Chemical formula that compound will be made up of the same elements in the same proportion or ratio. For example, any water molecule is always made up of two hydrogen atoms and one oxygen atom in a 2:1 ratio. If we look at the relative masses of oxygen and hydrogen in a water molecule, we see that 94% of the mass of a water molecule is accounted for by oxygen and the remaining 6% is the mass of hydrogen. This mass proportion will be the same for any water molecule. The alkene called but-2-ene has two isomers, which the chemical formula CHCH=CHCH
The Great Snow of 1717 The Great Snow of 1717 The Great Snow of 1717 was a series of snowstorms between February 27 and March 7, 1717 (Gregorian calendar) that blanketed the colony of Virginia and the New England colonies with five or more feet (1.5 or more meters) of snow, and much higher drifts. Snowfall may have occurred elsewhere, but settler population was sparse outside of New England at that time. The Great Snow is considered one of the benchmark storms in New England, often compared to the Great Blizzard of 1888 in severity. The winter, even prior to the Great Snow, had been
