D. Hippocrates
As quoted from Wikipedia, "he is often referred to as the "Father of Medicine"[1] in recognition of his lasting contributions to the field as the founder of the Hippocratic School of Medicine."
I hope this helps!
Cheers, July.
54.936 grams of NaCl will be produced from 33.0 g of Na and 34.0 g of Cl.
Explanation:
Data given:
mass of Na = 33 grams
mass of
= 24 grams
atomic mass of Na = 23 grams/moles
atomic mass of Cl = 70 grams/mole
mass of NaCl formed =?
atomic mass of NaCl = 58.44 gram/mole
balanced chemical reaction:
2Na +
⇒ 2NaCl
number of moles = 
putting the values in the equation:
number of moles of Na = 
= 0.69 moles
number of moles of chlorine gas = 
= 0.47 moles
limiting reagent is chlorine gas in the reaction
from the balanced chemical reaction:
1 mole of chlorine gas reacts to form 2 moles of NaCl
then 0.47 moles of chlorine gas will form x moles
= 
x = 0.94 moles of NaCl is formed.
mass = atomic mass x number of moles
mass = 58.44 x 0.94
= 54.936 grams of NaCl is produced.
Answer:
There are 10 types
Explanation:
Cytokines are the molecules produced by the immune cells involved in the immune response like the B cells, T cells, macrophages and other cells.
They are produced as a means of communication between the immune cells which could act as a signalling molecule. The chemical nature of these cytokines is that they are either the proteins or the glycoproteins.
There are many types of cytokine produced in response to antigens which could be interleukin, interferon which could play a different role.
These cytokines are present in more than 10 types of forms therefore the selected option is correct.
