They are the same easily answer metals all the way
I can guess that Z is Phosphorus. So the oxide - P4O10 (but the most known its empirical formula P2O<span>5)</span>. Reaction with water:
P4O10 + 6H2O = 4H3PO4. Acidic compound is phosphoric acid.
1 ATP = 760 mm Hg
x ATP = 65.78 mm Hg
cross-multiply and you'll get:
0.08655 ATP
A chemical property refers to that which cannot be physically determined. From the choices given above, the chemical property of one of the student's materials is the reactivity of the copper strip. Thus, the answer to this item is letter B.
