For the reaction: 2 H2 + 2 NO → N2 + 2 H2O the observed rate expression, under some conditions, is: rate = k[H2][NO]2 Which of the following mechanisms are consistent with these data? Select all that are True. step 1 H2 + 2 NO → N2O + H2O (slow) step 2 N2O + H2 → N2 + H2O (fast) step 1 2 H2 + 2 NO → N2 + H2O step 1 NO + NO ⇌ N2O2 (fast) step 2 N2O2 + H2 → N2 + H2O + O (slow) step 3 O + H2 → H2O (fast) step 1 H2 + NO ⇌ H2ON (fast) step 2 H2ON + NO → N2 + H2O2 (slow) step 3 H2O2→ H2O + O (fast) step 4 O + H2 → H2O (fast)

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.
