Answer:
The answer is (H30+) =3,55e-8M and (OH-)=2,82e-7M
Explanation:
We use the formulas:
pH= - log(H30+) and Kwater=(H30+)x(OH-)
pH= - log(H30+) ----< (H30+)= antilog- pH=antilog- 7,45=3,55E-8M
Kwater=(H30+)x(OH-)
(OH-)=Kwater/(H30+)= 1,00e-14/3,55e-8 = 2,82e-7
Lead (IV) nitrate + sodium sulfate lead(IV) sulfate + sodium nitrate
Pb(NO3)4 (aq) + 2 Na2SO4 (aq) Pb(SO4)2 (s) + 4 NaNO3 (aq)
I think this is what you are looking for. If not I am sorry.
Answer:
<h2>1.806 × 10²³ atoms</h2>
Explanation:
The number of sodium atoms can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 0.3 × 6.02 × 10²³
We have the final answer as
<h3>1.806 × 10²³ atoms</h3>
Hope this helps you
I couldn't really find anything about the growth time but it does say that it could remain viable in soil for up to 40 years
