Answer:
Lower the pH slightly
Explanation:
A buffer is defined as the mixture between weak acid and conjugate base. In the problem, acetic acid is the weak acid and sodium acetate the conjugate base.
When a strong acid as perchloric acid is added to a buffer, <em>the pH decreases slightly</em> because the acid reacts with conjugate base producing weak acid and not affecting directly the concentration of H⁺ ions.

M is molarity here not metre
Answer:
wave length=speed/frequency
=345/229
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
