Question

question 23 2 pts a biologist isolates a large, unidentified molecule from some cells in his lab. he determines that the macromolecule breaks into smaller pieces with the concomitant loss of water. what reaction has he observed? hydrolysis condensation dehydration question 24 2 pts what type of chemical bond stabilizes crystals of table salt? covalent bonds hydrogen bonds ionic bonds

Explanation:

For Question 23, hydrolysis is a reaction where a macromolecule breaks into smaller pieces with the addition of water (equivalent to loss of water from the macromolecule's perspective in the context of the reaction products). Condensation is the opposite, forming larger molecules with water release, and dehydration is the removal of water from a single - molecule context, not breaking a macromolecule into smaller ones.
For Question 24, table salt (NaCl) is composed of sodium ions (Na⁺) and chloride ions (Cl⁻). Ionic bonds are formed between oppositely - charged ions, which stabilize the crystal structure of table salt. Covalent bonds involve sharing of electrons between atoms, and hydrogen bonds are weaker intermolecular forces between polar molecules.

Answer:

Question 23: Hydrolysis
Question 24: Ionic bonds
