Answer:
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. ... Protons and neutrons are bound together to form a nucleus by the nuclear force.
Explanation:
PH= pKa + log( conjugate base/ conjugate acid)
Answer:
( About ) 2.42 pH
Explanation:
First convert grams to mole of the hydrochloric acid,
HCl ( moles ) = 0.7g * ( 1 mole / 36.5g ),
0.7 / 36.5 = ( About ) 0.0192 moles
Now take the moles as a fraction over the given liters, to determine " M, " the apparent pH
M = 0.0192 mole / 5.0 L,
M = 0.00384M
_________________________________________________
Because HCl is a strong acid and will completely ionized, take a look at the steps below,
[ H+ ] = 0.00384M pH = -log[H+] = - log[0.00384],
- log[0.00384] = - ( - 2.41566... )
Solution = ( About ) 2.42 pH
Solid is the low energy state of condensed matter is characterized by structural rigidity
