Carbon atom with iron and helium
klio [65]3 years ago
3 0

Answser: the representative unit of carbon dioxide is the molecule CO₂.


Justification:


1) carbon dioxide is made of one atom of carbon and two atoms of oxygen chemically bonded by covalent bonds.


2) A molecule is formed when two or more atoms are bonded by covalent bonds.


3) Some other examples of molecules are: water (H₂O), oxygen (O₂), the fats, the carbohydrates, glucose.


4) The term molecule is reserved for atoms bonded by covalent bonds, so ionic compounds like NaCl, are not named molecules. NaCl is told to represent a formula unit instead of a molecule.

What does iron do for the human body(two paragraphs)
Nitella [24]

Answer:

Hey mate....

Explanation:

This is ur answer.....

<em>Iron is an essential element for blood production. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.</em><em> </em><em>About 6 percent of body iron is a component of certain proteins, essential for respiration and energy metabolism, and as a component of enzymes involved in the synthesis of collagen and some neurotransmitters. Iron also is needed for proper immune function.</em><em> </em><em>About 25 percent of the iron in the body is stored as ferritin, found in cells and circulates in the blood. The average adult male has about 1,000 mg of stored iron (enough for about three years), whereas women on average have only about 300 mg (enough for about six months). When iron intake is chronically low, stores can become depleted, decreasing hemoglobin levels.</em><em> </em><em>When iron stores are exhausted, the condition is called iron depletion. Further decreases may be called iron-deficient erythropoiesis and still further decreases produce iron deficiency anemia.</em>
