The density of corn syrup is 1.38 g/cm3.. which substance will float in corn syrup? a. graphite (2.16 g/cm3). b. glycerin (1.26 g/cm3). c. copper (8.9 g/cm3). d. silver (10.5 g/cm3)

B. glycerin (1.26 g/cm3).

Explanation: The substances with higher value of density than the density of corn syrup will sink and the substances with lower value of density than the density of corn syrup will float.

A.  graphite : has a density of which is higher than the density of corn syrup which is , Thus it will sink.

B. glycerin: has a density of which is lower than the density of corn syrup which is , Thus it will float.

C. copper :has a density of which is higher than the density of corn syrup which is , Thus it will sink.

D. silver: has a density of which is higher than the density of corn syrup which is , Thus it will sink.

"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."

girl imma just put my comment here because i need a couple point okurrttt
