In a science lab, when an acid is splashed on your skin what do you wash it with?

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?

If an atom has 12 protons and 13 neutrons

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.
