The ratio of C 14 / C 12 is a constant. This fact must be explained. The above ratio is a steady state condition and not equilibrium constant. This fact also must be explained. Concept introduction: Living plants have a definite C 14 / C 12 ratio. This ratio decreases when a plant is dead. This is due to the spontaneous decay of C 14 to N 14 7 along with the emission of beta particle. Given: C 14 / C 12 is constant for a living plant and the ratio is a steady state and not an equilibrium constant. Solution: a) All living plants have a constant C 14 / C 12 ratio. b) The ratio is not equilibrium constant rather it’s a steady state condition.

Question

1, How many signals do you expect in the H NMR spectrum for this molecule? Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute. to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule Check…

Question

Chapter 14, Problem 14.6PAE

Interpretation Introduction

Interpretation:

The ratio of

C14/C12 is a constant. This fact must be explained.

The above ratio is a steady state condition and not equilibrium constant. This fact also must be explained.

Concept introduction:

Living plants have a definite C14/C12 ratio.

This ratio decreases when a plant is dead.

This is due to the spontaneous decay of C14 to N147 along with the emission of beta particle.

Given:

C14/C12 is constant for a living plant and the ratio is a steady state and not an equilibrium constant.

Solution:

a)

All living plants have a constant C14/C12 ratio.

b)

The ratio is not equilibrium constant rather it’s a steady state condition.
