There are two ways to represent the chemical formula of a substance: in condensed form or in structural form. Ethane is an alkane which consist of two carbon atoms. Since the general formula for ethane is CₓH₂ₓ₊₂, the condensed formula is C₂H₆. The structural formula or the line-bond structure is shown in the attached picture.
Answer:
Equation S= (°C + 117.3)/1.956 °S(25°C) = 72.25°S
Explanation:
To know the difference between the scales, we must initially know the length of our new scale compared to the scale in Celcius degrees, for this we add the absolute value of our melting point and the boiling point | -117.3 ° C | + | 78.3 ° C | = 195.6 ° C
Because our new scale will be divided into 100 equal parts we can know the unit value of each degree ° C concerning degrees ° S. 195.6 / 100 = 1,956 ° C / ° S
For a linear relationship of the scales, the crossing point at ° S = 0.00 is equal to -117.3 ° C. whereby we can clear our equation to know the temperature in degrees Celcius from ° S
°C= -117.3 + °S * 1.956°C/°S
Clearing °S we obtain
°S = (°C + 117.3)/1.956°C/°S
(ii)
In this new scale the temperature of 25°C will be readed as
°S = (25°C+117.3)/1.956°C/°S = 72.25°S
