Answer:

- Se diferencian en que en los compuestos iónicos se ceden y aceptan electrones, mientras que en los covalentes de comparten.

- Se parecen en que los enlaces son formados por medio de los electrones de valencia y que en ambos compuestos la ley del octeto se debe cumplir.

Explanation:

¡Hola!

En este caso, debemos recordar que los compuestos iónicos se dan cuando se forman enlaces iónicos en los que el elemento más electronegativo tiene la capacidad de aceptar los electrones perdidos por el elemento menos electronegativo con el fin de cumplir la ley del octeto en la que 8 electrones deben ser exhibidos en la molécula. Por otro lado, los compuestos covalentes se forman cuando los átomos comparten sus electrones de valencia con el fin de alcanzar la ley del octeto.

De este modo encontramos que se diferencian en que en los compuestos iónicos se ceden y aceptan electrones, mientras que en los covalentes de comparten.

Por otro lado, ambos se parecen en que los enlaces son formados por medio de los electrones de valencia y que en ambos compuestos la ley del octeto se debe cumplir.

¡Saludos!

If two charged objects in a laboratory are brought to a distance of 0.22 meters away from each other. What is
zysi [14]

Answer:

q_2=2.47\times 10^{-4}\ C

Explanation:

The charge on one object, q_1=9.9\times 10^{-5}\ C

The distance between the charges, r = 0.22 m

The force between the charges, F = 4,550 N

Let q₂ is the charge on the other sphere. The electrostatic force between two charges is given by the formula as follows :

F=\dfrac{kq_1q_2}{r^2}\\\\q_2=\dfrac{Fr^2}{kq_1}\\\\q_2=\dfrac{4550\times (0.22) ^2}{9\times 10^9\times 9.9\times 10^{-5}}\\\\q_2=2.47\times 10^{-4}\ C

So, the charge on the other sphere is 2.47\times 10^{-4}\ C.

An ac generator has a maximum emf output of 150 V. What is the rms current in the circuit when the generator is connected to a 3
natima [27]

This is an insidious question.  Quite frankly, I would not have
expected to see it here on Brainly.  But I'm ready to play the
cards that you have dealt me.

None of the choices offered is a correct solution.

If the output of the AC generator is nice and sinusoidal, and
its maximum (peak) emf is 150 volts, then its RMS emf is

                             (1/2) (150) (√2)  =  106.07 volts.

The resistor's dissipation is   

                             Power = (current) x (voltage) .

If the resistor is dissipating its full rated 35W, then

                       35W  =  (current) x (106.07 V)

Divide each side by 106.07 V:   

           RMS Current =  (35W) / (106.07 V)  =  0.33 Ampere .
_________________________________________

Looking over the choices offered . . . 

The largest choice ... 3.1 A ... is the current in a resistor
that is dissipating 35W if the voltage is

                           (35W / 3.1A)  =  11.29 volts .

The smallest choice ... 1.2 A ... is the current in a resistor
that is dissipating 35W if the voltage is

                           (35W / 1.2A)  =  29.17 volts .

Whatever you meant the so-called "150 V" of the generator
to represent ... whether the RMS sinusoidal, peak sinusoidal,
peak square-wave, RMS square-wave, DC, average, etc. ...
none of the choices for current, in combination with any of these
generators, would dissipate 35W.
