Choose all the objects which are true about the phases of the moon. (Hint: There are 4 correct answers.) Group of answer choices

phases are the shapes that the moon appears to have during the course of the month

A half circle moon is called a quarter moon.

A new moon occurs when the moon is between Earth and the Sun.

A full moon occurs when Earth is between the sun and moon

a new moon occurs when Earth is between the moon and sun.

A full moon occurs when the moon is between the sun and Earth.

a lunar cycle is approximately 28 days between new and full moon..

a quarter moon is a crescent moon

the answer is the first option

explanation:

just googled it m8. not that hard

lol

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
