Assuming you mean "contain" in a physical sense (because chemically speaking, no element can "contain" a compound) ...
Sulfur should work. Carbon ought to work as well.
No, hydrochloric acid contains hyrogen and chlorine, so therefore it is not an element.
No- hydrochloric acid is an acid and is the opposite of an alkali so no alkalis contain it
The stomach contain hydrochloric acid.
No, hydrochloric acid (HCl) does not contain sulfur. It is a compound made up of hydrogen and chlorine atoms.
Most acids contain another element in addition to hydrogen, which is usually a nonmetal element such as oxygen, sulfur, or chlorine. This combination forms different types of acids, such as hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3).
Sanitary cleaner contain hydrochloric acid.
YES, IT WILL CONTAIN AN ACID LIKE HYDROCHLORIC [Hcl]
Compound
Non-oxyacids are a type of acid that do not contain oxygen in their chemical structure. They typically consist of hydrogen and another nonmetal element, such as hydrochloric acid (HCl) or hydrofluoric acid (HF). These acids are named using the prefix "hydro-" followed by the root of the nonmetal element and the suffix "-ic acid."
