C) Heat from the water is transferred to the sidewalks

D) In order for the rain water to evaporate, it requires heat from its surroundings

3) The unit for energy is the joule (J). If the energy content of an object is 1,000 J, but then later it is found to be 900 J, what happened to 100 J of its energy?
A) Energy was destroyed.

B) The object transferred some of its energy to its surroundings.

C) Energy was created.

D) The object absorbed additional energy from its surroundings.

"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."

give me abc and i will get it for u.

it is b that is the answer.
