Raise the boiling temperature
Answer:
F⁻(aq) + H⁺(aq) ⇄ HF(aq)
Explanation:
When aqueous solutions of potassium fluoride and hydrochloric acid are mixed, an aqueous solution of potassium chloride and hydrofluoric acid results. The corresponding molecular equation is:
KF(aq) + HCl(aq) ⇄ KCl(aq) + HF(aq)
The full ionic equation includes all the ions and the molecular species. HF is a weak acid so it exists mainly in the molecular form.
K⁺(aq) + F⁻(aq) + H⁺(aq) + Cl⁻(aq) ⇄ K⁺(aq) + Cl⁻(aq) + HF(aq)
The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the molecular species.
F⁻(aq) + H⁺(aq) ⇄ HF(aq)
Answer:
Q Line A
A: (a) 0 (b) 20
B: (b) 10 (c) 10
C: (c) 10 (d) 10
D: (d) 10 (e) 13
E: (e) 13 (f) 0
F: (f) 0 (g) 0
a: The velocity is whatever you need to see when you are specifically using a numberline so the answer for a is just 10
b: The velocity for this one is not as easy as the last one, its 7.
Explanation:
When you have a number line and your trying to find a numberline, you just have to subtract the smaller line to the largest number but if you are trying to find the velocity in beetween more than one thane you add the two biggest ones and subtract the smallest one and if you make a wrong move like add the biggest and smalles youll... still get the same answer so it doesnt matter really but its just easier to do the smallest one as the subtracting number just FYI. Happy spring break!
