Determine the molecular formula from the question above, knowing that the molar mass of the unknown is 329.31g/mol.

Solve (Limiting Reactant)

___HgBr + ___Cl2 -> ___HgCl2 + ___Br2

Identify the limiting reactant when 5.5 L of Cl2 is reacted with 89.5 g HgBr. How many grams of Br2 will be formed?

"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."

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
