Atomic number is 8 and atomic mass is taken as 16 amu
Answer:
Compared to early humans our brains seemed to have increased in size, and part of the cause may be because of things like Climage change, ecology and social competition
Explanation:
Answer:
At the cathode during the electrolysis of an aqueous solution of magnesium iodide, MgI2 , 2I−(aq) is produced
Explanation:
At cathode, reduction reaction takes place.
The dissociation of MgI2 in aqueous solution is Mg2+(aq) and 2I−(aq)
Here, the Iodine reduces to 2I−(aq) from state of 0 (MgI2) to state of -1 (2I−(aq))
Hence, at the cathode during the electrolysis of an aqueous solution of magnesium iodide, MgI2 , 2I−(aq) is produced
Answer is: Proteins-growth and repair of cellular structures.
Proteins are macromolecules made of amino acids (usually 20 amino acids) and they are main structure molecules of all living cells.
Lipids and sugars (glucose) are main source of energy in every living organism and they are used as the cell's energy reserves.
Molar mass=MM
MM(Hg)=200.59g/mol
MM(N)=14.01g/mol
MM(O)=16.00g/mol
MM(Hg(NO3)2)=MM(Hg)+2*MM(N)+6*MM(O)=200.59g+2*14.01g+6*16g=324.61g/mol
1.60mol Hg(NO3)2*(324.61g/mol)=519.376 g=519 g Hg(NO3)2
