Question

question 16 1 pts as the concentration of hydrogen ions (h+) increases, the: solution becomes more basic. solution becomes more acidic. ph rises. both a and c are correct. question 17 1 pts the formation of sucrose involves the removal of a molecule of water. this is called: hydrolysis. oxidation. decomposition. dehydration synthesis. question 18 1 pts which of the following represents properties of water? high specific heat high heat of vaporization strong polarity all of the above

Explanation:

• Question 16: The pH scale is based on the concentration of hydrogen ions ($H^+$). As the $H^+$ concentration increases, the solution becomes more acidic and the pH decreases. A basic solution has a low $H^+$ concentration.
• Question 17: Dehydration synthesis is a chemical reaction where two molecules are joined together with the removal of a water molecule. Hydrolysis is the opposite (breaking a molecule using water), oxidation involves the loss of electrons, and decomposition is the breakdown of a compound into simpler substances.
• Question 18: Water has a high - specific heat (it can absorb a large amount of heat without a large temperature change), a high heat of vaporization (a lot of energy is needed to turn it into vapor), and strong polarity (due to the uneven distribution of electrons between hydrogen and oxygen).

Answer:

• Question 16: solution becomes more acidic.
• Question 17: dehydration synthesis.
• Question 18: All of the above
