A first-order reaction has a rate constant of 0.33minâ1. It takes min for the reactant concentration to decrease from 0.13 M to 0.088 M. A) 1.4B) 0.13C) 1.2D) 0.85E) 0.51

one state would change   like louisiana to texas. thats a change

explanation:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
