It is 31.75g of copper is contained in .50 mole of copper.
The atomic mass of K is 39
from Avogadro's law
39g of K contains 6.02x10^23 atoms
therefore if
39=6.02x19^23
X=5.11×10^22
making X the subject of the formula
X= (5.11×10^22×39)÷6.02×10^23
X= 33g
MgO
MgI2
PbO2
PbI4
These are the possible compounds
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.
Answer:
