The newly-discovered element X (Xeruvium) is a transition metal that can have multiple oxidation states and has a molar mass of 37.70 g/mol. What is the molar
mass of the compound X(NO2)2?
129.72 g/mol
223.30 g/mol
O 167.42 g/mol
115.74 g/mol

c is the answer because when something is left after something evaporates that shows the chemical change.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

a polar bond is formed when electrons are shared unevenly between atoms

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
