How do erosion and deposition work together to form sand dunes?
O Waves cause erosion along coastlines and deposit sand away from the shore,
Erosion occurs as surface water carries sediment and the sediment is deposited near oceans and lakes
O Glaciers cause erosion through the movement of large chunks of ice, which are deposited and form depressions
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction

The other person is 100% correct i took the test too

Explanation:

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.
