Which equation represents a neutralization reaction?
Harrizon [31]

Answer: HCI + KOH → KCI + H20

Explanation:

HCI(aq) + KOH(aq) → KCI(aq) + H20(l)

Acid + base → Salt + Water.

The above is a neutralization reaction in which an acid, aqeous HCl reacts completely with an appropriate amount of a base, aqueous KOH to produce salt, aqueous KCl and water, liquid H2O only.

This is a neutralization reaction since, the hydrogen ion, H+, from the HCl is neutralized by the hydroxide ion, OH-, from the KOH to form the water molecule, H2O and salt, KCl only.

What is the osmotic pressure of a 0.850 m solution of glucose in water at 35 °c?
Alik [6]

The osmotic pressure of the glucose solution is 21.49 atm.

From the question given above, the following data were obtained:

  • Molarity (M) = 0.85 M
  • Temperature (T) = 35 °C = 35 + 273 = 308 K
  • Van't Hoff's factor (i) = 1 (non-electrolyte)
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Osmotic pressure (π) =?

π = iMRT

π = 1 × 0.85 × 0.0821 × 308

π = 21.49 atm

Therefore, the osmotic pressure is 21.49 atm
