Please do all of them. Thank you so much.

1. A reaction that produces a large molecule made of repeating units and many small molecules, such as water or hydrogen choloride, is a condensation polymerization reaction. 2. The following figures are examples of two DNA bases. DNA has a double-stranded structure that requires enzymes or high temperatures to separate the two strands because hydrogen bonds keep the strands together. adenine (A) thymine (I) 3. According to the collision theory, reactant entities that collide are the only collisions that can contribute to the chemical reaction. 4. The glass probe of a pH meter has a protective function, preventing ions from entering the solution within the probe. 5. Redox reaction spontaneity can be predicted based on experimental data
