Devise a temperature scale, abbreviated g, for which the magnitude of the ideal gas constant is 1.00 j g–1 mol–1 .
melisa1 [442]

The value of ideal gas constant (R) in Joule is 8.314 Joule Kelvin^{-1}mol^{-1}. Now the given expression is 1.00 J. gg^{-1}.mole^{-1}. Where the g represent the temperature. Thus the abbreviated g must have the value 8.314 to satisfy the original value. Thus the temperature scale will be 1 kelvin = 8.314 g. Now 1 kelvin  = -272.15°C or in terms of abbreviation of g we can write -272.15 °C = 8.314g, or, 1°C  = (-) \frac{8.314}{272.15}=0.030g. Thus the temperature scale of the g scale is 1 kelvin (K) = 8.314g and 1°C = 0.030 g.

kobusy [5.1K]

Answer:

Explanation:

The algebraic sum of all the oxidation numbers of all atoms in a neutral compound is zero.

In order to know the formula of the negative Sulfur ion in pyrite, we must determine its oxidation state.

Let us make the make the oxidation number of sulfur = x

Therefore, FeS₂:

                      +2 +2x = 0

                      +2 = -2x

                       x = -1

The formula of the negative ion is S⁻
