A student made the table shown to list some contact and non-contact forces. Examples of Forces
Contact Forces
Non-Contact Forces
The force of air resistance on falling objects
The force applied by a student on a desk to move it
The force applied by a compressed
spring when it is released the force applied by an electromagnet on a wire
Which statement best explains why the table is incorrect? (8 points)
a
Spring force is a force acting at a distance.
Air resistance is a force acting at a distance.
The student and desk have to be in contact to apply the force,

The electromagnet and wire have to be in contact to apply the force.

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.

the answer is c
