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

Na2S + 2HCl > 2NaCl + H2S.

2NaCl > 2Na + Cl2

Na2S + 2HCl > 2NaCl + H2S

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.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
