To determine the correct list of elements in a chemical formula, we need to know the specific formula in question. However, from the options provided, we can analyze the elements:
- Carbon, hydrogen, cobalt, oxygen
- Carbon, hydrogen, oxygen
- Carbon, helium, oxygen
- Carbon, cobalt, oxygen
If you have the specific chemical formula, please share it, and I can help you identify which of the options correctly lists the elements contained in that formula. If you don’t have the formula available, I cannot definitively choose among the options given.
