c) no reaction will occur
d) zinc nitrate will form

27.7 grams of Li

0.140 moles of Co

0.158 moles of K

59.9 grams of As

8.00x10⁻⁹ moles of U

142.8 moles of H

0.0199 moles of O

0.666 moles of Pb

Explanation:

Mass / Molar mass = Mol

Mol . Molar mass = Mass

3.99 m . 6.94 g/m = 27.7 grams of Li

8.28 g / 58.93 g/m = 0.140 moles of Co

6.17 g / 39.1 g/m = 0.158 moles of K

0.8 mol . 74.92 g/m = 59.9 grams of As

6.02x10²³ (NA) particles are contained in 1 mol

6.02x10²³ are contained in 1 mol U 1 mol  H 1 mol O ___ 1 mol Pb

4.82x10¹⁵ atoms U   4.82x10¹⁵/ 6.02x10²³ = 8.00x10⁻⁹ moles of U

8.60x10²⁵atoms H   8.60x10²⁵ / 6.02x10²³  = 142.8 moles of H

1.20x10²² atoms O   1.20x10²² / 6.02x10²³ = 0.0199 moles of O

4.01x10²³ atoms Pb 4.01x10²³ / 6.02x10²³ = 0.666 moles of Pb
