Mycobacterium avium, a human pathogen responsible for respiratory infections, sometimes found in hot tubs can be inactivated by many disinfectants including chlorine, chlorine dioxide and ozone. Concept introduction: Mycobacterium avium are resistant to chlorine, chlorine dioxide, and ozone. Chlorine susceptibility of cells was the same in washed cultures containing aggregates and in reduced aggregate fractions lacking aggregates. Cells of the more slowly growing strains were more resistant to chlorine than the cells of the more rapidly growing strains. Activation energy may also be defined as the minimum extra amount of energy absorbed by the reactant molecules so that their energy becomes equal to threshold value.

Interpretation Introduction

Interpretation:

Mycobacterium avium, a human pathogen responsible for respiratory infections, sometimes found in hot tubs can be inactivated by many disinfectants including chlorine, chlorine dioxide and ozone.

Concept introduction:

Mycobacterium avium are resistant to chlorine, chlorine dioxide, and ozone.

Chlorine susceptibility of cells was the same in washed cultures containing aggregates and in reduced aggregate fractions lacking aggregates. Cells of the more slowly growing strains were more resistant to chlorine than the cells of the more rapidly growing strains.

Activation energy may also be defined as the minimum extra amount of energy absorbed by the reactant molecules so that their energy becomes equal to threshold value.

To determine:

Heating an alcohol in the presence of sulfuric or phosphoric acid will cause a dehydration to occur: the removal of the elements of water from a molecule, forming an alkene. The reaction usually follows an E1 mechanism. The SN1 pathway is suppressed by using a strong acid whose conjugate base is a poor nucleophile. Further, heating the reaction mixture causes a greater increase in the rate of E1 compared to the rate of S№1. 2nd attempt 0 See Periodic Table See Hint Draw the organic intermediate from the first step (no byproducts) and draw curved arrow(s) to show how it reacts.
