8 0

Answer: The correct answer is option (A).

Explanation:

  • Dmitri Mendeleev published periodic table in 1869.
  • In his periodic table he arranged the elements in the increasing order of their atomic mass.
  • His periodic table consist total 63 elements.
  • He grouped the element on the basis of similarity of chemical and physical properties of the elements.

Hence, the correct answer is option (A)

Which temperature most likely corresponds to the asthenosphere?
iren2701 [21]

Answer:

A. 1613 °C

Explanation:

The asthenosphere is located just below the Earth’s crust.

It must be molten or semi-molten, so that convection currents can move the tectonic plates above it.

Rocks start to melt at about 1300 °C, so a temperature of 1613 °C sounds about right.

The normal boiling point of ethanol is 78.4 °C and 101.3 KPa. The heat of vaporization for ethanol is 42.32 kJ/mol. Determine th
Mandarinka [93]

Answer:

6.1×10^4Pa or 61KPa

Explanation:

The Clausius-Clapeyron equation is used to estimate the vapour pressure at different temperature, once the enthalpy of vaporization and the vapor pressure at another temperature is given in the question. The detailed solution is shown in the image attached. The temperatures were converted to kelvin and the energy value was converted from kilojoule to joule since the value of the gas constant was given in unit of joule per mole per kelvin. The fact that lnx=2.303logx was also applied in the solution.
