A student made the lewis dot diagram of a compound shown. What is the error in the Lewis dot diagram?
zloy xaker [14]

Answer:

B. Both electrons of Mg should be transferred to one O.

Explanation:

Metals react by loosing electrons while non metals react by gaining electrons.

Reactions occur as each element strives to attain an octet electron configuration in the outer energy level.

It is easier for magnesium to loose 2 electrons than to gain six because loosing the two requires less energy.

Oxygen on the other hand reacts by gaining the two electrons lost by magnesium since it is easier to gain the two than to loose the six. Gaining the two electrons for oxygen requires less energy than loosing the six.

In summary, magnesium looses two electrons that are transferred to oxygen.

A 50 L cylinder is filled with argon gas to a pressure of 10130.0 kPa at 300°C. How many moles of argon gas does the cylinder co
Vlad1618 [11]
To answer this question, we will use the general gas law which states that:
PV = nRT where:
P is the pressure of the gas = <span>10130.0 kPa
</span>V is the volume of the gas = 50 liters
n is the number of moles that we want to calculate
R is the gas constant = <span>8.314 L∙kPa/K∙mol
T is the temperature = 300+273 = 573 degree kelvin

Substitute with the givens in the equation to get the number of moles as follows:
</span><span>10130 * 50 = n * 8.314 * 573
506500 = 4763.922 n
n = </span>506500 / 4763.922
n = 106.3199 moles
