Answer:
B.
Explanation:
Water expands on freezing and there is more water in the diet drinks than in the other drinks.
The three steps involve;
Step 1: Separation/expansion of the solute particles
Step 2: Separation/expansion of the solvent particles
Step 3; Combining the solute and solvent particles
The first two steps are usually endothermic. Step 3, nonetheless, can be either exothermic or endothermic and is significant in determining whether the dissolving process will be endothermic or exothermic.
Answer:
The correct answer is "A buffer resists pH change by neutralizing added acids and bases".
Explanation:
In chemistry, a buffer is defined as an aquoeous solution that resist pH changes. Buffers are comprised of a weak acid (HA) and its conjugate base (A−) in an equilibrium relation, which results in the buffer neutralizing added acids and bases. Buffers play a crucial role in living beings since they provide a relative stable environment for the cells in what is known as homeostasis.
