[H₃O⁺]=4.4 x 10⁻⁴
pH=3.357
[OH⁻] = 2.28 x 10⁻¹¹
<h3>Further explanation</h3>
Given
HNO3 concentration = 0.00044 M
Required
[H3O+],[OH-] and the pH
Solution
HNO₃ = strong acid
HNO₃ ⇒ H₃O⁺ + NO₃⁻
[H₃O⁺]=[HNO₃]=4.4 x 10⁻⁴
For strong acid pH=-log[H₃O⁺]
pH=-log 4.4 x 10⁻⁴ = 4-log 4.4 =3.357
pOH+pH=pKw
pOH+3.357=14
pOH=14-3.357=10.643
pOH=-log[OH⁻]
Explanation:
for having a ionic bond we need great delta X that we see in electropositive atom (Na) and an electronegative atom(F)
Answer:
Decreasing the temperature will shift the equilibrium leftwards towards reactants.
Explanation:
Hello!
In this case, since the reaction between chromate anions and hydrogen ions yields dichromate anions, water and heat, we can infer this is an exothermic reaction by which heat is released (remember in endothermic reactions heat is absorbed as a reactant), it means that considering the LeChatelier’s which states that increasing the temperature of an exothermic reaction shifts the equilibrium leftwards since heat is a product, otherwise (decreasing the temperature) the equilibrium will be shifted rightwards.
Therefore, decreasing the temperature is the perturbation that will shift the equilibrium leftwards towards the reactants.
Best regards!
Answer:
Matter has mass and takes up space.
Explanation:
Matter is everything around you. Atoms and compounds are all made of very small parts of matter.
Mass is a measure of the amount of matter in an object.
