The field lines around one end of a bar magnet are shown below.
a vertical box labeled with a question mark. curved lines with arrowheads point into the top of the box from the top and sides.
based on the diagram, what can you conclude about the pole of the magnet?
it is a south pole because the field lines spread out from this end.
it is a north pole because the field lines spread out from this end.
it is a south pole because the field lines enter the magnet at this end.
it is a north pole because the field lines enter the magnet at this end.

The correct option here would be the third one because it is true.

Explanation:

The diagram shows a bar magnet that has lines that are parallel to each other and are pointing towards one side of the rectangle.

The side of rectangle is South Pole because the arrows that are shown in the diagram are nothing but field lines and these lines tend to start from North Pole and the arrow shows moving inside that point hence that point it would be South Pole showing field lines ending at it.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
