Question

chemist's found that a complex reaction occurred in three steps. the first step takes 2.5140 * 10^2s to complete, the second step takes 1.40 * 10^-1s, and and the third step takes 7.397 * 10^1s. what is the total amount of time elapsed during the reaction?​

Answer 1

The total amount of time elapsed during the reaction is 2.5227 × 10²s

Step-by-step explanation:

The total amount of time elapsed in this reaction would be to add the (three) individual time taken together: t = t₁ + t₂ + t₃

(2.514 × 10²s) + (1.4 × 10⁻¹s) + (7.397 × 10¹s) = 252.2797 ⇔ 2.5227 × 10²s
