Answer:

K₂EDTA

Explanation:

The additive in the lavender tube is potassium dihydrogen ethylenediaminetetraacetate (K₂EDTA).

EDTA is a powerful chelating agent, that is, it binds strongly to metal cations.

Its main function in hematology labs is to prevent the blood from clotting by binding the Ca²⁺ ions.

Answer:

= 49.674 g NaCl

Explanation:

From the equation;

1 mole of Sodium metal produces 2 moles sodium chloride

This means;

23 g of Na will produce 116.88 g of NaCl

Therefore;

11.5 g will generate;

 = (11.5 × 116.88)/23

 =  58.44 g of NaCl

But;

Percentage yield = (Actual yield/Theoretical yield)× 100%

         85 /100 = Actual yield /58.44 g

Thus;

Actual yield = 0.85 × 58.44

                  = 49.674 g NaCl

Which substance would have the highest melting point, based on electronegativity?
kenny6666 [7]

Water, H₂O, will have the highest melting point.

Explanation:

So here we have listed the hydrides of oxygen, sulphur, selenium and tellurium.

From this elements oxygen have the highest electronegativity and as a consequence the oxigen hydride (water, hydrogen dioxide) it is able to form hydrogen bonds between molecules. So you need more energy to overcome the interactions between molecules in water that for the other compounds.

Water, H₂O, will have the highest melting point between the listed hydrides.
