Dorji has a few bottles of soft drink in his restaurant. but unfortunately, these are not labeled. he has to serve the drinks on the demand of customers. one customer wants acidic drink, another wants basic and third one wants neutral drink. how will dorji decide which drink is to be served to whom?

Use a litmus paper

Explanation:

If u used a blue litmus in an acidic drink,then it will make the litmus paper red.

If u use a red litmus in a basic solution, it will turn blue.

If u use any of this in a neutral solution, there ain't gonna be no color change.

I hope this satisfies you.

Feel free to ask further questions.

I hope u Wil follow me and make this the brainliest answer.

um i think it might be a car?

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
