Wavelength of blue light = (3*10^8)/(6.98*10^14) = 0.4298*10^-6 or 430 nm
Answer:
The law of conservation of mass
Explanation:
The law of conservation of mass
Answer:
Hydrogen peroxide should be stored in
1) a cool environment
2) with amber bottles away from sunlight
3) with little drops of sodium phosphate
Explanation:
It has been confirmed that heat and light aids in the decomposition of hydrogen peroxide according to the equation; 2H2O2→2 H2O + O2.
This means that hydrogen peroxide must be stored in a cool place. This will reduce its rate of decomposition. Secondly, it should be stored in amber bottles away from light since light also aids in its decomposition.
Thirdly, drops of sodium phosphate may be added to prevent its catalytic decomposition during storage.
The answer is Nona-9, penta- is five, hexa- is six, and deca- is ten.
