Question

How many elements are in 2CO2?

Answer 1

The chemical formula \(2CO_2\) indicates that there are two molecules of carbon dioxide.

Each molecule of carbon dioxide (\(CO_2\)) consists of:
- 1 carbon (C) atom
- 2 oxygen (O) atoms

Since there are two \(CO_2\) molecules in \(2CO_2\), we can calculate the total number of each type of atom:
- Carbon atoms: \(2 \times 1 = 2\)
- Oxygen atoms: \(2 \times 2 = 4\)

Now, we can summarize:
- Total carbon atoms = 2
- Total oxygen atoms = 4

Thus, the total number of elements (or atoms) in \(2CO_2\) is:
\[2 + 4 = 6\]

So, there are a total of 6 atoms in \(2CO_2\).
