Why do you think scientists claim to offer only supporting evidence for a theory and not proof?

This chart lists four kinds of polymers and their sources. what can be known about all four polymers, despite their differences? they come from living things. they share ionic carbon bonds. they are at least 100 monomers long. they are made of repeating subunits.

What changes occur in the reaction indicated by the equation? check all that apply. the hydrogen nucleus loses protons. the oxygen nucleus gains protons. the bond in h2 is broken, and new bonds are formed between hydrogen and oxygen atoms. each electron associated with a hydrogen atom is shared with an oxygen atom.

It takes 155. kj/mol to break a fluorine-fluorine single bond. calculate the maximum wavelength of light for which a flouine-flouring single bond could be broken by absorbing a single photon
