Answer:
HNO3(aq) + OH-(aq) → NO3-(aq) + H2O(l)
Explanation:
According to Bronsted-Lowry theory, an acid is a substance that donates a proton (H+) and produces a conjugate base while a base is a molecule or ion which accepts the proton.
An example of Bronsted-Lowry acid and base is Nitric acid, HNO3 and hydroxide ion, OH- respectively as shown in the given reaction.
Thus, the nitric acid acts as an acid by donating a proton to the hydroxide ion which accepts it, thus producing nitrate ion, NO3- as a conjugate base, while OH- produces H2O as a conjugate acid.
Answer:
0.441 L
Explanation:
At constant pressure, Using Charle's law :-
Given ,
V₁ = 0.500 L
V₂ = ?
T₁ = 25.0 °C
T₂ = -10.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
T₂ = (-10 + 273.15) K = 263.15 K
Using above equation as:
<u>New volume = 0.441 L</u>

Answer:
3.0002 moles
Explanation:
Data Given:
mass of NO₂ = 138.01 g
No. of moles NO₂ = ?
Solution
To find mass of sample mole formula will be used
mole formula
no. of mole = mass in grams / molar mass
Molar mass of NO₂ = 14 + 2(16)
Molar mass of NO₂ = 14 + 32 = 46 g/mol
Put values in above equation
no. of mole = 138.01 g / 46 g/mol
no. of mole = 3.0002 moles
no. of mole of NO₂ = 3.0002 moles
