If a liquid has a density of 1,200 g/l, what is its density in cg/ml? a. 1.2 cg/ml b. 120 cg/ml c. 12,000 cg/ml d. 120,000 cg/ml

B. 120 cg/ ml

Explanation:

If a liquid has a density of 1,200 g/L, what is its density in cg/mL?

To fin this, we will simply use the idea of proportion. But first we need to know the number of gram per liter  in 1 centigram per milliliter. Thus;

Let x = density of liquid in cg/ ml

1 cg/ml    = 10 g/l

  x          =  1,200 g/l

cross- multiply

10x =  1,200

Divide both-side of the equation by 10 to get the value of x

10x/10 = 1,200/10

(At the left-hand side of the equation, 10 on the numerator  will cancel-out 10  on the denomination and we will be left with just x, while on the right-hand side of the equation, 1200 will be divided by 1200)

x = 1,200/10

x =120 cg/ml

Therefore, the density of the liquid is 120 cg/ml

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
