Answer:
Forumula
XOH + HY = XY + H2O
Explanation:
Salt formed from: Salt Solution
Strong acid + Strong base Neutral
Strong acid + Weak base Acidic
Weak acid + Strong base Basic
Neutral solution example
NaCl = Sodium chloride
HCl = H+ and Cl-
NaOH = Na+ and OH-
OH- = Strong Base
H+ = Strong Acid
Sodium chloride, formed from neutralization of HCl by NaOH.
NaOH + HCl = NaCl + H2O
NaCl in water is not acidic or basic, since it's ions cannot hydrolyze.
So formula would be XOH + YH = XY + H2O
The gas, 2 mol of H2, occupies the highest volume at STP since at STP the volume of this gas is approximately 44.8 mol as compared to other options this has the greatest amount.
I would say Na. Oxygen has 2 valence electrons and when reacting with other molecules, the ones with the fullest or emptiest shells will react the least. Both H2 and Na are in the Alkali Metals in the first row, but since H2 has 2 molecules, it would use more oxygen than Ana
