The formation of these products usually involves THE FISCHER-TROPSCH PROCESS.
The Fischer-Tropsch process refers to a series of chemical reactions which convert hydrogen and carbon monoxide into liquid hydrocarbons in the presence of metal catalysts. The temperature utilized in the process is normally between 150 and 300 degree Celsius. The techniques was developed by Franz Fischer and Hans Tropsch in 1925. The technique is usually used to turn coal into liquid and to turn gases to liquid fuels.

Answer:
Explanation:1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
The white blood cells are the ones who leave the blood and enter tissues to fight off pathogens and invaders. They are not platelets because platelets help the healing of wounds and prevent it from bleeding by forming blood clots on the wounded area. They are not red blood cells because they carry oxygen all throughout the body organs. And they are not capillaries because capillaries are the ones that transports the oxygenated blood into the arteries.
antibodies is your answer
Answer: Option (d) is the correct answer.
Explanation:
Atomic number of argon is 18 and its electronic configuration is .
Also, it is known that number of electrons in K, L and M shells of argon are 2, 8, 8.
Thus, we can conclude that an atom of argon in the ground state tends not to bond with an atom of a different element because the argon atom has a total of eight valence electrons.
So, as per the octet rule, last sub-shell of argon is completely filled. Hence, it will not form any bond with any other atom.
