The correct response I believe is D. The reaction rate increases because the probability of collisions increases as there are more Zn atoms to react.
I think it’s c cause height is what determines gravitational potential energy
It's not, if it were it would be ice. The water is a bit warmer.
Answer: The Answer is C.
Explanation: The Nucleus only makes up less than .01% of the volume of the Atom. The Nucleus does contain more than 99.9% of the mass of the Atom. I hope that this helps you! Good luck!
<span>Correct answer is : 72.0 g/mole
If we assume Ideal Gas Law, PV = nRT. n = PV/RT = ((0.988 atm)*(0.258 L))/((0.0821 L*atm/mole*K)*(100 + 273.15)) = 0.00832 moles
Molar mass = 0.599 g/0.00832 moles = 72.0 g/mole; your answer is E.</span>
