Given that 1 mole contains 6.02x10^23 molecules, 3.0x10^23 is just around half a mole. Then we check the number of moles for each choice:
A. This is approximately half a mole, since the molar mass of Br2 is 159.8 g/mol.
B. He has a molar mass around 4 g/mol, so this is 1 mole.
C. H2 has a molar mass of 2.02 g/mol, so this is 2 moles.
D. Li has a molar mass of around 6.97 g/mol, so this is around 2 moles.
Therefore the only choice that fits is A. 80 g of Br2.
Answer:
The type of reaction is a single-replacement reaction.
Explanation:
Mg switches places with H, leaving H by itself.
Answer:
The liver
Explanation:
The liver -
In human beings the location of liver is just in the upper right portion of the abdomen , exactly below the diaphragm .
Liver is present in specifically vertebrates , and is responsible for various metabolism , like producing hormones , decomposition of the red blood cells , regulating the storage of glycogen and the synthesis of proteins .
Liver is the main site for the process of gluconeogenesis , amino acid catabolism .
Liver is the very organ , that has full urea cycle .
Hence , from the given information of the question ,
The correct term is the liver .
Yo sup??
number of protons=number of electrons =8
but this is the condition when the molecule is neutral
since it has a +3 charge now therefore no of electron is
=8-3
=5
The correct answer is option B
Hope this helps
