Solution Steps

Step 1: Identify the molecule

The given molecule is ethyne (C₂H₂), also known as acetylene.

Step 2: Understand the Brønsted-Lowry concept

In the Brønsted-Lowry theory, an acid is a proton (H⁺) donor, and a base is a proton acceptor. The conjugate base of an acid is formed by removing a proton (H⁺) from the acid.

Step 3: Remove a proton from the molecule

To form the conjugate base of ethyne, remove one hydrogen atom (H⁺) from the molecule. This results in the formation of the acetylide ion (C₂H⁻).

Final Answer

The Brønsted-Lowry conjugate base of ethyne (C₂H₂) is the acetylide ion (C₂H⁻).

QUESTION 11 Use the following to answer questions 11 thru 14. Two blocks of masses m1=12.0 kg and m2=30.0 kg are connected by a light string as shown below. The coefficient of kinetic friction between m1 and the table is μ=0.250 and m2 is initially located at y=6.0 meters above the floor. Assuming the system starts from rest, draw a free body diagram for each block and determine the normal force acting upon m1.

Suppose the president is attempting to decide whether the federal government should spend more on research to find a cure for heart disease. What is the opportunity cost of spending more money to find a cure for heart disease? A. The reduction in funding for research to cure other diseases. B. The reduction in future health-related costs of heart disease. C. The cost of the Medicare/Medicaid program. D. The monetary value of a human life. E. The total explicit cost of the research to cure heart disease. How should policymakers determine the amount of money that should be allocated for research curing heart disease? They should base their decision on A. the value of the total benefit of research on curing other diseases. B. whether the last dollar devoted to research on heart disease results in more benefit than the last dollar spent on research for curing other diseases. C. the number of people who die from heart disease compared to the number of people who die from other diseases. D. the value of the total benefit of the research on heart disease. E. the number of people who have heart disease compared to the number of people who have other diseases.
