draw it! what does the big 2 in 2co2 mean? what does the little 2 in 2co2 mean? goal: 2co2 draw it! what does the big 4 in 4h2 mean? what does the little 2 in 4h2 mean? goal: 4h2 4 molecular of h2 2 atoms of hydrogen

Explanation:

Step1: Analyze 2CO₂

The big '2' in 2CO₂ represents 2 molecules of carbon - dioxide. The little '2' in 2CO₂ represents that each carbon - dioxide molecule contains 2 oxygen atoms.

Step2: Analyze 4H₂

The big '4' in 4H₂ represents 4 molecules of hydrogen. The little '2' in 4H₂ represents that each hydrogen molecule contains 2 hydrogen atoms.

Answer:

• In 2CO₂, the big '2' means 2 molecules of carbon - dioxide; the little '2' means each CO₂ molecule has 2 oxygen atoms.
• In 4H₂, the big '4' means 4 molecules of hydrogen; the little '2' means each H₂ molecule has 2 hydrogen atoms.
