<h2>Answer:</h2>

<em>Hello, </em>

<h3><u>QUESTION)</u></h3>

Whatever the chemical entity, one mole of an entity contains 6.02 x 10²³ entities, this is the Avogadro constant (Na).  

<em>N = 2 x Na</em>

  • N = 2 x 6.02 x 10²³
  • N = 1.204 x 10²⁴

There are therefore 1.204 x 10²⁴ molecules of water in 2 moles of water.

The chemical equation is unbalanced and synthesized.

<h3></h3><h3>What is a chemical equation?</h3>

A chemical equation is described as the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.

In a chemical equation, the reactant entities are given on the left-hand side and the product entities is shown on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that indicates towards the products to show the direction of the reaction.

We can conclude that in the chemical equation shown is unbalanced because both amounts of the individual elements and compounds do not reflect on the reactant and product side.

The complete question is below:

After learning about the law of conservation of mass, Sammy became interested in balancing equations. He knew that the symbol for aluminum was Al and silver tarnish was Ag2S. He also knew that mixing the two chemicals yielded pure silver, or Ag, in an aluminum sulfide solution. Here is the equation showing this reaction:

3 Ag2S + 2 Al → 6 Ag + Al2S3

This equation is (synthesis / unbalanced / replacement / balanced), and it represents a(n) (unbalanced / balanced / synthesized / replaced) chemical reaction.

answer choices:

  • synthesis; balanced

  • balanced; replacement

  • unbalanced; synthesized

  • balanced; balanced
