<h3>The human skeletal system consists of all of the bones, cartilage, tendons, and ligaments in the body. Altogether, the skeleton makes up about 20 percent of a person’s body weight. An adult’s skeleton contains 206 bones. Children’s skeletons actually contain more bones because some of them, including those of the skull, fuse together as they grow up. There are also some differences in the male and female skeleton. The male skeleton is usually longer and has a high bone mass. The female skeleton, on the other hand, has a broader pelvis to accommodate for pregnancy and child birth. Regardless of age or sex, the skeletal system can be broken down into two parts, known as the axial skeleton and the appendicular skeleton. Axial skeleton anatomy</h3><h3>The adult axial skeleton consists of 80 bones. It’s made up of the bones that form the vertical axis of the body, such as the bones of the head, neck, chest, and spine. The adult skull comprises 22 bones. These bones can be further classified by location: Cranial bones. The eight cranial bones form the bulk of your skull. They help to protect your brain. Facial bones. There are 14 facial bones. They’re found on the front of the skull and make up the face.</h3><h3>Auditory ossicles </h3><h3>The auditory ossicles are six small bones found within the inner ear canal in the skull. There are three auditory ossicles on each side of the head, known as the: </h3><h3>malleus (hammer)</h3><h3>incus (anvil)</h3><h3>stapes (stirrup)</h3><h3>They work together to transmit sound waves from the surrounding environment to the structures of the inner ear. The hyoid is a U-shaped bone found at the base of the jaw. It serves as a point of attachment for muscles and ligaments in the neck. The vertebral column is made up 26 bones. The first 24 are all vertebrae, followed by the sacrum and coccyx (tailbone). The 24 vertebrae can be further divided into the Cervical vertebrae. These seven bones are found in the head and neck. Thoracic vertebrae. These 12 bones are found in the upper back. Lumbar vertebrae. These five bones are found in the lower back. The sacrum and coccyx are both made up of several fused vertebrae. They help support the weight of the body while sitting. They also serve as attachment points for various ligament. The thoracic cage is made up of the sternum (breastbone) and 12 pairs of ribs. These bones form a protective cage around the organs of the upper torso, including the heart and lungs. Some of the ribs attach directly to the sternum, while others are linked to the sternum via cartilage. Some have no attachment point and are referred to as “floating ribs.”</h3>

Aluminum sulfide : Al₂S₃

ratio cation : anion = 2 : 3

<h3>Further explanation</h3>

Given

Compound of Aluminium

Required

cations anions ratio

Solution

Salt can be formed from cations and anions which have their respective charges.

In the chemical compound formula these charges are crossed with each other

For aluminum it has a +3 charge

1. Aluminum carbide : Al₄C₃

ratio cation : anion = 4 : 3

2. Aluminum chloride : AlCl₃

ratio cation : anion = 1 : 3

3. Aluminum sulfide : Al₂S₃

ratio cation : anion = 2 : 3

4. Aluminum nitride : AlN

ratio cation : anion = 1 : 1
