Answer:
d) 2.12 V
Explanation:
E =E° - RT/nF log 1/H⁺ x HSO₄⁻
E = 2.08 - ( .059/2 X log 1/4.5x4.5 )
2.08 - (-0.038 ) = 2.118 =2.12 V

Well one possible problem is that a glass capillary tube may be too small to measure a temperature that high. The absolutely certain reason, however, is that at 110 degrees Celsius, the syrup would boil and the thermometer wouldn't be able to register the temperature of the gas.
Hope this helps!
Answer:
Atomic radius decreases moving from left to right across a period.
Explanation:
When we move left to right across a period, the size of atoms generally decreases. It is because within the period the outer electrons are in same valence shell and the number of electrons and proton increases moving from left to right across the the period. It increases the effective nuclear charge resulting in the increased attraction of electron to the nucleus that causes the decreased radius of the atoms.
