A Learning Task No. 6 : Fill in the blank with the correct answer. When some solid materials are heated, it absorbed heat. The heat absorbed/added to the material caused the material to change its form 1. to 2. The materials also changed its 4. and 5. when heated. from 3. When some materials are cooled, it removed/released heat. The heat removed/released from the materials caused the materials to change its form from 6. to 7. The material also changed its 9. and 10. when cooled. 8.

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.

there are two significant figures.

the answer is symmetrical : )
