The logarithm from my understanding can never be negative. You can check this on a calculator. You may have a negative if it is shown as -(log x).
Carboxylic acid...........
Answer:
A
Explanation:
BF3 has a trigonal planar shape.
XeO3 has a trigonal pyramidal shape.
Using ideal gas formula (PV=nRT), you can conclude that volume directly related to the temperature. That means an increase in temperature will cause an increased volume too. Note that the temperature is using Kelvin, not Celsius. The calculation would be:
V1/T1= V2/T2
590ml / (-<span>55+ 273)K = V2/ (30+273)K
V2= (590ml/ 218K) * 303K
V2= 820ml</span>
