All electromagnetic waves are amplitude, a characteristic frequency and wavelength, and the ability to travel through a vacuum at the same speed (the speed of light)
Answer:
The answers are in the explanation
Explanation:
For the equilibrium:
B(aq) + H₂O(l) ⇌ HB⁺(aq) + OH⁻(aq).
By LeChatelier's principle, the increase in the concentration of a reactant (for example) at equilibrium will change the system counteracting the increasing producing more product.
Thus,
A) Will the equilibrium constant for the reaction increase, decrease, or stay the same? Why?
.
The equilibrium constant is a thermodynamic constant that stay the same with the addition of a compound.
B) Will the concentration of HB⁺(aq) increase, decrease, or stay the same? Why?
By LeChatelier's principle, the addition of B will induce the formation of more HB⁺(aq) increasing the concentration.
C) Will the pH of the solution increase, decrease, or stay the same? Why?
As the addition of B induce the increasing of OH⁻, the pH of the solution will increase.
I hope it helps!
Answer:
66.4 mL
Explanation:
A 75.7% (v/v) value, means that f<u>or every 100 mL of rubbing alcohol, there are 75.7 mL of isopropanol.</u>
With the above information in mind, we can s<u>olve the problem by multiplying 87.7 mL by 75.7 %</u>:
87.7 mL * 75.7 / 100 = 66.4 mL
So there are 66.4 mL of isopropanol in 88.7 mL of rubbing alcohol.
Answer:
I think the answer is X if wrong i´m sorry
Explanation:
Answer:
B: 3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯
Explanation:
Potassium hydroxide (KOH) reacts with iron (III).
The normal balanced equation is;
Fe(NO3)3 + 3KOH = Fe(OH)3 + 3KNO3
Now the ionic equation will be;
3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯
