Answer:
Highest energy will be equal to
Explanation:
Charged on doubly ionized helium atom
It is accelerated with maximum voltage of 3 MV
So voltage
Now energy is given by
So highest energy will be equal to

Answer:
The classification and illustrations are attached in the drawing.
Explanation:
It is possible to identify the pure substance observing the figure, since it is the only one that has 2 joined atoms (purple and blue) which forms a single compound.
On the other hand, the homogeneous mixture is identified by noting that its atoms are more united with respect to the heterogeneous mixture, highlighting that in homogenous mixtures the atoms, elements or substances are not visible to the naked eye and are in a single phase, instead in the heterogeneous mixture if they can be differentiated.
Answer:
The number of moles of O atom in mol of
= 1.6
Explanation:
1 molecule of contains 2 atoms of O
So, molecules of
contains
atoms of O.
We know that 1 mol of an atom/molecule/ion represents numbers of atoms/molecules/ions respectively.
So, molecules of
is equal to 1 mol of
.
atoms of O is equal to 2 moles of O atom.
Hence, 1 mol of contains 2 moles of O atom.
Therefore, mol of
contains
moles of O atom or 1.6 moles of O atom.
Answer:
s = 4.41 g/L.
Explanation:
¡Hola!
En este caso, considerando el escenario dado, se hace necesario para nosotros saber que la posible reacción de disociación la experimenta el cloruro de plomo (II) como se muestra a continuación:
Lo cual hace que la expresión de equilibrio se calcule como:
Y que en términos de la solubilidad molar, s, se resuelve como:
Ahora, convertimos este valor a g/L al multiplicarlo por la masa molar del cloruro de plomo (II):
