Answer:
HI(aq) + NaOH(aq)-------------> NaI(aq) + H2O(l)
Explanation:
The molecular reaction between hydroiodic acid and aqueous sodium hydroxide is shown above. It is a reaction of one mole of hydroiodic acid with one mole of sodium hydroxide to yield salt and water only. It is a neutralization reaction. Hydrogen iodide dissolves in water to produce hydronium ions which agrees with Arrhenius description of acids. Hydroiodic acid is a strong acid with PKa of -9.3
Molar mass sucrose :
C12H22O11 = 342.29 g/mol
number of moles <span>of the solute :
</span>
n = mass solute / molar mass
n = 17.1 / 342.29
n = 0.05 moles
Volume in liters :
250 mL / 1000 = 0.25 L
therefore :
Molarity = moles of solute / volume
Molarity = 0.05 / 0.25 => 0.2 mol/L
1,000 grams = 1 kilogram
20 grams = 0.02 kilogram
Kinetic energy = (1/2) (mass) x (speed)²
(1/2) (0.02) x (15)² =
(0.01) x (225) = 2.25 joules
