Two gases and are found in the atmosphere in only trace amounts because they decompose quickly. When exposed to ultraviolet light the half-life of is , while that of is. Suppose an atmospheric scientist studying these decompositions fills a transparent flask with and and exposes the flask to UV light. Initially, the partial pressure of is greater than the partial pressure of Y. Will the partial pressure of X ever fall below the partial pressure of Y? If yes, calculate the time it take the partial pressure of X to fall below the partial pressure of Y.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
