Question

1. sep develop models the chemical equation below is written with molecular models in place of chemical formulas. on the left is a carbon (c) atom and a molecule of oxygen. on the right is a molecule of carbon dioxide. translate the visual model into a chemical equation.

Explanation:

Step1: Identify chemical formulas

The black sphere represents \(C\) (carbon atom), the red - red sphere represents \(O_2\) (oxygen molecule), and the red - black - red sphere represents \(CO_2\) (carbon dioxide molecule).

Step2: Write the chemical equation

Based on the visual model, the reactants are \(C\) and \(O_2\), and the product is \(CO_2\). The chemical equation is \(C+O_2
ightarrow CO_2\). But we need to balance it.

Step3: Balance the chemical equation

Count the number of atoms on both sides. For oxygen, there are 2 atoms on the left (\(O_2\)) and 2 atoms on the right (\(CO_2\)). For carbon, there is 1 atom on the left (\(C\)) and 1 atom on the right (\(CO_2\)). So the balanced chemical equation is \(C + O_2=CO_2\)

Answer:

\(C + O_2=CO_2\)
