations in chemistry. When balancing chemical equations, it's crucial to remember that the number of atoms for each element must be the same on both sides of the equation. Let's consider the equation 2Na (s) + Cl₂ (g) → 2NaCl (s). This equation is balanced because there are two sodium (Na) atoms and two chlorine (Cl) atoms on both sides. This reflects the fact that chlorine exists as a diatomic molecule in nature, one of the seven elements that naturally occur as diatomic molecules: H₂, N₂, O₂, F₂, Cl₂, Br₂, and I₂.

Answer 2

Na2S + 2HCl -------------------> 2NaCl + H2S.

2NaCl --------------------------> 2Na + Cl2

Na2S + 2HCl ---------------> 2NaCl + H2S

Step-by-step explanation:

Stoichiometry Is one of important aspect of Chemistry that will be taught to student learning chemistry. It shows the relationship between the reactants and the product. For instance, the amount a reactant reacts to form the products and the amount of products formed.

The balanced chemical reaction for the equation of reaction given in the question is given below;

Na2S + 2HCl -------------------> 2NaCl + H2S.

One mole of Na2S reacts with 2 Moles of HCl to produce 2 moles of NaCl and one mole of H2S.

2NaCl --------------------------> 2Na + Cl2

Two moles of NaCl breaks down into 2 moles of Sodium(solid) and one mole of Chlorine.

Na2S + 2HCl ---------------> 2NaCl + H2S

One mole of N2S reacts with 2 moles of HCl to produce 2 moles of NaCl and one mole of H2S.
