If a compound is made of Sodium, Oxygen and Hydrogen is it 2NaOH, H2SO4, or 3CO2

1 answer

The compound that is made of sodium (Na), oxygen (O), and hydrogen (H) is NaOH, which is sodium hydroxide.

Here’s a breakdown of the compounds you mentioned:

  1. 2NaOH - This indicates two moles of sodium hydroxide, which is still comprised of sodium, oxygen, and hydrogen.
  2. H2SO4 - This is sulfuric acid, containing hydrogen (H), sulfur (S), and oxygen (O), but no sodium.
  3. 3CO2 - This is carbon dioxide, comprised of carbon (C) and oxygen (O), with no sodium or hydrogen.

So the only compound listed that contains sodium, oxygen, and hydrogen is NaOH (sodium hydroxide), regardless of the prefix.
