This vatue is NOT used in calculations below Write the balanced equation of magnesium and HCl to form hydrogen gas and magnesium salt (2 pts) Prior to placing the eudiometer into the Equalization Chamber, is the pressure of the gas inside the tube greater than or less than the pressure outside the tube? Comparing the volume of the gas before and after placing the eudiometer into the Equalization Chamber should help with the explanation. Explain your logic. (4pts) : What experimental measurement most affected the accuracy of the experimental value of R ? Explain. (HINT: Consider the significant figures in your data.) (3 pts.) What experimental changes might improve the accuracy of the determined R value? ( 3 pts.)
