<h3><u>Answer;</u></h3>
pH = 9.55
<h3><u>Explanation;</u></h3>
[NH3] = 2.0 mmol/20.0 mL = 0.100 M
[NH4+] = 1.00 mmol/20.0 mL = 0.0500 M
Ka = (1.0 × 10^-14)/(1.8 × 10^-5)
= 5.56 × 10^-10
pKa = log Ka = 9.25
pH = pKa + log ([base]/[acid])
= 9.25 + log (0.100/0.0500)
<u>= 9.55</u>
Implementing means to add something ie. "It's cool that you were able to implement the gummys into the root beer float"
Answer:
D.
Explanation:
You try to get 8 electron on the outermost "shell" so you have no left over or "valence" electrons.
answer i think your looking for unless your talking about something else
"Electric charge: the proton and electron are electrically charged, while the neutron is not. The proton and electron, however, are oppositely charged. Role in the atom: Protons and neutrons are closely bound together in the nucleus of an atom, while electrons are spread out around the nucleus."
