Answer:

C. Lymphocytes

Explanation:

All of the following choices are kinds of white blood cells that have a significant role in the body's immune system.

A. Monocytes

Monocytes defend the body against infection by acting as macrophages. They are capable of eating up foreign bodies that may cause infection.

B. Neutrophils

Neutrophils are the most in number in the body's immune system, especially when there is inflammation. They are distributed to different areas where they can move through circulation along blood vessels. They specifically attack antigens.

C. Lymphocytes

Lymphocytes are further divided into two. These are the B cells and the T cells. The B cells are also of two kinds. One of them is the memory B cells, which can remember a foreign body and create antibodies against it to provide for a long-term resistance in case the body gets exposed to the same infectious agent again.

D. Basophils

As part of the immune system, basophils function for preventing blood clots as well as in mediating allergic reactions.

What is the pH of 500 mL of water after the addition of 1 mL of 2M NaOH?
Fudgin [204]

Answer:

pH = 11.60

Explanation:

When we add a base, we are increasing [OH⁻], so the pH will be totally basic.

pH of water = 7

Basic pH > 7

We are adding 2 M . 1 mL = 2 mmoles

2 mmoles of OH⁻ are contained in 501 mL of total volume.

[OH⁻] = 2 mmol / 501 mL =  3.99×10⁻³ M

- log 3.99×10⁻³ M = 2.39 → pOH

pH = 14 - pOH → 11.61

Water equilibrium

2H₂O  ⇄  H₃O⁺   +  OH⁻          Kw = 1×10⁻¹⁴

NaOH  →  Na⁺   +  OH⁻
