You didn”t provide any signs, however, commonly this question involves two electrons with opposite pointing arrows, one up and one down. If this is the case, this is supposed to show the opposite spin of two electrons. It would be the fourth y2kcenter.org if the lines pointed towards one another and electrons moved that way.
You are watching: What does the sign represent with respect to electrons?
How might the population of owls be affected if the population of grasshoppers were to suddenly decrease
The population of grasshoppers would increase becuase there arent as many owls to hunt?feed on them.
Hope this helps

Electrostatic force of attraction is the attraction between different molecules that comes from them being electrically charged.
For molecules to have an electrostatic force of attraction, they need to have opposing charges because like charges repel each other but opposite charges attract.
In the question above, the only option that has opposing charges is option D so this is the correct option.
Assume the reaction is the combustion of propane.
Word equation: propane plus oxygen produces carbon dioxide and water
Chemical eqn: C₃H₈(g) + O₂(g) ⟶ CO₂(g) + H₂O(g)
Balanced eqn: C₃H₈(g) + 5O₂(g) ⟶ 3CO₂(g) + 4H₂O(g)
(a) Table of enthalpies of formation of reactants and products
(b)Total enthalpies of reactants and products
ΔᵣH° is negative, so the reaction is exothermic.
A scientist studying earths magnetic field found that at hot springs Arkansas her compass pointed 5 degrees east of true north.
This is because the magnetic north pole and the geographic north pole are not in the same location. The magnet in the compass is attracted to the magnetic north pole not to the geographic north pole. There are different readings because she is also in two different places. Pls. see attachment that accompanies this question.
