Question

identify the number of atoms found in the chemicals below:
co2
carbon atom(s) and? oxygen atom(s)
h2o
? hydrogen atom(s) and? oxygen atom(s)

Explanation:

Step1: Analyze the formula \(H_2O\)

In \(H_2O\), the subscript \(2\) after \(H\) (hydrogen) means there are \(2\) hydrogen atoms. The subscript \(1\) (implied when no subscript is written) after \(O\) (oxygen) means there is \(1\) oxygen atom.

Step2: Analyze the formula \(CO_2\)

In \(CO_2\), the subscript \(1\) (implied) after \(C\) (carbon) means there is \(1\) carbon atom. The subscript \(2\) after \(O\) (oxygen) means there are \(2\) oxygen atoms.

Answer:

For \(H_2O\): \(2\) hydrogen atoms and \(1\) oxygen atom. For \(CO_2\): \(1\) carbon atom and \(2\) oxygen atoms.
