When a chunk of ice left behind by a receding glacier melts, the water stays in the kettle, forming

Kettle lake

Explanation:

A kettle lake forms when a receeding glaciers leaves glacier behind in a shallow depression called a kettle.

Kettles and kettle lakes are products of glacier deposition. They are mostly attributed to the receeding phase of a glacier. The mouth of a retreating glacier are usually laden with a mix of melt water and sediments. As the glacier continues to retreat, it leaves behind stagnant ice that must have been buried with the sediment. When the ice melts, a kettle which is an hollow depression forms and the water in it makes it a kettle lake.

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.
