the table shows the types of elements that form two componds. which of the following statements is true about how the bonding occurred to create the two compounds

Electrons are shared in compound X and transferred in compound Y.

1. ionic bonding  

Bonding that occurs due to electron transfer. Can occur in metal and non-metal atoms. To get stability, atoms release or bind electrons to get stable electron regulation from noble gases  

2. covalent bonding  

Bonding that occurs due to shared use of electron pairs  

The two bound atoms contribute their electrons to produce bonds  

Generally occurs in non-metallic elements  

So compound X = covalent bond (metal with metal) and compound Y= ionic bond(metal with non metal)

the answer is b. dilution

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
