it again form new blood and this process is very fast process . our bone marrow form the RBC within one day ,that we loosed
They share four electrons, two from each oxygen atom
Answer:There is no change in identity of the substance and we can visually see a substance being drawn into wires. Hence ductility is not a chemical property, it is a physical property. Some examples of ductile materials, include metals such as copper, aluminium, silver, gold, etc.
Explanation:
Cu + 2H2SO4 ⟶ CuSO4 + SO2 + 2H20
In left hand side of the equation.
Cu = 1 atom
H = 4 atoms
S = 2 atoms
O = 8 atoms
In right hand side of the equation.
Cu = 1 atom
S = 2 atoms
0 = 8 atoms
H = 4 atoms
• All the atoms are balanced in the left and right side of the equation and it satisfies the law of conservation of mass.
• Equation is balanced and correct.
