Answer:

7.9

Explanation:

pH=-log([H+])

pH=-log(7.7×10⁻⁷M)

pH=6.113509275

Now, poH + pH = 14

Making poH the subject,

poH=14-pH

poH=14-6.113509275

poH=7.886490725

       ≈7.9

∴poH≈7.9

Calling all chemists...please help me!  Ive attached a screen shot of the problem
Olin [163]
This is an acid-base reaction where HF is the acid and H2O is the base (it's amphoteric and can be an acid or a base). The products would then H3O+ (the conjugate acid) and F- (the conjugate base). Now, we can simply construct a reaction using the found products and reactants. This acid-base reaction would be HF + H2O <--> H3O+ + F-.

Hope this helps!

A change in the core would have the greatest effect on what?
Misha Larkins [42]
<span>The magnetic field of the Earth serves a useful purpose in deflecting Solar radiation. Without the magnetic field there is much more charged-particle radiation striking the surface. The auroras would occur everywhere instead of at the magnetic poles. Compass needles wouldn't work, and then they would flip direction.. The magnetic field IS DECREASING and could go to zero and reverse sometime in the next few tens-of-thousands of years.</span>
