<span>The event that will happen to the following endothermic reaction that is in equilibrium if heat is added is that </span><span>The equilibrium would shift to the right. The correct answer from your choices is number 3.</span>
The reaction N2O4 (g) <--> 2NO2 (g) is endothermic, meaning that it consumes heat to move towards formation of the products. According to Le Chatelier's Principle, therefore, if heat is added, more product (NO2) will be produced, and equilibrium would shift towards the right side. This is choice 3.
The air pressure inside the can is lower compared to that of outside air pressure.
Explanation:
In general, the air pressure of an already opened can will be the same as the outside pressure.
Since the can is evacuated and remain as vacuum, so there will be no pressure difference in it.
If the can opens, air inside the can push the top and escapes to the outside.
This is due to high pressure experienced outside the cancompare to that of lower pressureinside the can and this may even cause can to collapse itself.
An is formed when an atom loses or gains one or more electrons. Because the number of electrons in an ion is different from the number of protons, an ion does have an overall electric charge.
