Is acs omega open access?

I'm curious to inquire about the accessibility of ACS Omega. Is it an open-access journal, meaning that readers can freely access the full content of its published articles without subscription or paywalls? This information is crucial for researchers and academics alike, as open-access journals enhance the dissemination of knowledge and foster collaboration across the scientific community. Could you please clarify whether ACS Omega adheres to this open-access model?
