A 45 kg skater in a 60 kg skater or standing still holding hands on frictionless ice do you push away from each other in opposite directions if the 45 kg skater was measured traveling at 3.5 M/S how fast was a 60 kg skater traveling

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

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!
