Carbon, Helium, Oxygen ========================= Mine are Hydrogen (in water), Oxygen (in water and air), and Nitrogen (in air). Helium is not abundant on Earth at all.
What r the elements in potassium carbonate?
Because the chemical formula is K2CO3 the molecule contain potassium, carbon and oxygen.
Why can't potassium hydroxide be used to test for carbon dioxide?
it is because potassium hydroxide will react with carbon dioxide to form potassium carbonate and water. but potassium carbonate is soluble, so there will be no visible change to see if there is carbon dioxide emitted
Is potassium hydroxide contains potassium oxygen and helium?
NO!!! Potassium hydroxide contains;- 1 X potassium(K) 1 x Oxygen (O) 1 x Hydrogen (H). To give the formula 'KOH'. NB Helium is 'He'. It is the most unreactive element of all. It remains in the monatomic gaseous state. So it is not part of potassium hydroxide.
Who has the greatest atomic radius out of Helium Oxygen Carbon Nitrogen and Potassium?

Does helium have carbon dioxide in it?
Helium does not combine with other elements and pure helium will not have carbon dioxide in it.
Does helium produce carbon dioxide?
No. helium does not produce carbon dioxide
How does helium react with carbon monoxide?
helium has no chemical reaction with carbon dioxide
What 2 biochemical compounds support the idea things evolved from common ancestors?
Carbon and potassium
Is carbon dioxide lighter than helium?
