(a)
Interpretation:
The given measurement is to be subtracted and the answer is rounded off to the proper significant digit.
Concept introduction:
During the addition or subtraction of measurements, the answer is found to be limited by the value with the greatest uncertainty that is the answer by the decimal place is limited. The final unit in addition and subtraction remains the same as the unit in each single data.

- Can you please help me and explain how I would find a mechanism consistent, using my results. Help with number 5.arrow_forwardThe conversion of (CH3)3CI to (CH3)2C=CH2 can occur by either a one-step or a two-step mechanism, as shown in Equations [1] and [2]. [1] + I + H₂Ö: :OH [2] q slow :OH + I¯ H₂Ö: a. What rate equation would be observed for the mechanism in Equation [1]? b. What rate equation would be observed for the mechanism in Equation [2]? c. What is the order of each rate equation (i.e., first, second, and so forth)? d. How can these rate equations be used to show which mechanism is the right one for this reaction? e. Assume Equation [1] represents an endothermic reaction and draw an energy diagram for the reaction. Label the axes, reactants, products, Ea, and AH°. Draw the structure for the transition state. f. Assume Equation [2] represents an endothermic reaction and that the product of the rate-determining step is higher in energy than the reactants or products. Draw an energy diagram for this two-step reaction. Label the axes, reactants and products for each step, and the Ea and AH° for each…arrow_forwardSteps and explanations.
