Weathering is caused by precipitation reacting
with minerals in the rock.
Weathering is caused by freezing and thawing
of water.
Weathering creates new substances, such as
clay and salts.
Weathering is caused by the movement of
agents such as glaciers and wind. It is
accelerated by increases in velocity
Weathering is caused by processes such as

No please help me I need the right answers!!

c8h10 is your answerr

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants

the answer is barium and copper bromide

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
