We are given with a <span>temperature of 273.15 Kelvin and a pressure of 101.325 kPa. Using PV=nRT rule of ideal gas, where P is pressure, V is volume, n is the number of moles, R is the gas constant and T is temperature, we can conclude that the conditions are under STP(standard temp and pressure) and one mole of this gas occupies 22.4 L of volume.</span>
Answer:
CnH2n+2 formula
Explanation:
Alkanes have the general formula CnH2n+2, so if an alkane had 7 carbon atoms, it would have the molecular formula C7H16.
The correct answer is A. Diamond is an example of elemental carbon. It is an allotrope of carbon where the atoms are arranged in a face-centered cubic crystal structure. It is less stable than the other allotrope of carbon which is graphite.
