If you see this please me me rn for good karma How many atoms are there in 3.5 mols of NaCl (Sodium Chloride)? (1 mole
= 6.02 x 10^23)

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.

did anyone actually do this? like if anyone has submitted this i rly need .

i think it is true since you can test the answer and can use observations to complete it.
