Chlorine (Cl) is 76% chlorine-35 and 24% chlorine-37. Determine the average atomic mass of chlorine. Show/Explain work.
Flura [38]

Answer:

Average atomic mass of chlorine is 35.48 amu.

Explanation:

Given data:

Percent abundance of Cl-35 = 76%

Percent abundance of Cl-37 = 24%

Average atomic mass = ?

Solution:

Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (76×35)+(24×37) /100

Average atomic mass =  2660 + 888 / 100

Average atomic mass  = 3548/ 100

Average atomic mass = 35.48 amu

Average atomic mass of chlorine is 35.48 amu.

Arrange the following elements from greatest to least tendency to accept an electron. Rank from greatest to least tendency to ac
Schach [20]

Answer:

Cl-S-Si-Na-Mg

Explanation:

The elements want to have eight electrons in their outmost shell so that they are stable. Chlorine (Cl) is the one that has greatest tendency to accept an electron since it has 7 electrons, so it only needs one more to have a full shell and be stable, Sulfur (S) has 6 electrons, so it needs 2 more to have an outmost full shell, Silicon (Si) has 4 electrons in its outmost shell, so it needs 4 more to be stable, sodium (Na) has 1 electron in its outmost shell, so it needs 7 electrons, and Mg has 2 electrons in its outmost shell.

0 J

Work = Force * Displacement

Since displacement is 0 m (object isn't moving), work would also be 0.
