1. Moles Fe = 209.7 g/ 55.847 g/mol= 3.75
The ratio between Fe and CO is 2 : 3
Moles CO = 3.75 x 3 /2 = 5.63
<span>Mass CO = 5.63 mol x 28.01 g/mol= 157.7 g
2. </span><span />2Na + 2H2O --> 2NaOH + H2<span>atomic weight of sodium is 23 48.7/23 = 2.12 moles of sodium
2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles
so multiply it by Avogadro's number1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen

Answer:
Carbohydrates, proteins, and nucleic acids are built from small molecular units. The small molecular units are called monomers
Explanation:
I'm not really sure if that was what you were looking for, but I remember learning this in biology. I'm sorry if this doesn't help.
Answer:
Yes, it is a cell present in the blood. It contains haemoglobin that helps in transporting oxygen from the lungs to the rest of the body. Our blood looks red due to this high no. of red blood cell present in it.

Answer:
provitamin, beta-carotene
Explanation:
<em>Beta-carotene</em> is an example of a <em>provitamin</em>. It is a less active form of <em>retinol (Vitamin A)</em> that is synthesized by plants. Animals i.e. humans, cannot synthesize or make use of this form of Vitamin A. It can only be made available for use in humans through normal metabolic processes. Humans can access this provitamin by consuming food that is rich in beta-carotene. When beta-carotene undergoes normal metabolic processes in the body, it is transformed into retinol, which is an active form of Vitamin A. Vitamin A is needed by humans for healthy skin, good vision and eye health, as well as maintaining strong immune system.
