A solution of calcium chlorate was poured into a sodium fluoride solution. Would you expect a precipitate to form if 255.0 mL of

the calcium chlorate solution (2.0x10-5 M) was mixed with 300.0 mL of a 2.5x10-3 M sodium fluoride solution? A. No, because Qsp < Ksp for calcium fluoride B. Yes, because Qsp < Ksp for calcium fluoride C. Yes, because Qsp = Ksp for sodium chlorate D. Yes, because Qsp = Ksp for calcium fluoride E. No, because Qsp = Ksp for sodium chlorate F. No, because Qsp < Ksp for sodium chlorate G. No, because Qsp > Ksp for calcium fluoride H. No, because Qsp > Ksp for sodium chlorate I. Yes, because Qsp < Ksp for sodium chlorate J. No, because Qsp = Ksp for calcium fluoride K. Yes, because Qsp > Ksp for sodium chlorate L. Yes, because Qsp > Ksp for calcium fluoride

Chlorine has two naturally stable isotopes: 35Cl (34.968853 amu) and 37Cl (36.965903 amu). The natural abundance of each isotope
allochka39001 [22]

Answer:

35Cl ⇒ 34.968853 amu  has an abundance of 30.05%

Explanation:

The molar mass of chlorine, (which is the average of all its naturally stable isotope masses), is 36.36575 amu.

There are 2 naturally stable isotopes, this means together they have an abundance of 100%

The isotopes are:

35Cl ⇒ 34.968853 amu  has an abundance of X %

37Cl ⇒ 36.965903 amu  has an abundance of Y %

X + Y = 100%   OR X = 100% - Y

36.36575 = 34.968853X + 36.965903Y  

36.36575 = 34.968853(1-Y) + 36.936.96590365903Y

36.36575 = 34.968853 -34.968853Y + 36.965903Y

1.396897 = 1.99705Y

Y = 0.699 = 69.95%

X = 100-69.9 = 30.05%

To control, we can plug in the following equation:

34.968853 * 0.3005 + 36.965903 * 0.6995 = 36.3658

This means

37Cl ⇒ 36.965903 amu  has an abundance of 69.95 %

35Cl ⇒ 34.968853 amu  has an abundance of 30.05%

Which set of numbers gives the correct possible values of l for n = 2
Paha777 [63]
HEY THERE!!

For a given principal quantum number or n, the corresponding angular quantum number or l is equivalent to a range between 0 and (n-1) .

This means that the angular quantum number for a principal quantum number of 2 is equivalent to:

l = 0 -> (n-1) = 0 -> (2-1) = 0 -> 1

So the answer is 0, 1

HOPE IT HELPED YOU.
