If the pH is 3.94 what is the concentration of H
solong [7]

Answer:

If pOH is 3.05, pH is 10.95 or

[H+]=1.122⋅10−11 mol/L

Explanation:

pH=−log(H+)Now, what is H+

if your pH is 10.95 (since pH+pOH=14, your pH=10.95).

(H+)=10 −10.95

(H+)=1.122⋅10 −11

This is your hydrogen ion concentration: [H+]=0.00000000001122  mol/L

A lake in rural maine drops in ph from 7 to 5 as a result of acid rain falling into it. how has the h+ ion concentration change

How long is a frozen turkey good for in the freezer?
Dmitrij [34]

Answer: Turkeys are good  for up to 2 years if frozen well in a good freezer

I recommend to at least cooking it within 1 year for the best quality if you cook it in 2 years it may lose some of its quality taste-wise.

if it's not frozen well check the texture and smell to see if its gone bad. it also depends on the type of turkey you are buying, depending on the turkey you purchase always check for an expiration date such as a butterball turkey,  so make sure you check their date.
