Barium (Ba) has the lowest electronegativity of the choices you have given. 

The electronegativity of Calcium (Ca) is 1
The electronegativity of Strontium (Sr) is 0.95
The electronegativity of Magnseium (Mg) is 1.31 (has the highest)
The electronegativity of Barium (Ba) is 0.89

Of the list above, you can see that Barium has the lower level of electronegativity (0.89). Therefore, the correct answer is D. 

Let me know if you need further info.

How do you represent a shared pair of electrons when drawing the Lewis structure of a covalent bond
nataly862011 [7]

Answer: Each pair of shared electrons is a covalent bond which can be represented by a dash.

Explanation:

In a Lewis dot structure, the central atom can share electrons through bonds with the surrounding atoms, and this can look like a dash between the atoms.

Toluene, c6h5ch3, is a liquid compound similar to benzene, c6h6. it is the starting material for other substances, including tri
babymother [125]
Toulene = 35.6 g 
Benzene = 125 g = 0.125 kg
 Molecular weight of Toluene C6H5CH3 = 92.1g/mol
 Moles of toulene = 35.6 g / 92.1 g/mol = 0.3865 mol

 Now the molarity of the toulene in the given solution = 0.3865 / 0.125 = 3.092 m 
 Molarity of C6H5CH3 = 3.092 m
