For any two elements A and B that form AB, neither A nor B have to be invertible for (AB)-1 to exist, right?
See my counterexample.defunc said:Both have to be invertible. Inv(AB) = inv(B)inv(A).
When two elements, let's say A and B, combine to form a compound called AB, it means that the atoms of A and B have bonded together through a chemical reaction to create a new substance with different properties than the individual elements.
Yes, elements A and B can form more than one type of compound depending on the conditions under which they react. For example, hydrogen and oxygen can form water (H2O) or hydrogen peroxide (H2O2).
No, it is not necessary for both elements to be present in equal amounts for them to form a compound. The ratio of elements in a compound depends on the chemical formula of the compound. For example, in water (H2O), the ratio of hydrogen atoms to oxygen atoms is 2:1.
Yes, elements A and B can still form a compound even if they have similar properties. The properties of a compound are different from the properties of its individual elements. For example, sodium (Na) and chlorine (Cl) have very different properties, but when they combine to form sodium chloride (NaCl), the compound has its own unique set of properties.
No, a chemical reaction is necessary for elements A and B to form a compound. This means that the atoms of A and B must bond together in a new arrangement to create a new substance with different properties. If no chemical reaction occurs, the elements will remain in their original form.
