Chemistry ! : neon has an average atomic mass of 20.2 g/mol, whereas argon has an average atomic mass of 40.0 g/mol. how would the number of atoms in a 1.0 mol sample of neon compare to the number of atoms in a 4.0 mol sample of argon? (2 points) a. the argon sample would have the same number of atoms as the neon sample. b. the argon sample would have twice as many atoms as the neon sample. c. the argon sample would have four times as many atoms as the neon sample. d. the argon sample would have eight times as many atoms as the neon sample.

C. The argon sample would have four times as many atoms as the neon sample.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

1 mole of neon contains= atoms

1 mole of argon contains=  atoms

Thus 4 moles of argon contains=  atoms

Thus the argon sample would have four times as many atoms as the neon sample.

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.
