2 science questions I am a bit stuck on, help much appreciated thank you ^^ (cant attach files for some reason)
question - (b) Greenhouse gases cause global climate change.
Give two effects of global climate change.
1.

2.

question - (c) 4.1 kg of a plastic, used to make plastic bottles, has a carbon footprint of 6.0 kg of carbon dioxide.
Calculate the carbon footprint of one plastic bottle of mass 23.5 g

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

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
