APA style has unique formats for in-text citations and reference pages. Its style and guidelines increase the ease of reading comprehension for viewers as well as ensure consistent presentation of content and written material.
In this calculation weâll use an ethane heat content of 66,500 BTU per gallon. The top boxes in Figure #1 show the conversion of the ethane price per gallon to dollars per MMbtu. So if the price of ethane is 22 cents, divide by 66,500 and multiply by 1,000,000 to yield an equivalent gas price of $3.31/MMbtu.
The complete structural formula for ethane is: Condensed structural formulas show the number of hydrogens around each carbon. The condensed structural formula for ethane is: CH3 â CH3. Another short-hand form of structural formula shows only the carbon atoms and the carbon-carbon bonds.It is understood that each carbon has four bonds. All bonds other than carbon-carbon are understood to be carbon-hydrogen.The short-hand for ethane is: C â C. Some resources may use another short-hand for longer alkanes. In this structure, there is a carbon atom at the end of each line segment (a total of 7).ll bonds other than carbon-carbon are understood to be carbon-hydrogen. The short-hand for ethane is: C â C.
