Question

In a Metathetical reaction, two species react to form two other species without oxidation or reduction.

For example: In an effort to form hydrogen (H₂) gas in my laboratory at room temperature, I’m using Zinc with hydrochloric acid at room temperature to form soluble zinc chloride and hydrogen.

Zn + HCl = ZnCl₂ + H₂

In the above equation, as zinc displaces hydrogen from HCl, this a displacement reaction. Here the resulting reaction shows that two molecules of HCl are required to supply two atoms of Cl and ZnCl₂ and two atoms of H for H₂. To demonstrate this, I created the following balanced equation.

Zn + 2HCl = ZnCl₂ + H₂

Discuss

Choose two species to react in a Metathetical reaction.

Provide the complete, properly balanced, chemical equations for such a reaction and a step by step description of how you balanced the equation.

please dont use other chegg answers, I have seen them.

Answer 1

The another displacement reaction with two species of sodium (Na) and Hydrogen chloride (HCl) reacts and produces sodium chloride (NaCl) and Hydrogen (H2).

Na + HCl = NaCl + H2

In the above equation, as sodium displaces hydrogen from HCl, this is a displacement reaction. Here the resulting reaction shows that two atoms of H are required to supply two atoms for H2. Therefore two atoms of HCl are required to supply two atoms of Cl in NaCl and two atoms of Na for two atoms of NaCl. To demonstrate this, I created the following balanced equation

2Na + 2HCl = 2NaCl + H2
