What is the theoretical yield of H2O that can be obtained from the reaction of 4.5 g H2 and excess O2? 2H2(g) + O2(g) --> 2H2O(g) A - 9.0 g B - 81 g C - 40 g D - 4.5 g E - 80 g Using the arithmetic problem below, determine the correct number of significant figures. (1.5 x 10 -4 x 61.3) + 2.01 = A - 2.0 B - 2.019 C - 2.0192 D - 2.019195 E - 2.02 Rutherford's experiment with alpha particle scattering by gold foil established that:

A) protons are not evenly distributed throughout an atom

B) protons are 1840 times heavier than electrons

C) electrons have a positive charge
