answer: dorji will decide which drink is to be served to whom (customer) by doing the following litmus paper tests : (i) if the drink turns blue litmus paper to red, then the drink is acidic and hence will be served to first customer who wants acidic drink. (ii) if the drink turns red litmus paper to blue, then the drink is basic and hence will be served to another customer who wants basic drink. (iii) if the drink shows no change in colour with litmus paper, then it will be neutral drink. thus, it will be served to third customer. since, the soft drinks are edible. dorji can take the decision by tasting the drinks. acidic drinks will be sour to taste whereas basic drinks will be bitter to taste and neutral drinks will have no taste.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
