When nonmetal atoms with differing electronegativities react, they form molecules with polar covalent bonds. Each element has an electronegativity value, which is a measure of the ability of an atom to attract and share electron pairs of another atom. Are you looking for the electronegativity value? I think this is correct
<span>A) This solution was not basic when it was heated in part 3. ( in part 3 i convertedCu(OH)2 to CuO).
Incorrectly low, because not all copper compounds will precipitate out
B) A slightly blue solution was decanted from Cu in part V. (in part 5 i reduced Cu(H20)6 ions with zink)
Incorrectly low, because some copper were thrown away
C) In part 5 the water in the beaker boiled away, exposing the evaporating dish to excess heat (same as above).
incorrectly high, because other compounds might be present as well </span>
Answer:
0.0521 M
Explanation:
HClO2 + NaOH ---> NaClO2 + H2O
M(HClO2)V(HClO2) = M(NaOH)V(NaOH)
M(HClO2)*41.6 mL = 0.146 M*14.85 mL
M(HClO2) = 0.146*14.85/41.6 M = 0.0521 M
B: Nitric Acid is the answer you are looking for.
