Answer:
2
Explanation:
Answer:
d = 1.85 g/cm³
Explanation:
Given data:
Volume of sulfuric acid = 35.4 mL
Mass of sulfuric acid = 65.14 g
Density of sulfuric acid = ?
Solution:
1 ml = 1cm³
Formula:
d = m/v
d = 65.14 g / 35.2 cm³
d = 1.85 g/cm³
To determine the formula units in a unit cell, understand the type of the unit cell structure (simple cubic, body-centred cubic, or face-centred cubic) and apply the appropriate calculation for that type.
To determine the number of formula units in a unit cell, one must first understand what these terms mean. A unit cell is the smallest repeating unit of a crystal lattice. There exist several different types that affect formula unit arrangement and quantity, including simple cubic, body-centred cubic, and face-centred cubic.
A crystal lattice is a three-dimensional framework of atoms, ions, or molecules arranged in a repeating pattern. The formula unit is the lowest whole-number ratio of ions represented in an ionic compound. In a simple cubic unit cell, there's one formula unit, in a body-centred cubic cell, there are two, and in a face-centred cubic cell, there are four.
For instance, if you are dealing with a simple cubic arrangement the unit cell is composed of 8 atoms forming the vertices and each one is shared amongst 8 neighbouring cells, you have (8 x 1/8 = 1) formula unit per cell. Similarly, in a body-centred cubic, there is 1 atom in the centre fully inside, and 8 on the corners shared with neighbouring cells, hence (1 + 8 x 1/8 = 2) formula units per unit cell.

Answer:
John Dalton
Explanation:
John Dalton was the first scientist to give the atomic theory. According to Dalton:
Red blood cells are primarily formed in the bone marrow, specifically the red bone marrow. The process of producing these cells, known as hematopoiesis, begins at the embryonic stage and continues throughout a person's life, with adult hematopoiesis being largely restricted to certain bones in the body. New red blood cells are continuously produced due to their relatively short lifespan.
Red blood cells are formed in the bone marrow, specifically in the red bone marrow which is a loose collection of cells where hematopoiesis or the production of blood cells occurs. This crucial process of forming blood cells, including red blood cells, is introduced in the embryonic stage in the yolk sac. However, as the embryo develops, this function is taken over by the spleen, liver, and lymph nodes, with the bone marrow eventually assuming most hematopoietic functions. The red blood cells, along with white blood cells and platelets, are all produced in the red bone marrow.
In children, this process can occur in the cavity of long bones, but in adults, it is largely restricted to certain bones such as the cranial and pelvic bones, the vertebrae, the sternum, and parts of the femur and humerus. The lifespan of these cells is relatively brief, so new ones must be continuously produced to maintain healthy bodily functions.
