Salt water is considered a compound since water is H20 (conpound) and Salt with is NaCl.
Answer:
Reaction will move rightwards.
Explanation:
Hello there!
In this case, according to the proposed question, it turns out possible for us to figure out the effect of the addition of silver nitrate, by using the following representative equation for the formation of the silver chloride precipitate:
Now, due to the addition of silver nitrate, we will be actually adding silver ions to the solution, which means that, in terms of the Le Ch atelier's principle, the reaction will shift to the right towards the formation of more silver chloride precipitate.
Best regards!
Answer:
it will take that explosin 15.34 millisecond
Explanation:
as the speed is 767 and distance is 50 so time will be 767/50=15.34milliseconds
pH can be defined as negative logarithm of hydronium ion concentration .
pH can be mathematical represented as :
pH =-log [H+]
[H+]=2.3*10^-9
pH= -log[2.3*10^-9]
=8.64
Answer:
Change in entropy for the reaction is
ΔS° = -268.13 J/K.mol
Explanation:
To calculate the change in entropy for the balanced reaction, we require the natural entropy of all the reactants and products in the reaction.
3 NO₂(g) + H₂O(l) → 2 HNO₃(l) + NO(g)
From Literature.
S°(NO₂) = 240.06 J/K.mol
S°(H₂O) = 69.91 J/K.mol
S°(HNO₃) = 155.60 J/K.mol
S°(NO) = 210.76 J/K.mol
These are the entropies of the reactants and products under standard conditions of 298.15 K and 1 atm.
Note that
ΔS° = Σ nᵢS°(for products) - Σ nᵢS°(for reactants)
Σ nᵢS°(for products) = [2 × S°(HNO₃)] + [1 × S°(NO)]
= (2 × 155.60) + (1 × 210.76) = 521.96 J/K.mol
Σ nᵢS°(for reactants) = [3 × S°(NO₂)] + [1 × S°(H₂O)]
= (3 × 240.06) + (1 × 69.91) =790.09 J/K.mol
ΔS° = Σ nᵢS°(for products) - Σ nᵢS°(for reactants)
ΔS° = 521.96 - 790.09 = -268.13 J/K.mol
Hope this Helps!!
