Answer 1

13) Incorrect is (A) Ba(NO3)2 + N22504 → Basot + - ZNANO3 A Imol C has=6.022 x 1023 atoms 6.25moles C has 6.022 x 1023x6.25 = 37.64 x 1023 atoms 15 3H₂ + N₂ 2NH3 3.689 ? 3 mol H₂ yields = z mol NH3 or 3 x 29 4₂ "=2x179 NU3 .9 H₂ " = 2x17 *3.68 3x2 = 20.859 NU3 given man Molar mass Moles = 20085 = [1.23 mol NU3 16) thi + O2 ~2lizo 0.1259 0.125g ?ģ
