1. Consider the reaction: 2Al + 6HBr ➔ 2AlBr3 + 3H2 a) If 194.0 g Al is mixed with 596.0 g HBr a reaction will occur. Determine the limiting reactant. b) How many grams of AlBr3 can be produced from this reaction? (Theoretical Yield)

c) How many grams of H2 can be produced from this reaction? (Theoretical Yield)

d) How many grams of the excess reactant will be left over after the reaction is complete?

e) If 6.73 g of H2 was actually produced and 601.4 g AlBr3 actually was produced, what is the percent yield of each product?

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
