2A1Cl3 + 3Na CO3→ Al2(CO3)3 + 6NaCl

Name the first reactant:

How many sodium atoms on the reactant side?

How many Oxygen atoms on the product side?

1. aluminum chloride

2. 3

3. 9

Explanation:

1. Know the names

2. reactants are on left side products are on right side

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

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
