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:
it is the objects mass, I learned this last semester
Answer:
When atoms lose or gain electrons, they become positively or negatively charged ions. In an ionic compound, the ions are arranged in a three-dimensional structure called a crystal. ... When an atoms gains or loses electrons, it gains a charge, thus becoming an ion.
Explanation:
Explanation:
It is known that for 
, ppm present in 1 
are as follows.
1 
= 0.494 ppm
So, 150 
= 
= 0.15
Therefore, calculate the equivalent concentration in ppm as follows.
= 0.074 ppm
Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
The turkey limits bc you can make 9 sandwiches with 9 turkey and 12 sandwiches with 25 bread
