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.

A boy with pneumonia has lungs with a volume of 1.7 L that fill with 0.070 mol of air when he inhales. When he exhales, his lung
BlackZzzverrR [31]

Answer:

0.053moles

Explanation:

Hello,

To calculate the number of moles of gas remaining in his after he exhale, we'll have to use Avogadro's law which states that the volume of a given mass of gas is directly proportional to its number of moles provided that temperature and pressure are kept constant. Mathematically,

V = kN, k = V / N

V1 / N1 = V2 / N2= V3 / N3 = Vx / Nx

V1 = 1.7L

N1 = 0.070mol

V2 = 1.3L

N2 = ?

From the above equation,

V1 / N1 = V2 / N2

Make N2 the subject of formula

N2 = (N1 × V2) / V1

N2 = (0.07 × 1.3) / 1.7

N2 = 0.053mol

The number of moles of gas in his lungs when he exhale is 0.053 moles

astraxan [27]

Answer:

Calcium sulphate is the right answer for this question.

It is because calcium sulphate helps to obtain the hardness in water. hardness.

The presence of this resource is a main reason for permanent hardness.

Hard drinking water has moderate health benefits, but can pose serious problems for the industrial settings.
