A. DNA is copied.
- The cell duplicates its DNA in order to have a complete set in eac cell when it divides.
Acids change the rate Corrosion and increase its temperature.
Formula for diarsenic pentoxide
As2O5
For the purpose we will here use the ideal gas law:
p×V=n×R×T
V= ?
n = 0.5 moleT= 273.15 K (at STP)
p= 101.325 kPa (at STP)
R is universal gas constant, and its value is 8.314 J/mol×K
Now when we have all necessary date we can calculate the number of moles:
V=nxRxT/p
V=0.5x8.314x273.15/101.325= 11.2 L = 11200 mL
Answer: D.
