Its hydrogen atom is a high conductor of electricity
Data that can be measured, deals with numbers and length,height,area,volume etc.
Ln(P2/P1) = (L/R).(1/T1 - 1/T2)
<span>with P1 = 1 atm, P2 = 45.9 atm, R = 8.314 J/mol.K, T1 = 452.15 K, T2 = 695.15 K. This gave the latent heat L as 41.2 kJ/mol.K. </span>
<span>Using this value, and calculating the vapour pressure at 120°C = 393.15 K </span>
<span>ln(P2) = (41.2 x 10^3/8.314).(1/452.15 - 1/393.15) </span>
<span>which gives the vapour pressure P2 as 0.1931 atm = 146.7 torr. </span>
I believe that the answer for this question would be option A. 8 HOURS. Based on the given scenario above about a certain radioactive isotope placed near a Geiger counter, the half-life <span>of the isotope 32 hours later would be 8 hours. Hope this is the answer that you are looking for. </span>
the reaction is HF + NaOH which leads to NaF
