4.48
pH=pKa+log([A-/HA])
25% deprotonated tells us that A- is .25 and that the rest (75% is protonated) thats .75.
4 = pKa + log

4 - log

= pKa
4.48=pKa
Answer:
The first one is a divergent plate boundary.
The second is a convergent plate boundary.
The third is a transform plate boundary.
Explanation:
False - the amount of inertia depends on the MASS of the object; the heavier it is, the slower it is, and the lighter it is, the faster it is.
I think it's E. heating of water
Because exothermic process discharges heat, causing the temperature of the prompt environment to rise
Please correct me if I'm wrong!! I'd be happy to fix it!! :)
I could not break unless you hit it with a sledge hammer
