Answer:
8.59 g
2.25 g
Explanation:
According to the given situation the calculation of grams of PbO and grams of NaCL is shown below:-
Moles of Pb(OH)CL is


= 0.0385 mol
Mass of PbO needed is

After solving the above equation we will get
= 8.59 g
Mass of NaCL needed is

After solving the above equation we will get
= 2.25 g
Therefore we have applied the above formula.
Answer:
La datación potasio-argón o 40K/40Ar es un método de datación radiométrica, surgido en la década de 1960, utilizado en geología y arqueología para datar rocas o cenizas volcánicas
100°C is 273 kelvins.
1°C is 2.73 kelvins.
I guess the closest would be north pole
This is a strong base / week acid reaction.
NaOH + CH3COOH
The equilibrium of this reaction is very displaced to the right leading to the formation of the products
Na CH3COO + H2O
Na CH3COOH is a ionic compound which in solutionn will be as Na (+) and CH3COOH(-)
=> CH3COOH + NaOH = CH3 COO(-) + Na(+) + H2O
So, the predominant species in the solution are the ions Na(+) and CH3COO(-).
In general, in an strong base / weak acid titration, the predominant species present at the stoichiometric point will be the cation of the strong base (Na+ in this case) and the conjugate base of the weak acid (the anion of the weak acid, which is CH3COO- in this case).
The answer is predominantly Na(+) and CH3COO(-); predominantly because it is an equlibrium which means that the rectants will also br present.
