(Claim - Evidence - Reasoning) why fluorine would rather bind to calcium than hydrogen as posed in the balance chemical equation above.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

< 3

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.

what is the question here. i think you messed up.
